How distributed energy resources will reshape the grid
Distributed energy resources (DERs) — including rooftop solar, batteries, EVs and responsive loads — are transforming the electricity system from a centralized model to a more decentralized, flexible network. This shift affects planning, operations and customer interaction with the grid.
Expected changes
- Greater flexibility: DERs enable demand-side solutions that balance supply and demand locally, reducing the need for some centralized resources.
- Two-way power flows: Networks will routinely handle bidirectional electricity flows, requiring smarter protection, visibility and controls.
- New market roles: Aggregators and virtual power plants will coordinate DERs to provide grid services and participate in markets.
Benefits and challenges
- Resilience and reliability: Local generation and storage can improve outage response and provide backup during emergencies.
- Complexity: Managing many distributed assets introduces operational and regulatory complexity that requires improved communication standards and data analytics.
- Cost impacts: DERs can defer infrastructure investments but also raise questions about fair cost distribution and rate design.
What to expect for consumers
- More options: Customers will have expanded choices for generating, storing and monetizing energy.
- Dynamic pricing: Time-varying rates and incentives will reward flexible consumption and participation in grid services.
- Enhanced services: DERs will enable new value propositions like resiliency packages, managed charging and community energy programs.
The grid of the future will be more decentralized, digital and interactive. Thoughtful policy, technological standards and collaborative planning are essential to realize DER benefits while ensuring reliability and equitable access.
