Community Power Map

Where are communities taking charge of their energy future? Which states give communities the most power?

ILSR’s Community Power Map provides an interactive illustration of how communities are accelerating the transition toward 100% renewable energy and how policies help or hinder greater local action.

Inevitably, we missed some of the exciting local renewable energy projects happening around the nation. That’s where you come in. Fill out our form and we will be continually be updating our map.

How to Use the Map

The map provides markers to show local activity and layers to highlight state policies. The markers include:

  • Local Community Renewable Energy Projects, mostly community solar and community wind
  • Community Groups that are helping take charge of their community’s energy future
  • 100% Renewable commitments by cities, either for electricity for municipal use (small markers) or on behalf of the entire city (large markers).
  • Utility (Feed-in) Tariffs that allow small power producers a simplified path to selling energy from new, distributed renewable energy projects into the electric system.

The layers include:

  • The State Community Power (CP) Score, a value assigned each state based on its policies supporting local energy action.
  • Net Metering policies, including those that allow customers to aggregate their energy use across multiple buildings or generate energy off-site
  • Property Assessed Clean Energy (PACE) financing that allows communities to set up repayment programs for energy efficiency and renewable energy through the property tax system
  • Community Choice Aggregation laws allowing cities to choose their energy suppliers on behalf of all residential and small commercial customers
  • State (Feed-In) Tariffs that allow small power producers a simplified path to selling energy from new, distributed renewable energy projects into the electric system.
  • Residential Energy Building Codes that allow cities to set higher standards than the state, or give cities the ultimate authority
  • State Renewable Portfolio Standard Carve-Outs for solar or distributed renewable energy that require utility companies to purchase renewable electricity specifically from small-scale sources

State Community Power Score Methodology

The Community Power Score assigns points to each state based on its policy environment for supporting local energy action. It includes points for all of the state policies in the map above. The scoring is as follows:

Net Metering 5 points for a net metering policy, 6 for also having aggregate net metering, 8 for having virtual net metering
Property Assessed Clean Energy (PACE) 3 points for Residential or Commercial PACE, 5 points for both
Community Choice Aggregation 7 points for having a state CCA policy
State (Feed-in) Tariffs 3 points for having a state feed-in tariff
Residential Energy Building Codes 1 point for a state-set code, 3 points for local authority with no state code, 5 points for a state code with local stretch code
State Renewable Portfolio Standard Carve-Outs 5 points for a distributed generation or solar-specific renewable portfolio standard
