Technical Assistance to State Public Utility Commissions

Technical Assistance to State Public Utility Commissions


The State Technical Assistance to Public Utility Commissions (PUCs) program is part of the U.S. Department of Energy’s (DOE) Grid Modernization Initiative funded by the Office of Energy Efficiency & Renewable Energy’s Solar Energy Technologies Office as well as the Office of Electricity. The program is offered in conjunction with Lawrence Berkeley National Laboratory (LBNL), Pacific Northwest National Laboratory (PNNL), the National Renewable Energy Laboratory (NREL), Argonne National Laboratory (ANL) and Oak Ridge National Laboratory (ORNL). The goal of the program is to provide high-impact, in-depth technical assistance to help state regulators address a wide variety of challenges facing the electricity industry.  Many of the challenges are associated with rapid technological advancements, the emerging roles of both customers and third parties in the generation and management of electricity, the convergence of operations, markets, and planning across the bulk-power and distribution system domains, and considerations for addressing the climate crisis and enhancing the equity, affordability, security, and resilience of the electric grid.  This program augments and complements current technical assistance activities undertaken by various DOE program offices.

The competitively selected state PUCs awarded to receive technical assistance are as follows:
