Endogenous formation of Renewable Energy Communities
研究了家庭加入可再生能源社区的驱动因素，发现市场电价上涨、价格波动加剧或政府激励增加会提高参与率，社区可帮助家庭对冲电价波动风险。
This paper explores what drives households to join a Renewable Energy Community (REC) and how these drivers jointly determine the community’s endogenous participation. We present a model in which each household decides whether to join the REC or to continue buying energy on the market. REC members receive a share of the clean energy generated collectively by the REC at no direct charge. In return, they incur installation and coordination costs that rise with membership, while benefiting from government incentives. We find that households belonging to a REC draw less energy from the conventional market and are therefore less dependent on it. Participation in the REC increases when average market prices rise, market price volatility increases, or funds devoted to incentives become more generous. Our results highlight the REC’s role as a risk-hedging mechanism against fluctuations in energy prices.
