3. Topics today: CERP in BRP  MA Energy Pilot  Energy Leaders Roundtable Group  In-Conduit Hydropower Project  MA Return-on-Investment Model Moving energy-saving projects forward

4. Water / Wastewater Treatment in MA  370 public facilities  $150M / year Impacts  1 billion kWhs  1 million tons (CO 2 )

5. MA Energy Management Pilot (2007 – 2010) Public  (7) Water & (7) Wastewater Facilities  MA Dept. of Environmental Protection  MA Executive Office of Energy / Environmental Affairs  MA Dept of Energy Resources  EPA New England  MA Renewable Energy Trust  UMass Amherst – Northeast CHP Center Private  Every Major Investor-Owned Electric & Gas Utility Non Profit  Consortium for Energy Efficiency

7. 14 Pilot Facilities: Recommendations Efficiency: Save $2M / Year Green Power: Save $1.7M / Year Massachusetts’ Energy Pilot (2007 – 2010)

8. ARRA – Green Infrastructure Recovery & Reinvestment: Clean Energy & the Environment Fully Implement Pilot & Other “Green” projects (7) Wastewater Plants: $ 34.8 M (7) Water Plants: $ 8.2M $ 43.0M (7) Others $ 23.1M Total $ 66.1M Jump-start “Green” projects: 20% of SRF ARRA

9. City of Pittsfield Wastewater Treatment Plant 1,584 kW solar PV CHP Upgrade Aeration Upgrade - Diffused Air w / Turbo Blowers Overall 90% reduction in electrical costs, saving $660,000 / yr

10. Greater Lawrence Sanitary District Wastewater Treatment Plant Install VFDs / Premium Efficiency Motors Operational, Aeration, Water System, Lighting Improvements Save ~$637,000 / yr in Electric Costs Sludge digester &HVAC improvements Save ~$350,000 / yr in Natural Gas Costs Est. Annual CO 2 Emission Reductions: 2,035 tons

11. Town of Chelmsford Crooked Spring Water Treatment Plant 485 kW solar PV Feasibility Study: UMass – Lowell Producing 500,000 kWh / year (41%) Saving $ 73,000 / yr (Electricity/ REC) Real Time power monitoring (plant / public) http://www.powerdash.com/systems/1000277/

12. Results: National Model  Facilities saving $5 million annually  10 Megawatts of Clean Energy installed  23,000 tons of GHG emission reductions / year

13. Mass Energy Leaders Roundtable (2010 – 2014)  Coalition of state, federal, community & energy efficiency providers  Each meeting has a technical presentation, a presentation from a water utility, a discussion on energy management planning, and a site visit.

14. Integrated Approach – To Encourage  Energy benchmarking  Energy audits  Renewable energy assessments  EPA Energy Management Plan – Do – Check - Act Model  Financial Assistance

21. Objective: To develop a Financial Assistance / Partnership Model using energy-saving projects that will generate positive cash flow for cities and towns that can be reinvested back into public drinking water and wastewater infrastructure. Goal: Return on Investment The Power of Positive Cash Flow

22. Bundling Energy-Saving Projects Cash Flow ($) = Revenues - Costs

23. Funding Sources

24. Reducing Operating Costs & Reinvesting in your Facility  Quantify energy & cost savings  Energy-savings can boost your bottom line & reduce your carbon footprint  Pay for wasted energy or reinvest it in your facility (people / equipment / assets)

25. 2014 DW & WW Clean Energy ‘Gap’ Grants through MA DOER o Partnership between MA DOER, Mass DEP & MA CEC o $1,700,000 in grant funding o Max grant $200,000 Timelines o Feb 26, 2014 – Grant Announcement o April 23, 2014 – Close of Applications June 3, 2014 – Grant Awards http://www.mass.gov/eea/grants-and-tech-assistance/guidance-technical-assistance/ agencies-and-divisions/doer/doer-procurements.html

26. 2014 DW & WW Clean Energy ‘Gap’ Grants through MA DOER ROI: $1.7 M gap grant  $11M of Projects

27. Projected Results: ‘Gap’ Funding  31 Energy-saving projects moving forward Energy efficiency & on-site clean energy generation 1,500 kW (CHP), 4 solar PV (497 kW), water-source heat pump  Approx. $1.2M in annual cost savings for facilities  Approx. 15,300,000 kWh in annual electricity savings or on-site power generation  Grant Awards: http://www.mass.gov/eea/pr-2014/water- facilities.html

29. In summary, Facilities can continue to pay their existing / rising energy bills or they can act on their identified energy-saving opportunities
