Joint WIEB, WIRAB, and CREPC Meeting ● Berkeley Lab is pleased to announce the release of a new report, “Reading the Tea Leaves: How Utilities in the West Are Managing Carbon Regulatory Risk in their Resource Plans,” prepared at the request of the Western Interstate Energy Board.

Joint WIEB, WIRAB, and CREPC Meeting ● Uncertainty in the nature and timing of future greenhouse gas regulations poses substantial financial risks for electric utility ratepayers and shareholders. Long-term resource planning provides a potential framework within which these risks can be systematically assessed and managed. In this study, we examine the current treatment of carbon regulatory risk through a comparative analysis of the most-recent long-term resource plans filed by fifteen major utilities in the Western U.S.
