The Untapped Potential of Distributed Energy Resources
California is facing a critical juncture in its energy landscape. As the state pushes forward with ambitious climate goals, policymakers are grappling with the challenge of expanding the power grid to accommodate growing demand, while also keeping electricity affordable for consumers. Amid these challenges, experts warn that a crucial opportunity is being overlooked – the untapped potential of distributed energy resources (DERs) to help address the state’s energy affordability crisis.
The Rise of Distributed Energy
Distributed energy resources encompass a diverse array of technologies, from rooftop solar panels and home batteries to electric vehicles (EVs) and smart appliances. As the costs of these technologies continue to decline, they are becoming increasingly accessible to homeowners, businesses, and communities across California.
The growth of DERs presents a unique opportunity to alleviate strain on the state’s power grid. Unlike traditional, centralized power plants, DERs are distributed throughout the grid, often located near the point of consumption. This proximity can reduce the need for expensive grid upgrades and transmission infrastructure, translating to significant savings for consumers.
Unlocking the Grid Benefits of DERs
A recent study by the Brattle Group found that virtual power plants (VPPs) – coordinated networks of DERs that can shift energy use to avoid peak demand – could provide over 15% of California’s peak grid demand by 2035. This would amount to around $550 million in annual consumer savings, with $500 million flowing directly to DER owners to offset the costs of technologies like EVs and heat pumps.
Moreover, by tapping into these distributed resources, utilities and their customers could save an additional $50 million per year by 2035, as the cost of deploying DERs is typically lower than traditional grid investments. This represents a win-win scenario, where DERs can help reduce energy bills while also improving the overall efficiency and resilience of the power system.
Policy Challenges and Utility Reluctance
Despite these potential benefits, California has struggled to put the full weight of policy support behind DER programs. Pilot initiatives have faced budget cuts or outright cancellation, and efforts to establish statewide targets for DER deployment have failed to gain traction. This reluctance is partly driven by the way utilities are structured and regulated.
Utilities earn guaranteed rates of return on capital investments in traditional grid infrastructure, but not on alternatives like VPPs. Additionally, they are held responsible for failing to keep pace with growing power demand, making them wary of relying on decentralized assets owned by customers. This utility-centric mindset has contributed to the stalling of several bills aimed at boosting the role of DERs in combating rising grid costs.
Restoring the Value of Rooftop Solar
Another challenge facing the widespread adoption of DERs in California is the declining value of rooftop solar. Recent changes to the state’s net-metering policies have significantly reduced the compensation that solar customers receive, slowing the growth of the rooftop solar market. This poses a problem for VPP providers and advocates, who see rooftop solar as a crucial component in meeting the energy demands of households and businesses with EVs and heat pumps.
Efforts to restore more value to customer-owned solar during this year’s legislative session have had limited success, with only one bill, SB 1374, making it through. While the new rooftop solar regime does reward customers for adding batteries to store surplus solar power, solar and battery advocacy groups argue that these rewards have not counterbalanced the broader erosion of rooftop solar values.
The Need for a Holistic Approach
As California grapples with the challenge of ensuring affordable and reliable electricity, the integration of DERs must be a central part of the solution. Policymakers and regulators must work to create a regulatory environment that encourages utilities and customers to collaborate in realizing the grid benefits of these distributed resources.
This may require a rethinking of the traditional utility model, potentially moving towards a system where distribution system operators (DSOs) are responsible for planning and managing the grid, while allowing for a more diverse range of players to participate in providing grid services through DERs. By fostering a more dynamic and competitive market for distributed energy, California can unlock the full potential of these technologies to drive down energy costs and support the state’s clean energy transition.
Harnessing the Power of Distributed Energy
The rise of distributed energy resources presents a unique opportunity for California to address its energy affordability challenges while advancing its climate goals. By embracing the integration of DERs into the power grid, the state can leverage the growing number of customer-owned technologies to reduce reliance on costly grid upgrades and centralized power generation.
As Local Builder London highlights, the path forward requires a holistic approach that aligns the interests of utilities, regulators, and consumers. Policymakers must work to create a regulatory environment that encourages collaboration and innovation, while also restoring the value proposition for customer-owned technologies like rooftop solar.
By tapping into the potential of distributed energy, California can not only cut utility bills but also enhance the overall resilience and efficiency of its power system. As the state continues to grapple with the challenges of a rapidly evolving energy landscape, the time is ripe to harness the power of DERs and deliver tangible benefits to households and businesses across the state.
