The input methodologies require the Commission to publish estimates of the cost of capital at regular intervals for each type of service. Estimates of the cost of capital for information disclosure purposes are determined annually. Estimates of the cost of capital for price-quality regulation are used in setting prices so they are determined before each new regulatory period.
On this page you can find the determinations of the cost of capital made in accordance with the input methodologies determinations.
Previous cost of capital determinations can be found in the IMs archive.
