The service provides estimates of energy cost and expenditures related to investments in energy efficiency or renewable energy systems. By calculating probable energy bills with and without those investments, it can help demonstrate cost savings and return on the resources invested. Calculations are based in part on utility services available and rates at a location, as well as electrical load profiles.
API methods support varying procedures for calculating probable electric power bills based on assumptions, including current utility rates, specified in a request. The API gives access to detailed calculations such as hourly load profile, total energy consumption over a period of time, and detailed line items expected in an electric service bill, among others. Methods can adapt and provide estimates based on only partial information.
