In states across the nation, the electricity system is changing, presenting challenges and opportunities for the delivery of reliable, clean, and affordable power to America’s homes, businesses, and institutions. As variable renewable generation and distributed energy resources (DERs)—including energy efficiency, demand response, onsite generation, energy storage, and electric vehicles—grow, the management of electricity is becoming more complex.
Fortunately, advancing technologies open the prospect for more flexible management of building and facility energy loads to benefit occupants, owners, and the grid. The purpose of advancing Grid-interactive Efficient Buildings (GEBs) is to optimize energy management by utilizing sensors, analytics, and smart controls to best serve the needs of occupants while considering the grid and external conditions (such as peak loads and weather). Greater optimization of the significant energy demand and supply functions that buildings offer – on an automated basis – has far reaching electricity policy and regulatory implications for State Energy Offices, Public Utility Commissions, utilities, and building owners and investors. Flexible load management can:
- Lower costs, enhance resilience, and reduce emissions
- Reduce peak loads, moderate the ramping of demand, and provide grid services
- Enhance energy efficiency and integrate distributed and renewable energy resources.
The fundamental question that arise from this opportunity are:
- How can we optimize facility interactions with the grid?
- How can states fashion policies, programs, and regulations to advance such optimization through GEBs?
- What are the roles for states, facility owners and operators, utilities, product and service providers, and others?
To help states approach these questions, the National Association of State Energy Officials (NASEO) and the National Association of Regulatory Utility Commissioners (NARUC) established the NASEO-NARUC Grid-interactive Efficient Building Working Group, with the support of the U.S. Department of Energy (DOE) Building Technologies Office and the Pacific Northwest National Laboratory (PNNL).
Through the GEB Working Group, State Energy Officials and state utility regulators can explore GEB technologies and applications; identify opportunities and impediments (technical and non-technical); identify and express state priorities and interests; inform policy, planning, programs and regulation; consider unregulated electric sector investments and implications; and advance GEB road map and pilot options.
GEB Working Group activities include state interviews, webinars, and exchanges. Private sector and non-governmental organizations are also being engaged. A state GEB briefing paper and other resources have been and are being developed developed. The resources page also includes links to other NASEO, NARUC, and external papers, presentations, webinars, and other items. NASEO and NARUC are partnered with DOE and the National Laboratories to provide demand flexibility/GEB-related technical assistance (TA) to Working Group states; 2020-2021 TA focus areas include: state and public buildings, pilot projects, state and regional GEB potential, and valuation of GEB grid services.
