Plans to accelerate the closure of Australia's biggest coal-fired plant have the potential to create electricity shortages in three states unless enhancements to the grid proceed and new generation and storage capacity is added, the market operator said.

The shortfall assessment is contained in an updated electricity statement of opportunities (Esoo) report. It was prompted by Origin Energy's February decision to bring forward closure of its 2,880-megawatt Eraring plant in New South Wales by seven years, to 2025.

NSW (where possible shortfall has been advanced by four years) faced a reliability gap of 590MW capacity from 2025-26.

Victoria faced a gap of 330MW from 2028-29.

Queensland faced a gap of 770MW from 2029-30.
