2023 Study by Claire Dépit-Strömbäck (LEAN Energy US)
Community Choice Aggregation: A Cost-Effective Policy Tool that Accelerates Competitive Renewable Power Addition and Carbon Reduction at Scale
​After many months of research, surveys, focus groups, and industry leader interviews, LEAN's study shows the CCA model as an efficient, equitable and cost-effective policy tool for providing competitive pricing and renewable power to a large number of electricity consumers in the United States. The study reviews state-by-state market status, national impacts, and most importantly, an analysis covering the potential of CCAs to accelerate state and national governments' environmental, social and economic goals in the energy sector.
