Segment Reporting [Abstract]  
Our reportable segments for the three months ended March 31, 2021 are U.S. Regions, U.S. Federal, Canada and Non-Solar Distributed Generation (“Non-Solar DG”). We changed the structure of our internal organization and our U.S. Regions segment now includes our U.S.-based enterprise energy management services previously included in our “All Other” segment. As a result, previously reported amounts have been restated for comparative purposes.
Our U.S. Regions, U.S. Federal and Canada segments offer energy efficiency products and services which include the design, engineering and installation of equipment and other measures to improve the efficiency and control the operation of a facility’s energy infrastructure, renewable energy solutions and services and the development and construction of small-scale plants that Ameresco owns or develops for customers that produce electricity, gas, heat or cooling from renewable sources of energy and O&M services.
Our Non-Solar DG segment sells electricity, processed renewable gas fuel, heat or cooling, produced from renewable sources of energy, other than solar, and generated by small-scale plants that we own and O&M services for customer-owned small-scale plants.
The “All Other” category includes enterprise energy management services, other than the U.S.-based portion; consulting services, energy efficiency products and services outside of the U.S. and Canada; and the sale of solar PV energy products and systems which we refer to as integrated-PV.
These segments do not include results of other activities, such as corporate operating expenses not specifically allocated to the segments. Certain reportable segments are an aggregation of operating segments.
The accounting policies are the same as those described in the summary of significant accounting policies in Note 2 included in our 2020 Form 10-K.
The table below presents our business segment information recast for the prior-year period and a reconciliation to the condensed consolidated financial statements:
