Solar-Plus-Storage: Fastest, Cheapest Way To
Solar-plus-storage''s biggest payoff may be keeping customer costs stable. That''s important considering Americans pay more than ever
The coupled photovoltaic-energy storage-charging station (PV-ES-CS) is an important approach of promoting the transition from fossil energy consumption to low-carbon energy use. However, the integrated charging station is underdeveloped. One of the key reasons for this is that there lacks the evaluation of its economic and environmental benefits.
Solar-plus-storage is solving demand growth by providing reliable power when the grid needs it most – during peak hours. Solar consistently generates electricity to charge batteries, which can discharge their power whenever it's needed, cheaper than a new gas turbine. Meanwhile new gas plants face massive hurdles to near-term growth.
The capacity optimization model of the integrated photovoltaic- energy storage-charging station was built. The case study bases on the data of 21 charging stations in Beijing. The construction of the integrated charging station shows the maximum economic and environment benefit in hospital and minimum in residential.
The economic and environmental benefits of the integrated charging station also markedly differ on different scales: with scale expansion, the rate of return on investment and the carbon dioxide emissions reduction first increase and then decrease.
