“…In the second stage, after daily demand and sunshinedetermined PV availability become known, each producer selects its daily electricity production, thereby determining the equilibrium market prices. Like many other studies of the electricity sector, we employ the Cournot conjecture to determine equilibrium quantities and prices in the second stage of the game, where electricity is sold simultaneously by all producers to meet market demand (Carpio and Pereira, 2007;Borenstein and Bushnell, 1999;Green, 1996Green, , 2004Newbery, 1998;Tishler and Woo, 2006;Puller, 2007;Smeers, 2005, 2007;Tishler et al, 2008;Bushnell et al, 2008). We show that the optimal solution is very sensitive to PV's sunshine-dependent availability and capital cost.…”
