未来资源研究所：2025年高效输电的激励机制优化：价格上限规制的潜在作用研究报告（英文版）

A low-cost method for increasing transmission capacity is to use grid-enhancing technologies (GETs). Setting transmission rates on the basis of cost may lead transmission providers to choose to install lines at greater cost than GETs. Price cap regulation (PCR) adjusts rates over time on the basis of inflation and expected (but not actual) cost reductions, thus giving the regulated firm an incentive to reduce costs, such as by adopting GETs. Allowed rates are likely to eventually diverge from
