Drinking Water and Wastewater Facilities An Innovative Partnership:

1. Drinking Water and Wastewater Facilities An Innovative Partnership: The Massachusetts Department of Environmental Protection The Massachusetts Department of Energy Resources The Massachusetts Clean Energy Center Michael DiBara, MassDEP 30th Annual International Conference on Soils, Sediments, Water, and Energy October 21, 2014

2. Clean Energy Results Program • Launched in November, 2011 • MassDEP, DOER and CEC partnership • To advance environmental protection by promoting the development of renewable energy and energy efficiency projects in Massachusetts Barnstable Water Pollution Control Facility 819 kW

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 (CO2)

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

8. ARRA – Green Infrastructure Recovery & Reinvestment: Clean Energy & the Environment Jump-start “Green”projects: 20% of SRF ARRA • 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

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

10. Greater Lawrence Sanitary DistrictWastewater 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 CO2 Emission Reductions: 2,035 tons

11. Town of ChelmsfordCrooked Spring Water Treatment Plant • 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/ 485 kW solar PV

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.

20. Pittsfield Water - Coltsville Flow Control Station Project Slide courtesy of AECOM (D. Gove) • Project to replace old flow control station • 2 to 14 mgd flows w/ ~60 psi pressure reduction • $3 million construction • 62 kW Cornell hydro turbine • Revenue generated: • ~$14,000 sale of power • ~10,000 Class I REC’s

21. Goal: Return on Investment The Power of Positive Cash Flow 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.

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

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 • GrantAwards: 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
