Nuclear Power: A Hedge against Uncertain Gas and Carbon Prices?
研究了在自由化电力市场中,核电因燃料和碳价不确定性而具有被忽视的期权价值,但该价值随电价、气价和碳价相关性上升而锐减,质疑市场能否激励社会最优的多元化投资。
High fossil fuel prices have rekindled interest in nuclear power. This paper identifies specific characteristics making nuclear power unattractive to merchant generators in liberalized electricity markets, and argues that non-fossil fuel technologies have an overlooked ‘option value’ given fuel and carbon price uncertainty. Stochastic optimization estimates the company option value of keeping open the choice between nuclear and gas technologies. The merchant option value decreases sharply as the correlation between electricity, gas, and carbon prices rises, casting doubt on whether merchant investors have adequate incentives to choose socially efficient diversification in liberalized electricity markets.
