1 Funding Efficient and Sustainable Energy for Wastewater Treatment Facilities Diane W. Duva, Office of Energy Demand May 6, 2015 Connecticut Department of Energy and Environmental Protection

2 Benefits of energy efficiency Energy efficiency is a valuable resource Reduces air pollutants and greenhouse gases Saves customers money Reduced operating costs = Opportunity for savings reinvestment in facility Reduces need for more power generation More efficient large scale consumers can help reduce grid strain. Creates jobs 3

3 Funding Sources Clean Water Fund Energy Savings Performance Contracts CT Energy Efficiency Fund 4

4 Clean Water State Revolving Fund (CWF) PRIORITY LIST: The following are reserves in the CWF. Reserves are utilized on a first come, first served basis. CWF Requirements: Agreement is between State and Municipality as defined by State Statute EPA requirement: Buy American for Iron & Steel Connecticut Department of Energy and Environmental Protection

5 Clean Water State Revolving Fund (CWF) Available Reserves with Energy / Green RESERVE FOR PLANNING PROJECTS (55% grant): Energy audits for any WWTP that has not already received a CWF agreement for a complete treatment plant upgrade. Assessment of the risk to existing wastewater infrastructure from climate change (rising sea levels and increased storm intensities and coastal flooding) and an evaluation of alternatives for remedial actions. CSO communities to study the effectiveness of incorporating green infrastructure technologies into CSO mitigation projects associated with the implementation of a CSO LTCP. Connecticut Department of Energy and Environmental Protection

6 Clean Water State Revolving Fund (CWF) RESERVE FOR CONSTRUCTION OF I/I REHABILITATION PROJECTS (20% grant): Projects will minimize sewage overflows resulting from surcharge, reduce hydraulic overloading and energy consumption, improve treatment efficiency, and provide reserve treatment capacity. RESERVE FOR PUMP STATION REHABILITATION PROJECTS (20% grant): For replacing aging infrastructure, reducing hydraulic overloading, incorporating energy efficiency equipment and providing emergency power. Connecticut Department of Energy and Environmental Protection

7 Clean Water State Revolving Fund (CWF) RESERVE FOR RESILIENCY PROJECTS (20% grant): PA requires wastewater improvement projects that may be affected by sea level rise to consider in the project s design ways to mitigate the impact of sea level rise. The PA modified Section 22a-478 of the CGS. This reserve was created in response to this law. The types of projects funded under this reserve shall include work at the treatment plant, a pump station or within the collection system. Connecticut Department of Energy and Environmental Protection

8 Clean Water State Revolving Fund (SRF) RESERVE FOR GREEN INFRASTRUCTURE: Treatment plant, pump station, and/or collection system improvement projects that incorporate cost-effective renewable energy components. (20% grant) Community demonstration projects of green infrastructure technologies to promote infiltration of stormwater into the ground in combined sewer overflow areas, for CSO communities that are working toward compliance with their CSO LTCP. (50% grant) Connecticut Department of Energy and Environmental Protection
