Commercial and Industrial Demand Response Under Mandatory Time‐of‐Use Electricity Pricing
利用自然实验评估了强制分时电价对商业和工业企业用电的影响，发现整体用电、高峰用电和峰值负荷变化微乎其微，经济效率未提升，账单和波动性变化也很小。
This paper is the first to evaluate the impact of a large‐scale field deployment of mandatory time‐of‐use ( TOU ) pricing on the energy use of commercial and industrial firms. The regulation imposes higher prices during hours when electricity is generally more expensive to produce. We exploit a natural experiment that arises from the rules governing the program to present evidence that TOU pricing induced negligible change in overall usage, peak usage and peak load. As such, economic efficiency was not increased. Bill levels and volatility exhibit minor shifts, suggesting that concerns about increased expenditure and customer risk exposure have been overstated.
