Letha Tawney

Letha Tawney is the chair of the Oregon Public Utility Commission (PUC), the three-member independent body that regulates electricity, natural gas, and telecommunications rates in Oregon. On 10 June 2026 Tawney delayed Portland General Electric's (PGE) proposed 29% large-load electricity rate rise and a corresponding 1.3% residential bill cut to a decision no earlier than 7 July 2026, citing the need for staff to review approximately 200 pages of tariff updates. The PGE filing was the first utility in the United States to translate the Oregon POWER Act's cost-attribution framework into an actual tariff.

Tawney was appointed to the Oregon PUC and has chaired it through a period of significant load-growth pressure driven by data-centre expansion and electrification. Her decision to delay PGE's tariff does not reject it; no money has shifted, meaning neither the 29% large-load increase nor the residential reduction takes effect until the commission rules. The delay reflects the complexity of cost-attribution in large-load tariff design, where data-centre operators, their power suppliers, and residential customers each contest who bears network upgrade costs.

The Oregon POWER Act, which PGE's filing implements, is a national first: it requires utilities to attribute large-load infrastructure costs to the customers causing them. How the PUC rules on 7 July will set a legal and regulatory precedent watched by utility commissions across the United States.
