Eskom has taken a major step in unlocking much-needed grid capacity for wind projects in the Western and Eastern Cape provinces by publishing the highly-anticipated curtailment addendum to its latest Generation Connection Capacity Assessment, or GCCA 2025. The addendum, which has been published on Eskom’s website and has been approved by the National Energy Regulator of South Africa (Nersa), states that, by accepting a “reasonable share of no more than 10% of curtailment”, 3 470 MW of additional grid capacity to connect wind generation will be made available, including 2 680 MW in the Western Cape and 790 MW in the Eastern Cape.
