Kasdin and Members of the City Commission DATE: April 15, 1998 FROM: Sergio Rodriguez City Manager SUBJECT: UPDATE 0 FPL'S FREQUENT POWER OUTAGES AND PLANNING TO MEET FUTURE ELECTRICAL DEMAND AND REPORT ON FPL'S PLANS TO UPGRADE THE ELECTRICAL TRANSMISSION SYSTEM Attached is a report from FPL on service unavailability within the City of Miami Beach. This index serves as a measurable indicator to monitor the results of the improvements which are contained in the "Miami Beach Study", prepared by FPL in 1997. As part of the effort to upgrade facilities and meet future electrical demand, FPL is planning to install a transmission line that will run between 41 st Street and the area of 20th Street and West Avenue. According to the study, this transmission line is needed by June, 2000 in order to provide required capacity to the sub-stations. (see attachment) FPL is planning an overhead installation and the City Administration has requested that this line be placed underground. A series of meetings has been held with FPL to discuss alternate routes, methods of installation and estimated costs for the new transmission line. FPL has advised the City that under present rules and regulations governing the utility company, FPL is required to implement the lowest cost alternative for installation oflines. In the case of the new transmission line, an overhead installation is the least costly. The City would therefore have to pay for the cost differential for the underground installation of this line. On February 18, 1997 this matter was referred by the City Commission to the Finance and Citywide Projects Committee. At its March 12, 1998 meeting, the committee recommended that the City hire a consultant to look at the various alternatives; develop financing options; and referred the item to the City Commission. At the March 18, 1998 commission meeting, the City Commission directed the Administration to hire a consultant to study and make recommendations on this matter; requested the City Attorney's Office to research applicable Public Service Commission (PSC) rules which might govern the installation of transmission lines; develop financing options; and report back to the City Commission in 30 days. Since that time, the City has hired the consulting firm of Resource Management International, Inc. (RMI), to analyze and evaluate options available to the City to address the proposed installation of the transmission line. RMI's report, dated April 9, 1998, is attached. As requested by the City Commission, a response from the City Attorney's Office regarding PSC rules is attached. A summary of financing options has been developed and is also attached. AGENDA ITEM ~ DATE~ In reaching a determination the following should be noted: o the existing transmission system serving Miami Beach is an underground system o the improvements identified by FPL are in response to the need to upgrade the existing transmission system to provide for single contingency design. FPL is proposing to accomplish this upgrade by building an overhead transmission line which runs from the 40th Street substation to the Venetian substation o FPL, while desiring to contain its costs, is able to use its discretion in responding to a local community's needs. In the case of Miami Beach, an additional overhead transmission line running along one of the City's main arterial roadways is highly undesirable and unacceptable to the residents of the City o recently, FPL has completed several projects to upgrade its system and has selected to place these installations underground, including a major duct bank along Collins A venue to serve the Loews Hotel o FPL should consider a different approach for implementing the improvements to the transmission system, other than what has previously been suggested by FPL to the City, an approach which would respond to FPL's needs as well as those of the City of Miami Beach. Based on the foregoing, it is the Administration's recommendation that a formal request be made of FPL that, any upgrades to the electrical transmission system serving Miami Beach be implemented, at their sole cost, in a manner consistent with the existing underground configuration of the present transmission system; namely, underground/underwater installations. This, we believe,FPL has the ability to implement, by exhibiting sensitivity to the area, using its discretion under current applicable PSC rules and State Statutes, and electing to place such installations underground.

Service Unavailability is the average number of minutes that service is not available to our customers. The attached two graphs represent Service Unavailability for the City of Miami Beach. Chart 1 illustrates the average number of minutes a Miami Beach resident or business was without electric service each month. This chart compares each month in 1998 to the same month in 1997 and 1996. Each bar represents the average number of ~inutes for that month that customers were without electric service. In February 1998, Miami Beach customers were without electric service an average of 6 minutes compared to 12 minutes in February 1997. Chart 2 illustrates the average number of minutes a Miami Beach resident or business was without electric service within the last twelve months. In February 1998 Miami Beach customers were without electric service just under three hours on average (177.1 minutes).

This study showed that the transmission system serving the load in the northernmost stations 40th Street, Indian Creek, Deauville and Normandy Beach was adequate for the next ten years. However, due to the rapid load growth being projected for the southernmost area of Miami Beach a need to expand the transmission capacity in this area was identified. Loads in the southernmost Miami Beach area are served by two 69kV cable and one 138kV cable; The Miami - Miami Beach 69kV cable (rated at 113 MV A), the 40th Street-Miami Beach 69kV cable (rated at 114 MV A) and the Miami-Miami Beach 138kV cable (rated at 243 MV A). There are six substations in the. area being served by these cables, i.e., Simpson, Key Biscayne, Virginia Key, Miami Beach, Roney and Venetian. From 1991 to 1995, load growth in this area has been significant averaging 5.5% per year. Also, projected load growth forecast continues to indicate that these high levels of load growth will be sustained. The need for this evaluation during the summer of 1996 was initiated due to concerns over the ability of the transmission network in the area to reliably serve the amount of load growth being projected. From FPL's "Niami Beach Study" Dated: February 1997 The latest re-evaluation of the area led to the following: Utilizing single contingency assessment methods (loss of a single element in the system) the need for additional transmission capability to meet the growing needs of the Miami Beach area was identified. FPL's evaluation found the attached system improvement (see Map) to be the most reliable and cost-effective way of meeting the short and long range capacity need of the area. This system improvement entails the following: By June 1, 1998: - Shift 16 MV A of load from Simpson substation to Latin Quarter substation by building additional distribution feeders. By June 1, 20(\0: - Build a 69kV line from 40th Street to Venetian substation of approximately 1.8 miles in length. - Installing a 2.5 MV A series reactor at Miami substation. Budget - There is currently $7,140,000 in the budget for the 40th Street - Venetian Project and Transmission cable.

ORLANDO, FLORIDA Unpublished Work @ April 1998 04/09/98 THU 16:18 FAX 407 895 6486 R M lOR LAN D 0 I4J 002 TRANSMISSION LINE REVIEW OF ALTERNATIVES AND COST ANALYSES BACKGROUND Florida Power & Light Company (FPL) has provided electric service to the Miami Beach area for many years. The existing submarine and underground transmission lines serving the area were installed over 30 years ago. The lines provide multiple feeds to the islands comprising the City of Miami Beach. There are fOUI underground/submarine lines across the Intracoastal Waterway connecting the mainland electric grid to the Miami Beach backbone transmission system. The backbone is comprised of 69-kV underground/submarine cables linking the northernmost Deauville substation to the southernmost Miami Beach Substation. There is also a 1.3 mile section of 69-kV overhead line between the Deauville substation and the Normandy Beach substation. This overhead line provides another source of power to the Miami Beach 69-kV transmission backbone. The existing transmission lines serve six substations within the Miami Beach City limits. The Normandy Beach substation, although not located within <:::ity limits, also serves loads within the City. With minor vanations, the existing transmission, substation and distribution systems have provided reliable service to the citizens of Miami Beach for a long time. On January 20, 1982, the City Commission passed and adopted Ordinance No. 82- 2294 granting Florida Power &. Light Company an Electric Franchise that became effective January 22, 1982. The franchise term is 30 years from the date of acceptance and will expire in the year 2012. FPL and the City are currently operating under this franchise which grants FPL the right to generate and sell electric power and to construct, maintain and operate electric light and power facilities within and beyond the City limits. In 1996, as a result of complaints from the citizens of Miami Beach, the City asked FPL to investigate the decline in the quality of electric service it provides customers within the City. FPL responded by conducting transmission, substation, and distribution systems studies. The results of the studies were summarized and presented to the City in a Report on Frequent Power Outages and Planning- to Meet Future Electrical Demand. The report also provides a plan for improving service reliability. The proposed pIan identifies specific transmission, substation and distribution system CITY OF MIAMI BEACH APRIL 9, 1998 PAGE 2 OF 15 04/09/98 THU 16:19 FAX 407 895 6486 R M lOR LAN D 0 I4J 003 upgrades and modifications intended to improve service reliability and to meet future electrical demands. FPL presented the report to the City Commission on February 14, 1997. One of the projects proposed by FPL is to build a new 69-kV, overhead transmission line from the 4()th Street substation to the Venetian substation. The line would be 1.8 miles in length, concrete pole construction, and routed along Alton Road on the west side or the Bayshore Municipal Golf Course. According to FPL's report, this new line is required "due to the rapid load growth projected for the southernmost area of Miami Beach." . Since FPL submitted their report to the City, several meetings were held between FPL representatives and. City staff. In addition, FPL representatives have appeared before the City Commission to explain various aspects concerning the justification, and proposed routing, construction, and scheduled in-service date for the new line. In March 1998, to assist in the evaluation of outstanding technical issues, the City contracted Resource Management International, Inc. (RMI) to provide technical assistance in evaluating various unresolved issues regarding the new line. On March 24, 1998, RMI's representative, Frank Alonso, met with City staff to define !:he City's main concerns regarding lhe proposed new line. Owi.ng the meeting, the following areas of concern were identified: · Are there any provisions in the City Charter or franchise ordinance that reguJates the placement of new or replacement transmission lines? . he there state or federal guidelines regarding underground or overhead placement of new or replacement transmission lines? · Is the new line required? Is it justified? · Are overhead and underground versions of the proposed line the only alternatives? Are there others? · he FPL's cost estimates reasonable? · Is the City required to pay the differential between overhead and underground construction? . Is FPL's in-service date reasonable? On March 24, Oty staff and RMI's representative also met with FPL's representatives to request additional information regarding justification of the line, assumptions FPL made in preparing their cost estimates, and what alternatives they considered. A written list of questions was provided to FPl representatives after the meeting. They agreed to respond in writing by Friday, March 27, submitting their responses directly to RMI with copies to the City. For the most part, the answers were received as promised. Copies of the questions and responses are in Appendix A. eln OF MIAMI BEACH APRIL 9,1998 PAGE 3 OF 15 04/09/98 THU 16:20 FAX 407 895 6486 R M lOR LAN D 0 141 00 <I ANALYSIS Following is our analysis and evaluation of the areas of concern to the City that were identified during the March 24 meeting. Are there any provisions in the City franchise ordinance that regulates the placement of new or replacement transmission lines? We reviewed the existing franchise ordinance and it does not limit or specify the placement of new or replacement transmission facilities within the City. Section 3 of the ordinance does include the following: "".The location or relocation of all facilities shall be made under the supervision and with the approval of such representatives as the governing body of the Grantor (City) may designate fOT the purpose, but not so as to unreasonably interfere with the proper operation of the Grantee's (FPL's) fllcilities Ilnd service." Thus, the ordinance requires that FPL obtain the City's approval prior to building any fadlities within City limits. Although we are not qualified to render a legal opinion on this matter, we believe this requirement cannot be interpreted as giving the City the right to require FPL to place new or replacement transmission and distribution facilities underground. In fact, the Cirys rights to regulate the placement of transmission and distribution facilities within City limits were significantly constrained by the May 2, 1991, decisiun by the Supreme Court of Florida in the Florida Power Corporation v. Seminole County Case. In that decision, the Florida Supreme Court upheld the jurisdiction of the Florida Public Service Commission (FPSC) to regulate rates and services of public utilities versus the authority of cities and counties to require electric utilities to place their lines underground. Are there state or federal guidelines regarding underground or overhead placement of new or replacement transmission lines? Recent and past rulings by the Florida Supreme Court and the FPSC do not make a distinction between transmission and distribution lines regarding the issue of line placement. Currently, there are no federal regulations regarding the placement of new transmission or distribution facilities overhead or underground. CITY OF MIAMI BEACH ApR.IL 9, 1998 PAGE" OF 15 04/09/98 THU 16:20 FAX 407 895 6486 R M lOR LAN D 0 141005 The State uf Flurida's Transmission Line Siting Act only regulates new transmission lines rated 230-kV and above and does not include any provisions for requiring new or replacement facilities to be installed underground. It also does not require that replacement facilities be "like-for-like", Since the proposed line is rated 69-kV, it is not covered by this siting act. We contacted the FPSC to obtain information regarding any rules or reguIaUons they have concerning the placement of new or replacement transmission or distribution lines overhead or underground. According to the FPSC representative we spoke with, the FPSC has no written rules or regulations that directly impact the construction, maintenance, operation or placement of transmission or distribution facilities. The FPSC regulates the rates charged by public utilities and the service they provide their customers. These regulatory functions of the FPSC indirectly impact FPL's da.isiun to place all new or replacement transmission lines overhead. As an investor owned utility (IOU) in the State of Florida, FPL operates as a monopoly. Within its service area it has no competition as an electric service provider. To protect its customers, FPL's financial operations are closely regulated by the FPSC. The commission approves all rate changes and decides which expenses FPL can include in determining revenue requirements. Following FPSC past rulings requiring utilities to provide reliable, low cost electrical service and in keeping with past FPSC rulings regarding admissibility of expenses for inclusion in the rate base, FPL established their standards for transmission line construction so that all new 1i.nes are located overhead. On the other side of the issue, the FPSC is vested with the authl?rity to require conversion of overhead lines to underground where "feasible" if the conunission finds this to be "cost-effective". It is also within FPL's discretion to make exceptions to their standard transmission line design and construction practices. They have done so on several occasions in the past. CITY OP MIAMI BEACH APRIL 9,1998 PAGE 5 OF 15 04/09/98 THU 16:21 FAX 407 895 6486 R M lOR LAN D 0 141 006 Recently, FPL chose to place underground several new and replacement lines in Miami Beach. Following is a listing of some of those projects: From To 1. 8th Street Alton Rd. Collins Ave, 2. 6th Street Alton Rd. Michigan Ave. 3. Michigan Avenue 6th Street 8th Street 4. Sub-aqueous feeder along Miami Beach Substation Aiton Rd. East bridge on 5th Street 5. Pine Tree Drive 42nd Street 43ni Street 6. Collins Avenue Esplanade Way 19th Street 7. 15th Street Collins Avenue Ocean Drive 8. 4th Street Alton Lenox 9. Collins 4th Street Biscayne 10. South Lincoln Lane Lenox Pennsylvania FPL representatives have not indicate under what conditions they would make an exception to their standard overhead construction practice and locate a line underground without the customer paying for the differential cost between underground and overhead line construction. According to information they provided, "FPL is obligated to provide its customers 'With reliable, low cost electrical service. Current electric utility industry technology and FPL standards permit FPL to build overhead transmission lines which meet this obligation to serve. This MS al'ways been FPL' s standard far transmission lines. If a request is made to deviate from this standard (underground) the requesting party pays for the rosts of deviating from this stnndard. n Obviously, since all the existing transmission lines in the City of Miami Beach are underground, there have been exceptions to their standard practice in the past. .Why were the existing lines placed underground or underwater? FPL representatives were asked this question. TIley said th~y had researched their files, but were not able to locate any documentation regarding FPL' 5 past decision (30 years ago) to place the lines in Miami Beach underground. CITY OJ:' MIAMI BEACH APRIL 9,1998 PAGE 6 OF 15 04/09/98 THU 16:21 R~ 407 895 6486 R M lOR LAN D 0 @007 The existing facilities in Miami Beach show that exceptions to FPL and industry standard practice were made in the past. Those past decisions to deviate from standard practice must have been based on very strong reasons, because the comparative cost for placing transmission lines underground 30 years ago was definitely higher than it is today. FPL staff may not have documentation regarding the original decision to place existing lines underground, but just the fact that they are i.. a very compelling reason to place the new line underground at FPL's expense. Is the new line required? Is it justified? The FPL report, dated February 1997, justifies the addition of the new line based on the need for additional transmission capacity required to serve the increasing loads in the southernmost area of Miami Beach. In our discussions with FPL personnel, we now understand that the line is mostly required to satisfy reliability concerns. Line Capacity Retfuirements FPL's report states that the new line is required to "expand the transmission capacity" to the southernmost area of Miami Beach. In their most recent appearance before the City Commission, FPL representatives said the line is required to improve system reliability. 1his discrepancy was explained by FPL representatives during our March 24 meeting. Their revised load growth forecast now indicates that if the additional capacity provided by the new line is not in-service by June 1999, there could be extensive and prolonged outages Iesultin~ in reduced service reliability. According to FPL's report, trom 1991 to 1995, loads in the southern part of the City increased an average of 5.5% per year and will continue to grow at the same high levels through the time scope of their load growth forecast. If system capacity is not increased, the continued high load growth will eventually result in system overload conditions during peak consumption periods. Currently, there are three substations serving the south Miami Beach area. They are Roney, Venetian, and Miami Beach substation. There are another three substations fed by the same sources. Those six substations are fed by two 69-kV cables rated 113-MV A and one 138-kV cable rated 243-MV A. The total capacity of the three cables is 470-:MV A. According to information provided by FPL, the metered load in 1997 for the southern area of Miami Beach was 234-MVA (assuming a power factor of 85%). FPL anticipates the total load in south Miami Beach to reach 258-MV A by the summer of 1999. With all three cables in service, their combined 470-MVA provides sufficient transmission capacity to serve even the projected 1999 load (234-MV A). Based on the previous comparison between projected load and existing line capacities, there is no need for additional transmission capacity. CITY OF MIAMI BEACH APRIl 9, 1998 PAGE 7 OF 15 04/09/98 THU 16:22 R\X 407 895 6486 R M lOR LAN D 0 I4J 008 Reliability Concerns Because the Miami Beach area is geographically isolated from the Florida mainland, the reliability of power supply systems and local transmission and distribution systems is critical. For this reason, the original transmission/ substation system serving Miami Beach was designed as a fully redWldant or si.ngle contingency system so that the loss of any single component will not result in an extended service interruption. Such a system provides redundant, backup facilities so that interrupted service can be restored in less than 1 minute. This single contingency design is costly and not current FPL practice. However, as stated in their report, FPL "will rebuild the substations serving Miami Beach in accordance with the original design." Using the single contingency design criteria, if a fault develops in the 138-kV submarine cable serving the south Miami Beach area, the remaining two 69-kV cables would not have sufficient capacity to serve the projected 1999 load of 258- MY A. This shortage will cause long extended outages within the service area Wltil the 138-kV submarine cable is repaired. TIus situation would severely impad system reliability and justifies the addition of transmission capacity to serve the area. Are overhead and underground versions of the proposed line the only alternatives? Are there other alternatives? FPL AlternatifJes FPL representatives said they have looked at various alternatives for providing additional transmission capadty for the southern area of Miami Beach. They have provided descriptions fur two overhead routes, one underground route, and one submarine route as. examples of feasible alternatives they considered. One of the overhead routes is the currently proposed route along Alton Road. The other overhead route is mostly along Dade Boulevard and Pine Tree Drive. Both of these routes can be can be considered one alternative, since the only difference between them is the line route. Cost wise, they are very similar. The underground route is the same ac; the proposed overhead route with minor variations. The submarine route goes from Venetian substation north through Sunset Lake and Sunset Lake Bay following the water's edge to 40th Street substation. FPL also considered other alternatives that were discarded for various reasons. The main ones being cost and scheduling. We asked FPL why they had chosen not to upgrade the existing 69-kV underground line. Their written response is that the new proposed line is the most efficient based on cost, capacity, reliability, and feasibility. Other Alternatives The alternatives described by FPL are limited to interconnecting the 40th Street substation and the Venetian substation. However, the goal is to provide additional power to the southern part of Miami Beach so that if a fault occurs on the existing 138- CITY OF MIAMI BEACH APRIL 9,1998 PAGE 8 OF 15 04/09/98 THU 16:23 FAX 407 895 6486 R M lOR LAN D 0 @009 kV cable the load can still be served without significant impact to service reliability. The following alternatives are all capable of satisfying future service requirements; · Upgrading existing 69-kV cable between 4lJth Street substation and Venetian substation. · Upgrading existing 69-kV underground/submarine cable from Miami substation to Miami Beach substation. · Install new underground/ submarine cable from Miramar substation (assuming it has sufficient capacity) to Venetian substation along Venetian Causeway. Evaluation of Alternatives The following listing of alternatives consolidates those considered by FPL and the additional ones listed above They are repeated and numbered here to simplify the Wscussion that follows. · Alternative No.1 This alternative is the proposed 1.8 miles of 69-kV, single concrete pole, overhead line with 954 kcmil ACSR/ A W phase conductors. Proposed route is mostly along Alton Road or along Dade Boulevard and Pine Tree Drive. · Alternative No.2 Construct a new underground, 69-kV line with three 2000- kcmil, copper cables in 3 - 6" conduits. T otalline length = 1.8 miles. Line route will be similar to the proposed overhead line along Alton Road. · Altenuztive No.3 Construct a new submarine, 69-kV line v.ith three 2000- kcmil, copper cables in 3 - 6" conduits. Line goes north from Venetian substation to SWlSet Lake then Sunset Lake Bay. Line will follow water running parallel to the shoreline in the bay and canal. Line then heads east along north side of 40th Street to 40th Street substation. Line length = 1.8 miles. · Alternative No.4 Replace existing 69-kV underground cable between 40th Street substation and Venetian substation with a double circuit, 69-kV, underground line each circuit consisting of three 2000 kcmil, copper cables in 3 - 6/1 conduits. Line to follow existing routing from 40th Street substation to Venetian substation. Line length = 20 miles. · Alternative No.5 Replace existing 69-kV underground/submarine cable between Miami substation and Miami &ach substation with double circuit, 69-kV, underground/submarine line each circuit consisting of three 2000 kcm.il, copper cables in 3 - 6" conduits. New line routed along same route as exiting line. line length = 3.7 miles. · Alternative No.6 Construct a new 69-kV, underground/submarine line with three 2000-kcmil, copper cables in 3 - 6" conduits. Line route to go south CITY OF MIAMI BEACH APRIL'. 19'8 PAGE 9 OF 15 04/09/98 THU 16:23 FAX 407 895 6486 R M lOR LAN D 0 ~010 from Miramar substation to 15th Street, east on 15th Street/Venetian Causeway to 17th Street in Miami Beach, continue east on 17th Street to West Avenue, north on West Avenue to Venetian substation. This alternative assumes Miramar substation has sufficient capacity to provide power to Venetian substation. Line length = 4.4 miles (1.7 miles underground cable on land and 2.7 miles submarine cable). Although cost and scheduling seem to be the main factors considered in the evaluation of the alternatives, there are additional tangible and intangible factors that should be considered. Intangible factors are those that cannot be meaningfully evaluared in monetary terms. Two such factors are consumers' interests and public relations. Tangible factors include cost and scheduling, but there are others such as reliability improvement, permitting, environmental impact, and electromagnetic field limitations. Our subjective evaluation of the six alternatives considered is presented in Table I on the following page. Each alternative is assigned a rating on a scale from 1 to 10 for each of the factors listed. A must value of 10 is assigned to the alternative or alternatives ranked highest for each evaluation factor. The other alternatives are then ranked in comparison to the highest ranked one. Each evaluation factor is also assigned a numerical weight that defines its relative importance with respect to the other factors. Weights range from 1 to 10 with the most important evaluation factor assigned a weight oflD. The estimated cost of each alternative is also included in the table but is not part of the subjective evaluation. The cost estimates show that Alternative No.1, the overhead line along Alton Road, is the least expensive. Alternative No.2 is the least expensive when compared to other underground and submarine cable Construction alternatives. Our estimates were prepared using information provided by contractors and vendors in the South Florida area. We also relied on Westem Area Power Administration's (W AP A) Conceotual Planning and Budget Cost Estimating Guide. The guide provides per mile costs for overhead and underground transmission line construction. Where necessary, old construction, material, and equipment prices were updated using the industry accepted Handy - Whitman Index of Public Utility Construction Costs published by Whitman. Requardt and Associates, LLP; Engineers - Consultants. In the evaluation section of Table-I, the evaluation factors listed are those considered most relevant to the purpose of this report. Reliability improvements is a factor that indicates the level of reliability that can be expected from the different line designs for each Alternative. It does not refer to the improvement in system reliability that would result from the implementation of each Alternative.

The proposed overhead line would be the least reliable type of construction of all the other alternatives. It is rated 4. Permitting is evaluated from the point of view of which alternative would require the least effort to obtain the required permits. Because of the environmentally sensitive areas within the Miami Beach city limits that any underground or submarine construction will require extensive pennitting from the FDEP and other state and local authorities. For this reason, Alternative No.1 is rated highest. It will require the lowest effort in securing the required permits since it will be located on public right-oi-way. Environmental impact refers to the permanent impact each alternative will make on the environment. The highest rating goes to the alternative that will have the lowest impact on the environment. Alternative No.2 will be installed underground and all the soil disturbance and construction problems associated with the initial construction of the line will disappear once the line is installed and the trench is backfilled. The overhead line, Alternative No.1, will leave a significant visual impact on the environment. Submarine construction can create a greater impact on the environment than an underground line because the sea, river, or lake bottom is disturbed during the installation of the cable. Electromagnetic fields, while not a new concern within the electric utility industry, have become more prominent public concern during the past 10 to 15 years. Typically, overhead distribution lines generate the strongest electric a.nd magnetic fields. The increased height of transmission line conductors reduces the strength of magnetic and electric fields they produce at ground level. Transmission lines usu~y carry lower currents so they produce weaker magnetic field than distribution lines. The State of Florida has established maximum allowable magnetic field strengths that can be produced by transmission lines at the edge of the right-of-way. However, those guidelines do not apply to 69-kV lines. Underground and submarine cables do not produce significant levels of electric or magnetic field strengths. The earth or water covering, the cable shielding and in some cases the metallic conduits mitigate any electric or magnetic fields produced by underground or submarine cables. Consumers' interest refers to the impact on home and property values resulting from the construction of each alternative. It also accounts for negative impact on public property as a result of constructing the new line. The alternatives resulting in the least amount of impact is Alternative No.2. It is a simple Ul)derground line requiring minimal excavation and will be completely out of site once installed. For this reason it is rated the highest of all the alternatives. The overhead line will result in the most impact to the consumers. In some cases overhead lines close to homes have decreased significantly their market values. Public relations refers to how the project will be accepted by the general public. Typically, overhead lines are the least accepted. In this case, Alternative No. 2 represents the least objectionable alternative and is ranked the highest CITY OF MIAMI BEACH APRIL 9,1998 PAGE 12 OF 15 04/09/98 THU 16:26 FAX 407 895 6486 R M lOR LAN D 0 ~013 Ease of maintenance relates to how quickly the line can be restored when the line has been damaged. While underground lines usually experiences less problems over their expected life, they are much more difficult to repair. Cable splices require more time to install and are more expensive. Locating a problem in an underground cable is much more complicated than with an overhead line. Overhead lines can be inspected visually and can be worked from a bucket truck parked on the side of the road. Therefor, Alternative No.1 is the highest rated with respect to maintenance. Accessibility is interrelated with ease of maintenance. Obviously overhead lines are more readily available than underground lines. For this reason, Alternative No. 1 is rated the highest with respect to this evaluation factor. The lowest rated alternatives are those involving submarine cables. Overall, Alternative No.2 is the highest Tated. It provides the additional reliability required causing the least impact to the environment. Are FPL's cost estimates reasonable? The cost estimates for the different alternatives discussed previously were determined based on independent information obtained from vendors and contractors serving the South Florida area. As explained previously, prices that were not current were brought up to date using the Handy - Whitman Index of Public Utility Construction Costs which is an industry accepted indexing service that provides a system for up dating or back dating construction costs. FPL's cost estimate for Alternative No.1 is $600,000. Our estimated cost for this alternative, as shown on Table I, is $674,303 which is 12% higher than FPL's estimate. The difference is pr~bably attributable to the differences in pricing infonnation. FPL has access to quantity pricing through their project estimating data base. The prices we obtained from vendors and contractors are off-the-sheif prices that tend to be higher. FPL's cost estimate for Alternative No.2 is 53,600,000. Our estimate for this Alternative is also shown on Table I as $4,048,012. The difference is also 12% and is due to the same reasons as discussed previously. We believe, FPL's cost estimates for the two alternatives are reasonable. Is the City required to pay the differential between overhead and underground construction? FPL's report explains that a single contingency design is costly and is not currently their standard design. They chose to make an exception and rebuild the substation.. serving Miami Beach in accordance with the fully redundant or single contingency original design. The report does not indicate why or how they arrived at such a decision. Similarly, the determination to build a the new 69-kV transmission line is also CITY OF MIAMI BEACH APRIL 9) 1998 PAGE 13 OF 15 04/09/98 THU 16:27 FAX 407 895 6486 R M lOR LAN D 0 I4J 014 based on single contingency design criteria - the loss of the 138-kV submarine cable. Otherwise, the new line is not required since the existing lines provide sufficient capacity for current load and projected future loads. In a similar way, the original design criteria fur the transmission system in Miami Beach was to place the lines underground, but for some reason, in this case, FPL chose not to follow the original design criteria. Placing transmission lines underground is also costly and not FPL's current standard design, but, except for the 1.3 mile section of 69- kV line from Deauville substation to Normandy Beach substation, all other transmission lines on Miami Beach are underground or submarine construction. Why did FPL choose to deviate from the original design in this case? Is FPL's in-service date reasonable? The original report prepared hy FPL stated that the new 69-kV line from 40th Street substation to Venetian substation had to be in-service by June I, 2000. However during the City Commission meeting on March 18,1998, FPL representatives expressed a high sense of urgency to begin designing and constructing ilie new line b~ause it had to be in-service by June 1, 1999. The discrepancy was explained by FPL's representatives during our March 24 meeting. FPL explained that the results of the original studies have been revised to reflect the results of a new load growth forecast based on more recent information. The new load growth forecast indicates the required completion date for the new transmission line i'i now June I, 1999. According to FPL, this change will require starting construction on the new line as soon as possible. F~r this reason they have attributed a high sense of urgency to this project. They anticipate a total project duxation of 18 months and stated in the Commission meeting that a thirty day delay in the start of line design and construction could delay the in-service date by the same amount of time. According to FPL, a thirty day delay could result in excessive and prolonged outages in the summer of 1999. This may be a moot point since the City Commission has delayed their approval of the project for thirty days to review the remaining unresolved issues. However, it may become a point of discussion at a later date and should be addressed at this time. Load growth forecasts are based on future load information obtained from permit applications and other such data submitted by property owners, developers and City staff. Through various statistical methods, those estimates of future loads are converted into a load growth forecast. Regardless of the accuracy of the forecasting tools used to develop the load growth forecast, the overall accuracy of the results cannot be very precise and certainly would not be accurate enough to pinpoint the requireu in-service date for the line to a less than thirty day window. While there is a sense of urgency associated with this project, the June 1, 1999, date may not be as firm as FPL indicates. Unless there are other more compelling reasons, CITY OF MIAMI BEACH APRIL 9, 1998 PAGE 14 01' l~ 04/09/98 THU 16:27 FAX 407 895 6486 R M lOR LAN D 0 ~015 that FPL has not provided to the City, it is not possible, based on norma1load growth forecasts, to determine the precise moment in the future when new or additional capacity must be available. There are typically a "best<ase" scenario and a "worst- case" scenario that define a range of time during which system modifications are required. A thirty day period is too short a time period and not a realistic interpretation of the results obtained from a load growth forecast. CONCLUSIONS AND RECOMMENDATIONS Our analysis indicates that to maintain a fully redundant (single contingency reliability) service to the southernmost area of Miami Beach, additional transmission capacity will be required. We have also concluded Ulat FPL is not required by any state agency, statute or rulings from the FPSC to place any new or replacement transmission or distnbution lines underground. On the other hand, at FPL' 5 discretion. it can elect to place new or replacement facilities underground at their expense. They have done this recently at other locations in the Miami Beach area. Our independent cost estimates confirm that the proposed overhead transmission line is the most cost effective alternative for providing the additional transmission capacity needed to maintain the single contingency reliability criteria in serving south Miami Beach. Furthermore, the proposed underground line alternative proposed by FPL is the least expensive of all the underground or submarine alternatives investigated. Since it is within FPL's discretion to place the new line underground a,nd all existing transmission lines within the Miami. Beach City limits are underground, we recommend the City formally request FPL to place the new 69-kV line underground at FPL'g sole expense to match the existing line design criteria and construl.1ion practices within the City.

Aguila tJC\~ First Assistant city AttoJiiey TO: SUBJECT: PROPOSED FPL TRANSMISSION SYSTEM UPGRADEIUNDERGROUND UTILITY LINE DATE: April 8, 1998 Pursuant to your request, this memorandum is provided pursuant to the ongoing negotiations between the City and FPL with regard to the installation of a new transmission line that will run between 41 st Street and the area of 20th Street and W est Avenue. While FPL is planning an overhead installation, the Administration has requested that this line be placed underground. Concurrent with these negotiations, the City-wide underground conversion of electric lines has also been an ongoing matter of discussion. FPL has advised the City that it is only required to implement the lowest cost alternative of the installation of lines. In the case of the ongoing negotiations for the aforestated new transmission line, an overhead installation is the less costly alternative; the City therefore would have to pay for the cost differential for the underground installation of this line. You requested that the Legal Department provide you with an opinion as to whether FPL is legally justified in seeking the least costly alternative and, additionally, whether the City can compel FPL to pay for the additional cost of undergrounding the proposed transmission line. My initial research has been based upon an overview of case law in the State of Florida, regulations promulgated by the Public Service Commission, as well as conversations with City Attorneys in other municipalities currently dealing with the underground utility issue including the City of Coral Gables, Sunny Isles, Jupiter, and Key Biscayne. In Florida Power Cor:poration v. Seminole Countv, 579 So.2d 105 (Fla. 1991), the Supreme Court of Florida held that the jurisdiction of the Public Service Commission to regulate rates and services of public utilities precluded the authority of cities and counties to require an electric utility to place its lines underground. In that case, FPC brought an action against Seminole County and the City of Lake Mary against the enforcement of ordinances which required it to underground its overhead power lines, which were along a right-of-way of road which was to widened. The case stated in pertinent part Thus, the Public Service Commission is vested with the authority to require conversion of distribution lines to underground where "feasible" if the Commission finds this to be "cost effective." Permitting cities or counties to unilaterally mandate the conversion of overhead lines to underground would clearly run contrary to the legislative intent that the Public Service Commission have regulatory authority over this subject. [Florida Power Cor:poration v. Seminole County at p. 108] The Florida Power Cor:poration case affirmed the jurisdiction of the Public Service Commission to regulate rates and services of public utilities, preempting the authority of the City and County to require an electric utility to place its lines underground. The case recognized that while the authority given to cities and counties in Florida is broad, both the constitution and the statutes recognize that cities and counties have no authority to act in areas that the legislature has preempted. See also, e.g., Art. VIII, S l(t), leg), 2(b), Fla. Const.; SI25.01, 166.021, Fla. Stat. (1989); Tribune Company v. Cannella, 458 So.2d 1075 (Fla. 1984), appeal dismissed subnom.; Deperte v. Tribune Company, 471 U.S. 1096, 105 S.Ct. 2315, 85 L.Ed.2d 835 (1985); Speer v. Olson, 367 So.2d 207 (Fla. 1978). In similar negotiations with city attorneys in other municipalities currently negotiating with FPL on the issue of conversation to underground utilities, FPL has consistently taken the position that the additional costs from overhead to underground must be borne by the governmental entity seeking the conversion. I have also reviewed the City's current Franchise Agreement with FPL and fmd no requirement mandating conversion of overhead utilities to underground utilities, nor is there an express provision as to the apportionment of cost for same to the utility company. Therefore it is my opinion that the issue of the additional cost from overhead to underground of the transmission system at issue here remains a point of negotiation between the City and FPL. At this time I find no legal authority which ~ould obligate FPL to pay for this additional cost. Should you have any questions or comments regarding the above, please do not hesitate to contact me.

They are as follows: Option 1 - FPL has advised that they will participate with the City in the financing of this project by loaning the funds to us at a competitive tax exempt interest rate. Based on our research FPL extended funds to the City of Jupiter in the amount of $1.2 million over a four year period at 3.75%. Option 2 - The City could propose a General Obligation Bond issue. This project along with other non-revenue generating public purpose projects prioritized from the CIP process could be packaged for an additional tax exempt general obligation bond issue. Option 3 - The City co.uld request a tax exempt loan from either the Sunshine State or Gulf Breeze municipal bond pools. Additionally, a special taxing District or Special Assessment Area was considered, however, the benefit of the increased capacity must be allocated to the properties that receive the benefit. As this transmission line increases the capacity for the City, it would be appear that the allocation of this benefit to specific properties would be most difficult. I would recommend that Options 1-3 be considered and the most cost effective method be selected based on the amount of funding required and the interest rates available to the City at the time the funding is required.
