Description

The Defense Energy Support Center (DESC), in conjunction with the Naval Facilities Engineering Command-Atlantic Division, and the PNS, seek responses from Energy Service Providers (ESPs) concerning PNS's ultimate objective of reducing immediate and long-term energy costs. To obtain this result, the Government seeks ESP's to provide the necessary assistance to best posture the PNS load profile for competitive procurement of electric generation in the near future. ESP's are requested to provide a descriptive evaluation of the existing PNS load profiles and include what possible strategies could be imposed to assist in the furtherance of PNS position for the procurement of electric generation services in the near future and meet the objective of this RFI. ELECTRICAL SERVICE INFORMATION -- OBJECTIVES The anticipated changes in the power purchase process as well as current opportunities for electrical cost savings will provide the PNS with an opportunity to lower its overall electric costs. The following are the PNS objectives in the purchase of electricity and its related services: Achieve financial benefits by competitively purchasing power and creating economies of scale and more favorable kWh prices due to predictability of load patterns. Reduce administrative costs while providing improved accuracy and information by implementing more effective processes for billing, invoicing and payment for electric services. ELECTRIC PURCHASING & MANAGEMENT The ESP is requested to provide what types of Risk Management services are currently being provided or anticipated being supplied to your clients once you begin managing electric power purchases for them. The PNS is interested in hearing about innovative ways your firm has assisted your clients with exceptional power purchasing opportunities. Please provide several examples. Does your firm provide training to client facility managers regarding topics such as energy conservation, demand limiting and facility power distribution improvements? If so, then please describe your program. LOAD and GENERATION Central Maine Power has supplied the 15-minute kWh usage interval data, and this data is available upon request. Also available is an excel file with monthly graphs of 15 minute kW demand. Please be aware that the usage is that experienced by the Central Maine Power Meter only, and that the PNS has several onsite generation units that have been base loaded, and also used as peak shaving units in the past. Base loaded units, peak shaving units, and units associated with PSN heating requirements have all been run primarily in the past as a means to reduce the peak demand costs as well as save money via cogeneration. With the new Central Maine Power LGS-Subtrans -- TOU 3-phase rates, the demand charge has been reduced to $1.83/kW. It is imperative that you are fully aware of the onsite generation capability of the PNS, and we encourage you to consider options for PNS that would include the entire load required by PNS, as well as providing the PNS with an optimal strategy regarding when, and for how long they should self generate, within their restrictions. Appendix B explains the self-generation capabilities, and gives a description of approximately how and when these units have been used in the last year, as well as some restrictions that may be required. It should be noted that in addition to self generation opportunities, the PNS is interested in any curtailment program that would produce additional electricity cost savings from the reduction of electrical use during specific hours of the day or days of the year. Explain how PNS may utilize the facility load shedding capabilities to reduce electrical cost under a supply agreement. ALTERNATIVE PRICING & SERVICES Alternative methods may provide an opportunity for the ESP to develop an innovative price for PNS. Please propose any pricing strategy or terms that you believe may provide an overall lower cost advantage to PNS. Appendix A The Portsmouth Naval Shipyard Fact Sheet Portsmouth Naval Shipyard Mission Statement: The Portsmouth Naval Shipyard (PNS) is located about 50 miles north of Boston, Massachusetts at the southernmost tip of Maine. It is located on Seavy Island in the Piscataqua River connected by two bridges to Kittery, Maine and is across the harbor from Portsmouth, New Hampshire. PNS is currently under the jurisdiction of the State of Maine. PNS main base encompasses approximately 290 acres and 250 buildings. These buildings represent more than 3,000,000 square feet of space ranging from office buildings, to light and heavy industrial facilities, to a medical facility. Approximately 50 of these buildings are classified as ship overhaul/repair buildings. In addition, there are three active dry docks at the site that are capable of docking all active classes of submarines including the LOS ANGELES and TRIDENT Classes. Dry-dock No. 2 is a state-of-the-art submarine repair and overhaul-refueling complex with the capability of fully enclosing a submarine in a climate controlled facility. The core mission of PNS is the repair, overhaul, and repair of LOS ANGELES Class submarines and their components. Appendix b Description of Existing Electric service and equipment list for The Portsmouth Naval Shipyard Electric power to the PNS facility is supplied from Central Maine Power Co. (CMP). The facility is serviced by one account. Account # 449-008-6595-011 provides electric service under rate class LGS-Subtrans-TOU 3 Phase (Meter # AB03407580). Power is distributed to PNS at the sub transmission level (34.5 kV) from CMP's Bolt Hill Substation. The aerial 34.5 kV line enters a PNS owned and operated 34.5 kV to 13.2 kV single-source intertie substation. The demarcation point occurs upstream of the substation, with PNS owning a small section of the 34.5 kV sub-transmission line. The CMP metering point is located at the demarcation point. The 2000 calendar year purchased energy was 53,697 MWH with a 40.13 load factor. The peak billing demand in that period was 15.2 MW and occurred on 9/19/00 at 2:00 p.m. The Shipyard owns and operates three (3) double-extraction steam turbines located at the Central Power Plant. Their ratings and operational status are: ID# Desc. Manuf. Installed kW kVA TG-5 Steam Turbine Generator Turbodyne 1978 7500 9375 Status: In-service/peak shaving unit TG-6 Steam Turbine Generator Westing. 1943 3500 4375 Status: Permanently out of service TG-7 Steam Turbine Generator Westing. 1945 3500 4375 Status: In service. Economic dispatch unit. The Shipyard also operates an ESPC owned 5.2 MW gas turbine. This machine was placed in operation 12/00. Due to contractual obligations, this unit is intended to be base loaded at all times, minus two annual maintenance shutdowns. Note: The gas turbine efficiency is inversely proportional to ambient inlet temperature with power output ranging from 5.8 MW to 4.2 MW. ID# Desc. Manuf. Installed kW kVA TG-6 Gas Turbine Generator Solar 2000 5300 6625 Status: Base loaded for ESPC contractual obligation Current Operating Strategy is as follows: Solar Taurus The Solar Taurus 60 gas-fired turbine-generator operates at approximately 5.1 MW @ standard conditions. Operates base loaded. This unit is currently part of a third party contract, and any new optimization of run hours will be required to financially meet or exceed the payment stream guaranteed to the third party. This unit runs on natural gas only. This unit went on line in December 2000, thus the CMP data reflects this decrease in kWh usage due to this operating scenario. Westinghouse The Westinghouse 3.5 MW double automatic extraction steam turbine-generator, vintage 1942-43. Operates when shipyard hot water heating system is on-line and this is the major source of 5 PSIG extraction load. Historical operating period is to run this unit beginning the second week in November thru March. The unit is typically loaded at 3.5 MW. This unit is supplied by steam from a boiler that runs on either natural gas or number 2 fuel oil. As evident in the Central Maine Power interval data, there are times when it runs at less than 3.5 MW. This is done to maintain at least one MW on the CMP tie line. Selling power to the grid is currently not a viable option, but may be in the future. In the past, this turbine has been available on an "on-call" basis to take advantage of installed capacity savings paid by the utility during the summer months, when it is typically not operating with the exception of foul weather incidents. The new deregulated process has eliminated this installed capacity savings and the PNS desires to capitalize on methods to gain credit for their installed capacity. Turbodyne Turbodyne 7.5 MW double automatic extraction steam turbine-generator, vintage 1976-78. This unit operates primarily as a back up when the base loses CMP power, but it has operated in the past as a peak-shaving unit. The unit has also operated in the past on an "on-call" basis if the Westinghouse happened to be down, again to take advantage of installed capacity savings paid by the utility during the summer months. This unit is available for optimization. Restrictions All self generation equipment is primarily used for back-up, mission critical, power supply and that will always be it main purpose. In providing the PNS with an optimization scenario in order to reduce overall costs, please include strategies such as volunteered load curtailment, volunteered self generation when it can save PNS money, as well as turning off self generation in order to save money. The steam turbines, as with most steam generators, will require several hours notification as when to run, and the gas turbine needs a shorter time period for notification.
