The most severe deficit of 37.9% by 2038 is projected under both synchronous and sequential phase-out scenarios. To mitigate these risks, the report argues for additional renewable capacity beyond current plans, improved transmission infrastructure, and the implementation of battery energy storage systems (BESS).","ai_generated":true,"unit":"transfor-000068#summary","date_modified":"2026-10-23"},"key_insights":[{"text":"Average energy balances are projected to remain positive across all analyzed scenarios through 2038, as new projects are expected to compensate for the energy lost from retired thermal plants.
