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 Goal: Return on Investment

2014 DW & WW Clean Energy ‘Gap’ Grants through MA DOER
ROI: $1.7 M gap grant $11M of Projects
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
In summary,
Facilities can continue to pay their existing / rising energy bills
or they can act on their identified energy-saving
opportunities
Thank you!
