Table of Contents large, complex energy conservation, and energy security projects for the federal government, and municipal -scale street lighting projects incorporating smart city controls O&M After an energy efficiency or renewable energy project is completed, we often provide ongoing O&M services under multi -year contracts. These services offer end -to -end technical guidance and include operating, maintaining, and repairing facility energy systems, such as boilers, chillers, and building controls, as well as central power and small- scale plants. For larger projects, we frequently maintain staff on -site to perform these services. In addition to providing O&M services for our own projects, we also provide similar services on projects we did not construct for various customers. Ameresco-owned Energy Assets Ameresco-owned energy assets are small-scale power plants that we develop, design, construct, finance and own/operate and are included in our consolidated balance sheets. These assets may sell electricity, heat, cooling, processed biogas, or renewable biomethane fuel under short -or long-term contracts. We also offer Energy as a Service ("EaaS"), where we design, construct, finance and own/operate various energy conservation measures on a customer's site and sell them the output or availability of these items under a short -or long-term contract. We have constructed and are currently developing, designing, and constructing a wide range of renewable energy plants using: • biogas (generated from landfills, wastewater treatment plants, and the agricultural sector) • advanced biofiels • biomass and other bio-derived fuels • solar PV • wind and hydro sources of energy • battery storage Most of our renewable energy assets to date have involved the generation and sale of: • electricity from solar PV or battery storage • electricity, thermal, renewable fuel, or biomethane using biogas as a feedstock In the case of our biogas-fueled projects, we purchase biogas that otherwise would be combusted or vented, process it, and either use it as a renewable fuel source in our energy plants to produce and sell electricity and/or thermal, or sell it as a renewable fuel source to a third party. We also design and build and operate and maintain facilities that process biogas into biomethane (or renewable natural gas) that can be transported, primarily through the nation's natural gas pipeline grid or in some cases through tanker trucks and sold to third parties. The rights to use the site for the plant and the purchase of raw feedstock fuel for the plant are also obtained by us under long-term agreements with terms at least as long as the associated output supply agreement. Our supply agreements typically provide for fixed prices or prices that escalate at a fixed rate or vary based on a market benchmark. See "We may assume responsibility under customer contracts for factors outside our control, including, in connection with some customer projects, the risk that fuel prices will increase" in Item IA, Risk Factors. As of December 31, 2023, we owned and operated 185 small-scale renewable energy plants including solar PV installations which generate electricity or deliver renewable gas fuel with a combined capacity of approximately 508 megawatt equivalents ("MWe") and have energy assets in development and construction with a combined capacity of approximately 717 MWe, which includes 48 MWe attributable to a non -controlling interest.
