9 KW & Therm Use % kwh/yr Therms/yr Sq Ft

10 Energy Results (2008) Objective 50% reduction in energy use Results - 80% increase in building space (30,300 to 54,600 sq ft) 60% decrease in gas (2,265 to 900 Therms/mo.) 45% increase in electric (29,500 to 42,800 kwh/mo.) 65% increase in annual energy bill ($45K to $75K) 10

11 Recycling Results Objective 50% reduction in liquid waste 25% reduction in solid waste Result 99% reduction in liquid waste (10,000 gallons recycled or used) 50% reduction in solid waste to land fill (An annual reduction of 62 tons) 11

12 What s Next? Solid job reducing our use of natural gas. We need to reduce our use of electricity. Since 1997 cost of electricity has increased at a rate of 2.6%/year. Increasing pressure on the use of electricity given the proliferation of electronic devices Our focus to reduce consumption has been efficiency and conservation no power generation. We want to control expenses. Refine efficiency & conservation measures to save energy Generate electricity from renewable sources 12

13 Conservation/Efficiency (C/E) or Production? 2008 Established an Interim Electric Objective 20 by 2020 Consumption level 20,000 kw/month by 2020 (assuming no building additions) C/E Air Compressor Initiative ($27K) Reduced electric by 15% Annual savings $13,200 Return on Investment (ROI) 2.1 years Production from Wind or Solar ($45K systems) Wind offset electric by 2%; 50 yr ROI Solar offset electric by 2%; 50 yr ROI Indiana Office of Energy and Defense Development Grant 13

19 Hidden Incentive - SREC Solar Renewable Energy Credit SREC s are earned when we produce 1 MW = 1 SREC Sold on the open market monthly Market rate fluctuates based on demand Anywhere from $0 to $800 per SREC May go away without notice 19

20 Conservation/Efficiency or Production? Continuing to implement measures to conserve or be more efficient New technologies Further refinement of current initiatives Foster partnerships to exchange ideas Expanding solar grid Solar Energy Credits (SREC) generates additional income Planned expansion to 60+ kw by

27 The Value of Investment Assumptions: Size is based on 28 panels costing $40,000 Panels produce 840 kwh/month Electricity costs $.12/kWh Each SREC is reimbursed at a rate of $250/SREC Tax credit of 30% = $12,000 Excluded from the calculation: depreciation and grants Calculation without SREC 840 kwh x 12 months = 10,080 kwh x $.12 = $1,210/($40,000 - $12,000) = $1,210/$28,000 = 4.32% ROI is 23 years Calculation with SREC 10,080 kwh/1,000 = 10 SREC s 10 SREC s x $250 = $2,500 + $1,210 = $3,710 /($40,000 - $12,000) = $3,710/$28,000 = 13.25% ROI is 7.6 years (Note: 2.5% increase in electric rate reduces ROI by one year) 27

28 Energy Results (2013) Objective 50% reduction in energy use ( benchmark) Results - 80% increase in building space (30,300 to 54,600 sq ft) 68% decrease in gas (2,265 to 720 Therms/mo.) 17% decrease in electric (29,500 to 24,400 kwh/mo.) 9% decrease in annual energy bill ($45K to $41K) 28

29 Energy Results (2016) Objective 50% reduction in energy use ( benchmark) Results - 80% increase in building space (30,300 to 54,600 sq ft) 70% decrease in gas (2,265 to 685 Therms/mo.) 8% decrease in electric (29,500 to 27,200 kwh/mo.) 7% increase in annual energy bill ($45K to $48K) 29

30 What has changed in Power Genration? We have been paid $80,000 in SREC revenue. (11/11 03/17) SREC payout went from $250/SREC to $450/SREC on January 1, The price of solar panels has gone down. (30% - 40%) The efficiency of solar panels has gone up. (10% - 20%) 30

31 What s Next? Conservation/Efficiency or Production? Our initial 2020 solar panel goal completed in 2013 We are short of our goal to cut electric consumption by 50% from our 1998 benchmark Continue implementing measures to conserve and/or be more efficient Investigate emerging technologies Maintain current initiatives Foster partnerships to exchange ideas Continue to expand electric production capacity Implemented net metering in March 2017 Expanded solar array to 95kw in May 2017 (40% increase) 31

32 Revised Value of Investment Assumptions: Size is based on 28 panels costing $25,000 Panels produce 1,060 kwh/month Electricity costs $.12/kWh Each SREC is reimbursed at a rate of $450/SREC Tax credit of 30% = $7,500 Net metering allows a 10% reduction in electric consumption Excluded from the calculation: depreciation and grants Calculation without SREC & without net metering 1060 kwh x 12 months = 12,720 kwh x $.12 = $1,526/($25,000 - $7,500) = 8.7% ROI is 11.5 years Calculation without SREC & with net metering 1060 kwh x 12 months = 12,720 kwh x $.12 = $1,526 + $153 = $1,679/($25,000 - $7,500) = 9.6% ROI is 10.5 years Calculation with SREC & with net metering 12,720 kwh/1,000 = 12 SREC s 12 SREC s x $450 = $5,400 + $1,526 + $153 = $7,079/($25,000 - $7,500) = 40.4% ROI is 2.5 years (Note: 2.5% increase in electric rate reduces ROI by one year) 32
