1 AGENDA ITEM B5 DATE: October 1, 2012 TO: Gerald J. Seeber, General Manager FROM: Charles H. Carden, Chief Operating Officer SUBJECT: Energy Management Program Status Report SUMMARY: The attached report details the on-going activities being implemented within the agency s Energy Management Program. RECOMMENDATION: Receive Status Report. DISCUSSION: A programmatic approach to reduce energy use and take advantage of emerging technology and other opportunities is a top priority for the Agency. The attached Status Report provides a summary of on-going activities and projects related to the Agency s Energy Management Program. BACKGROUND: Substantial energy is consumed by Tampa Bay Water in providing water to its customers over a 2,000-square-mile service area. Water provided by the Agency is ondemand; that is, Tampa Bay Water does not control demand, but rather responds to its Member Governments demand for water. Commercial power is purchased from three commercial entities under multiple rates. Approximately 99% of Tampa Bay Water s energy costs are related to pumping, treating, and distributing drinking water from three different types of water sources.

2 Energy Management Program October 1, 2012 ENERGY MANAGEMENT PROGRAM ROADMAP Stafff has developed a Roadmap to implement the Agency s Energy Management Program. The Roadmap was reported to the Board during the October 17, 2011 Board meeting. The Roadmap: Aligns with the Agency s overall Strategic Plan. Identifies elements of technology and energy infrastructure to enhance financial stability andd sustainability of Tampa Bay Water s operations. Identifies gap/key projects necessary to bridge or connect on-going and planned capital projects with the steps and goals of the Energy Management Program Roadmap. Table 1 lists on-going gap/key projects and other program activities and their status. A full description of the activities is included in the Program s Roadmap report.

Developed reporting engine for the Energy Consumption Manager for staff and stakeholders to query, view, export and summarize electricity consumption expenditures and compare to water production at all facilities. Developed a tracking option of energy-related capital projects to compare baseline versus actual energy consumption and calculate percentage energy savings. Standard Specifications have been reviewed for compliance with the latest energy efficiency standards. Received draft memorandum summarizing review of Standard Specifications. Finalized Technical Memorandum. Next Steps Incorporate recommendations. Inventory of transformers is part of the Renewal & Replacement Program s efforts. Next Steps Complete inventory. Evaluate efficiency of transformers. Determine if replacement is needed. Additional Free Energy Audits from Tampa Bay Water s commercial power providers will be pursued on applicable facilities. These will be reported in Table 2. Staff is currently evaluating procurement options for industrial/investment grade audits (i.e. at a cost) for Page 2 of 10

Five facilities accounts tariffs changes were recommended for an estimated annual savings of $9,000 based on FY 2011 power costs. Changes to tariffs have been made. Tampa Electric (TECO) has reviewed the rates. Two facilities accounts tariffs changes were recommended for an estimated annual savings of $3,000 based on the previous 12 months of power costs. Changes to tariffs have been made. Staff will pursue commercial power providers rebates in a project by project basis. Staff will participate in the Progress Energy Backup Generator Program at the South Pasco and Starkey wellfields. Staff is currently following Federal and State legislation for energy projects funding. Page 3 of 10

5 REBATES & INCENTIVE PROGRAMS TECO s Commercial Demand Response Program On December 2007 the Board authorized Tampa Bay Water to enter into an agreement with Tampa Electric s (TECO) Commercial Demand Response Program provider EnerNOC. The Program helps manages peak demand to reduce summer and winter electricity demand peaks. Tampa Bay Water earns revenue in a quarterly basis by agreeing to reduce electricity consumption when TECO calls for a demand response event, i.e. the reduction of energy usage to lower peak demand. One means of accomplishing electricity reductions is through emergency backup generation. The following bulleted items are general program rules for emergency backup generation. Table 2: Commercial Demand Response Program Fiscal Year Revenue ($) 2008 $60, $143, $146, $189, (To ) $94,524 TOTAL ( To ) $587, kw or more of demand reduction available Thirty minute notification prior to reduction Reduction events may occur on non-holiday business days between 7:00 AM and 7:00 PM Reduction events may last from one to eight hours Reduction events are limited to 88 hours during a calendar year EnerNOC assumes all risk for non-performance Table 2 Provides a summary of revenue generated through this program by Fiscal Year.

6 FREE ENERGY AUDITS PROGRAM Staff has completed a Free Energy Audits Pilot Program to understand the free energy audits available from the Agency s three commercial power providers. Staff pursued this on a pilot basis to better quantify the costs and benefits involved in the audits recommendations. Table 3 includes a list of the facilities and their status. Based on the Energy Roadmap recommendations, Staff will pursue additional Free Energy Audits in selected facilities and Investment Grade Energy Audits (at a cost) in selected facilities during FY 2012 through FY Commercial Power Provider Progress Energy Facility Clearwater Admin Building South Pasco Wellfield Audit October 8, 2010 December 2012 Table 3: Free Energy Audits Status Report November 22, 2010 Recommendations 1.

8 CAPITAL IMPROVEMENT PROGRAM PROJECTS Staff continues planning, design and construction of energy savings-related capital projects. Listed in the tables below are completed and on-going projects, a brief description, and their current status. Staff has identified baseline energy use and cost for some of the projects and is currently collecting data in others, if applicable. Once projects are complete and fully operational and a year of energy use and cost data is collected, Staff will report percentage (%) of energy reduction achieved by the project. Table 4 includes projects for Tampa Bay Water s non-water production facilities, such as buildings; Table 5 includes projects associated with water production facilities; and Table 6 includes alternative/renewable energy projects.
