It highlights that local solar and wind resources, bolstered by IRA tax credits and the ability to reuse existing grid interconnections, offer a cost-effective path for coal retirement. The analysis suggests that the savings from this transition could fund 137 GW of four-hour battery storage to maintain grid reliability. The authors recommend that policymakers update resource plans, improve interconnection processes, and utilize IRA financing to ensure a just economic transition for coal-dependent communities.","ai_generated":true,"unit":"eninnova-000065#summary","date_modified":"2026-10-23"},"key_insights":[{"text":"Local renewable resources sited within 45 kilometers of coal plants are highly cost-competitive, with 97 percent of plants being more expensive to operate than these local options.
