The U.S. electric grid is in the midst of transformational change. Originally designed to transport power from remote power plants to end-use customers, our centralized grid is being challenged by new technologies. Rapidly dropping costs and technological advancements have made distributed energy resources (DER) — such as local renewables, energy storage, demand response, and energy efficiency — increasingly cost-effective solutions to meet electric system needs. Yet, few states are actively planning their distribution grids to capitalize on the growing value DER provide.
Distribution Resources Planning (DRP) establishes a comprehensive and transparent framework designed to improve distribution system planning, operations, and investment. It seeks to optimize utilization of existing electricity grid assets and new DER resources to modernize the grid while minimizing costs for ratepayers.
Building on its work driving California’s nation-leading DRP process, the Clean Coalition is now supporting the adoption of this vital policy in other states across the country.
DRP is a foundational policy for modernizing the grid to provide cleaner, more affordable, and more resilient power. An effective DRP effort should result in the following outcomes:
- Hosting capacity analysis: A proactive assessment of the existing distribution grid to understand at what locations capacity exists to accommodate new DER, which makes interconnection of these resources quicker and cheaper. Grid maps, with details on available capacity down to the circuit level, are made publicly available and regularly updated.
- Methodology to value DER: A method determined through a stakeholder process to assess the full value of DER to the utility and to the grid, with recognition that the value will likely vary depending on the location of a resource.
- Substation-level demonstration projects: Substation-level pilot projects, proposed by utilities and approved by regulators, that deploy DER to achieve immediate ratepayer savings when compared to conventional investments in centralized generation and grid upgrades.
- DER forecasts: Forecasted DER growth based on various scenarios, proposed by utilities and approved by regulators, that include details on expected siting at the distribution substation level and the potential impacts on distribution and transmission planning.
By proactively identifying optimal locations for use of DER, DRP guides smart grid modernization investments, expands customer choice, and secures value for all energy consumers.
To achieve these important goals, DRP establishes a comprehensive and transparent framework designed to improve distribution system planning, operations, and investment. The primary desired outcomes of DRP are to:
- Improve the safety, security, reliability, and resilience of the electricity grid, at fair and reasonable costs.
- Optimize use of existing electricity grid assets and new DER resources to modernize the grid while minimizing total system costs for ratepayers.
- Increase transparency of utility investments.
- Ensure that utility investments create a flexible, resilient grid and will meet customers’ future needs.
- Evaluate cost-effective DER alternatives to proposed investments in traditional infrastructure.
- Enhance the inputs utilized in utility Integrated Resources Plans.
- Guide cost-effective achievement of existing state renewable energy goals.
The Clean Coalition seeks to accelerate and support the implementation of effective DRP policies in states across the country. We support on-the-ground partners with policy expertise, model legislation, and coalition-building support.

The Clean Coalition first drafted DRP legislative language in California in 2011. Once this language was adopted in Assembly Bill 327 in 2013, the Clean Coalition guided the California Public Utilities Commission implementation of DRP and remains a regular intervenor in the DRP proceeding.
