ESPC & Microgrids: Owner’s Representation Service

ESPC & Microgrids: Owner’s Representation Service

Following a competitive bid process completed by its member towns and cities, CCM has launched a new Owner’s Representation Service for Energy Saving Performance Contracting (ESPC) and Municipal Microgrid projects.

What is ESPC? back to top

ESPC is a partnership:

  • No-upfront-cost contracting method
  • An Energy Services Company (ESCo) implements Energy Conservation Measures (ECMs)
  • ESCo is paid during project construction from escrow account funded by municipal lease, bond, etc.
  • Once construction is completed, energy savings are used to repay lender over time
  • ESCo guarantees annual savings ≥ annual program costs for every year of the program

What is a microgrid? back to top

A microgrid is a local energy grid with control capability enabling it to disconnect from the traditional grid. The grid is the central power source that supplies power to a wide range of buildings and homes over a very large area. A microgrid can operate in both grid- connected or island mode.

A microgrid generally operates while connected to the grid, but in times of crisis, such as power outages and storms, or for any other reason, a microgrid can separate from the grid and operate on its own in what is known as island mode. A microgrid will use its own local energy generation that can be powered by renewable sources (solar panels, wind, hydro), fuel cells, batteries, or fossil fuels.

Municipalities and other program participants that wish to make their critical facilities more resilient through a microgrid may apply for grant funding to CT DEEP and may be eligible for financing offered through the Connecticut Green Bank.
