Our solutions include solar energy generation in conjunction with other technologies. This can be a solar-plus-storage model to provide a non-wire alternative for a utility, or part of our ecodistrict offering, integrated with a district heating and cooling system and microgrid technologies, moving towards a zero-carbon solution.
Solar’s viability is demonstrated by the fact that in 2018 it provided 29% of new electricity generating capacity additions, with an average of 597 MW of residential solar alone added each quarter. Solar-plus-storage is expected to account for 7% of all distributed solar capacity in 2019, rising to 23% by 2024. A 4.5% year-on-year decrease in average turnkey installed cost, to below $3.00/W in Q4 2018 has helped.
Our regulatory affairs and analytics teams provide key support in the application of solar generation options. We scour local, state, and municipal regulations and incentives, including energy building codes, Renewable Portfolio Standard (RPS) and Clean Peak Standard (CPS) requirements, Renewable Energy Credit (REC) programs, next-generation Net Metering, Community Solar tariffs, and federal Investment Tax Credits (ITC). Optimizing solar economics amongst a suite of integrated on-site energy technologies often requires sophisticated analysis of tariff interactions and layered incentives on a territory-by-territory basis.
