Modernizing utility regulation is essential to align utility actions with Washington’s established clean energy and building decarbonization goals. Utilities hold significant financial resources and technical expertise that could greatly accelerate clean buildings progress with the right regulatory structures in place. A central objective is to ensure that utilities invest in clean buildings and their distributed energy assets with the same commitment and consistency they bring to large, supply-side infrastructure. Massively expanding DERs and effectively integrating them as grid assets can defer distribution upgrades and reduce the need for new generation resources or transmission capacity. Particularly as electricity demand rises and large-scale generation and transmission development face long lead times, buildings and the resources they host become an increasingly critical part of a clean, reliable, and flexible grid. The actions in this section focus on three of the most promising avenues to establish a system in which utilities are a driving force of the clean buildings transition.
