Town of Fairfield Energy Management: Electricity Since 1996 Fairfield has achieved the following in the 45 buildings it manages: 39% decrease in electricity purchased 94% reduction in fuel oil use Total energy expenditures did not decrease: 2.5% increase in total energy expenditures

Town of Fairfield Energy Management: Electricity The Town has reduced building electric consumption in 12 larger buildings, from 3,460,000kwh to 2,178,000kwh, by 37% in That reduction of 1,282,000kwh translates into $192,000 avoided expenditures this year.

Town of Fairfield Energy Management: Electricity Of the other 33 buildings, there was a savings of 308,000kwh and $48,000. In summary, Fairfield cut 1,590,000kwh of use, a 39%, reduction and saved $238,000

Town of Fairfield Energy Management: Electricity However, Fairfield added substantial new electric use requirements during this period, including: – Desk top computers – Power to the marina docks – Three private benefit facilities – Three air conditioning upgrades

Town of Fairfield Energy Management: Electricity Eleven (11) new buildings were constructed and two (2) additions, totaling 183,979 square feet were also added during this time frame. That is a 58% increase in total building square footage, taking the total from 314,524 to 498,500 These changes added $177,000 and 885,000kwh

Town of Fairfield Energy Management: Electricity To summarize : – Fairfield cut 1,590,000kwh of use, a 39%,reduction and saved $238,000 – The Town added 1,699,000kwh of new use and $263,000 in new costs – The price for electricity also rose from 10.9c/kwh to 15.5c/kwh-- by 42% – Thus Fairfield paid $837,000 for almost the same amount of power it bought for $448,000 in 1996

Town of Fairfield Energy Management: Heat Fairfield has switched from a heating fuel dependent Town to a natural gas or dual fuel dependent Town

Town of Fairfield Energy Management: Heat Heating Fuel Cost/ gal$0.70/gal$3.10/gal343% Total Gals388,000gal16,647gal(371,353) gal Total Cost$271,767$51,605($220,000)

Town of Fairfield Energy Management: Heat Natural Gas Cost /ccf$0.90$1.2336% Total ccfs39,526ccf228,347188,821 Total cost$36,000$281,000$245,000

Town of Fairfield Energy Management: Heat The result is a $10,000 savings in the overall cost of heat However, that includes the cost to heat over 180,000sf of new building space In does not include the avoided cost of the purchase of 370,000gal of heating fuel After the replacement cost of natural gas is calculated the avoided cost is over $900,000 in 2014

Town of Fairfield Energy Management: Get the Facts Categorize your buildings by: 1.KWH use 2.KW use 3.Size 4.Age (30 years or older always need work) 5.Hours of use 6.Seasonality

Town of Fairfield Energy Management: Electricity Determine which buildings use the most electricity and how the electricity is being used There are four (4) broad categories: Lighting –up to 50% of load Air conditioning (cooling)—8-23% Plug-ins, such as computers, soda machines, etc –5-20% Machinery (e.g.,at the Water Pollution Control Facility)---up to 55%

Town of Fairfield Energy Management: Heat Wherever possible convert from heating fuel to natural gas Consider solar hot water The savings are huge in: – Dollars – Air emissions, and – MMBTUs

Town of Fairfield Energy Management: Green Power 60kw natural gas trigeneration facility is installed in Police Department – Total cost paid by AARA grant – Produces 475,000kwh and – 16,000ccf avoided natural gas purchase – $50,000 savings

Town of Fairfield Energy Management: Green Power ZREC program—During the first two years of the program Fairfield received 10 PV awards – One large project for 1.0megawatts – Nine small projects for 850 kw We are submitting another large ZREC for 1.0megawatt next month Over 20 years the guaranteed savings are over $3,100,000

Town of Fairfield Energy Management: Water Pollution Control Facility (WPCF) I treat the WPCF as almost separate from the rest of the Town It is responsible over 40% of the electricity the Town uses It must operate 24 hours a day, 365 days a year Environmentally, it produces significant gas emissions, water discharges and solids all of which must be treated, using electricity

Town of Fairfield Energy Management: WPCF The goals: Reduce consumption Increase the use of Green Energy Reduce, or at least control costs, and Minimize environmental negatives

Town of Fairfield Energy Management: WPCF In 1995 Fairfield signed a DEP consent order for the WPCF $35,000,000 upgrade 100% Clean Water Fund Loan and Grant Hard sell to taxpayers

Town of Fairfield Energy Management: WPCF Received $135,000 incentives from UI Energy Opportunities Installed highest commercially available, energy efficient equipment Installed VFDs wherever possible Installed highest power factor equipment Result 1,350,000kwh and $210,00 saved annually

Town of Fairfield Energy Management: WPCF As part of a WPCF upgrade Fairfield 1.Installed a 200kw fuel cell with a 75% grant from CEF 2.Installed a 32kw photovoltaic system with another 75% CEF grant 3.Installed 360kw of gas fired microturbines

Town of Fairfield Energy Management: WPCF Produces 2,700,000kwh annually Savings $400,000 this year That is a payback of 3.4years Savings would have been higher, but fuel cell died after 5 years However 2,725,000kwh were added by the upgrade

Town of Fairfield Energy Management: WPCF A 100kw combined heat and power plant is being proposed that will produce about 800,000kwh and save $125,000 A UI funded energy and process audit is nearing completion This will suggest numerous other energy savings An “energy dashboard “ is installed that will measure power consumption by every piece of equipment to help control costs

Town of Fairfield Energy Management: The Process An energy consultant is critical for success Must be familiar with UI or CL&P s programs Must be familiar with State programs Must be able to research and critique new technologies Must have relationships with the best contractors for installation Fairfield selected Earth Corps Energy Services

Town of Fairfield Energy Management: The Process Choose an energy consultant Perform energy audits Create a long-term comprehensive plan Utilize the CL&P and UI energy savings programs Utilize whatever state or federal grants are available, especially DEEP and CEFIA Seek LREC and ZREC funding

Town of Fairfield Energy Management: The Process Consider performance contracting – Fairfield carried out a successful $7,000,000 performance contract with JCI over 10 years – Used municipal bonds because they are cheaper – Installed dual fuel – Lighting, HVAC, combined heat and power – Building controls system – Automated building managed maintenance plan – Indoor air quality stressed – Maintenance staff trained

Town of Fairfield Energy Management: The Process The leaders of your organization will consistently support the efforts, whether political, governmental or private sector, and Success breeds success.

Town of Fairfield Energy Management: The Future Technology is constantly improving and becoming more cost effective The consultant must constantly analyze the results and Seek funding aid Fairfield only pays the consultant if it is successful in receiving aid for the Town

Town of Fairfield Energy Management: The Future The largest technology improvements commercially available during the last two years on an affordable basis include: 1.LED and new fluorescent lighting 2.Plug power controls 3.Wireless formats for controls 4.Open protocol computer equipment 5.Ductless heating and cooling equipment

Town of Fairfield Energy Management: The Future 5. Solar hot water systems, for heat as well as hot water 6. Computerized, automated controls for lighting, heating and air cooling on a room by room basis or machine by machine basis

Town of Fairfield Energy Management: Summary Fairfield has carried out energy conservation measures in 18 of its top 20 electric consumers We have installed green power in 13 of these buildings Are planning to finish that list in both categories over the next 3 years

Town of Fairfield Energy Management: Summary We have installed the wireless building control system in 5 buildings and are planning to install it in 5 others LED and advanced fluorescent lights are now in 9 locations We have also put solar hot water in 2 of the buildings and are planning 3 other instalations

Town of Fairfield Energy Management: The Process LESSONS LEARNED The project leader must assume ownership The elected officials must buy in early The building managers must buy in early Appropriate the necessary funding early Emphasize that it is a long term, continuous improvement program

Town of Fairfield Energy Management: The Process Your champion must make a logical case : that energy conservation and the use of green power : 1.Uses commercial technology 2.Can save the taxpayer money 3. benefits both the environment and public health 4.while still allowing the private sector a profit,

Town of Fairfield Energy Management: The Process The leaders of your organization will consistently support the efforts, whether political, governmental or private sector, and Success breeds success.
