Baselines and efficiency standards

CenterPoint Energy has designed the C&I Standard Offer Program to encourage electric energy efficiency improvements that go above and beyond the efficiency gains typically achieved in retrofit or replacement projects. Consequently, energy and demand savings credit is based only on reductions that exceed current state and federal minimum efficiency standards, wherever such standards apply. In cases where these standards do not exist, savings credit is based on improvements relative to a customer's energy use prior to participating in the program.

The federal and state equipment efficiency standards used in the C&I Standard Offer Program are available for downloading from the following table. Note that these standards are Adobe® PDF® documents, available for viewing and printing only with Adobe Acrobat Reader.®

For new construction projects, the C&I Standard Offer Program required the installation of equipment that is more efficient than is specified by code. The applicable baseline standard for all new construction measures is ASHREA/IESNA Standard 90.1-1999. Energy and demand savings for new construction measures are based on efficiency improvements beyond the minimum efficiency required by code.
