Commercial Building Efficiency Program

Incentives available for efficiency improvements

We offer support to help commercial customers improve building performance and reduce energy costs.

Our Commercial Building Efficiency Program is designed to help current electric and gas customers with buildings between 50,000 and 1 million square feet.

As part of this program, we help pay for consulting services that identify ways to improve efficiency. We also offer incentives based on verified energy savings and emissions reductions.

Total incentives cannot exceed 50% of the project cost and vary based on total energy savings.

We accept applications year-round, but we encourage you to apply early. Funds are limited and are awarded on a first-come, first-served basis. Those who apply after Nov. 15 are waitlisted until the following year.

Program tracks

Depending on your building or the scope of your renovation project, we offer two options.

“”

Energy Design Assistance (EDA)

Energy Design Assistance involves working with a team to improve building efficiency through design, equipment and proper technology configuration.

This is for new construction or major renovations (Alteration Level 3 or change of occupancy).

  • We pay 100% of consulting costs.
  • Consultants support your design team with strategies for energy efficiency, greenhouse gas reduction, and above IECC code compliance.

Retro-Commissioning (RCx)

Retro-Commissioning involves commissioning a building after it’s been occupied. Energy engineers complete the commissioning process to identify opportunities to save energy.

For existing buildings.

  • We pay 75% of RCx service costs.
  • Customers pay 25%.

This service identifies energy‑saving opportunities, system optimization and operational improvements.
