Abstract
Regulation is often thought to discourage innovation. This problem is not evidenced by electric utility behavior up through the mid-1970s, during which time utilities adopted various new generation technologies. However, retrospective “prudence” reviews, common since the 1980s, may discourage utilities from investing in promising but risky new technologies. When innovative technologies have lower expected costs but greater cost variance than conventional technologies, the threat of hindsight review may cause a utility to switch from an innovative technology to a more costly conventional one, and may cause underinvestment. Profit-sharing schemes, properly designed, can promote efficient levels of investment in innovative technologies.
