1 MASS SAVE ENERGY EFFICIENCY FUNDING Together we can use it wisely Bob Dvorchik Supervisor WMECO Commercial & Industrial Energy Conservation Programs

2 Mass Save Introduced 2010 Uniform conservation programs offered by all MA electric & gas utilities Common eligibility requirements & incentives Technical assistance just as valuable as incentives

3 Gas / Electric Integration One site analysis will identify both electric & gas conservation opportunities Where appropriate, one electric / gas incentive offer

4 Multi-Administrator Application

5 WMECO ENERGY CONSERVATION CASE STUDIES Examples of successful conservation projects WMECO partnership with our customers to increase efficiency & decrease energy costs Each qualified for Mass Save energy conservation incentive funding

6 Friendly s Ice Cream 15 Energy Efficiency Projects at production plant in Wilbraham Total savings of 7.7 million kwh valued at $750,000 each year New process refrigeration systems, motor controls, lighting

7 Friendly s Lighting Project 2,700 fixtures replaced in 60 days High performance T8 & T5 fluorescent Occupancy sensors Savings of 1.1 million kwh valued at $100,000 each year

8 Spiral Freezers Friendlys approached WMECO before buying two new production freezers WMECO funded efficiency upgrades Example: temperature automatically floats from -40 to -20 at end of daily production

9 Community Music School of Springfield Small Business direct install program Energy efficient lighting and lighting controls Annual energy savings of 69,900 kwh Savings of $6,800 per year

10 Yankee Candle South Deerfield Retail Displays Removed: 250 metal halide 70 watts each Installed: 350 LED 16 watts each Estimated energy savings of 40,600 kwh annually + 5 kw demand reduction Savings of $4,500 per year Other LED projects save additional $135,000 per year

11 BIG Y Supermarkets: Amherst, Greenfield, Springfield, Southampton & Pittsfield stores Night curtains for refrigerated cases High efficiency ECM replacement motors on refrigeration equipment Lighting upgrades Total estimated energy savings of 1,487,000 kwh annually kw demand reduction Savings of $150,000 per year

12 Unistress - Pittsfield Removed: 158 metal halide lighting 460 watts each Installed: 158 hi-bay T5 fluorescent fixtures with motion 234 watts each Estimated energy savings of 100,000 kwh annually Savings of $12,000 per year

13 Trident Alloys - Springfield Installed efficient electric induction furnace Estimated energy savings of 400,000 kwh annually Savings of $54,000 per year

15 Hager Brothers Farm Colrain Variable Frequency Drive on milk vacuum pump 32,000 kwh saved per year valued at $3,000 annually

16 CHP (Combined Heat & Power)

17 CHP (Combined Heat and Power) Also known as Cogeneration On site production of electricity and heat New efficiency program offering by MA electric efficiency program administrators

18 CHP (Combined Heat and Power) Conservation is super appropriate for everyone CHP is not excellent potential for specific situations only

19 What makes a good CHP candidate? Year round thermal load Must have a need for hot water or steam all summer This hot water or steam must have an economic value to you

20 CHP Qualification Process Full year hourly analysis of existing thermal & electric load Projects must pass Mass Save cost / benefit test Different than a customer payback analysis CHP will increase your annual gas use

21 Typical CHP equipment 25 kw to 2,000 kw -Internal Combustion Engine Similar to truck or marine engines Hot water recovery F 2,000 kw and higher Combustion Turbines (jet engines) Recover heat from hot exhaust Generates steam Under 25 kw Micro CHP -Small engines or micro turbines Relatively new technology

22 CHP Incentives Analysis 50% of cost of a qualified analysis CHP Implementation Projects up to 150 kw: $750/kW Projects over 150 kw: Negotiated incentive
