RWE Renewables Korea has proposed a comprehensive strategy to address grid congestion by bundling three key solutions: oversubscription, flexible grid connection, and energy storage systems (ESS). According to the company, this integrated approach can expand renewable energy capacity by 50-80% at existing connection points without requiring new transmission line construction.
The proposal aims to support South Korea's ambitious 2030 renewable energy target of 100GW capacity by improving grid utilization rates rather than expanding physical infrastructure. By optimizing the use of existing grid connection points, the strategy offers a cost-effective solution to accommodate the rapid growth of renewable energy sources while addressing current bottlenecks in the power system.
RWE Renewables Korea has identified repowering of aging wind and solar farms as the priority application for this bundled approach. By upgrading existing renewable energy facilities with modern technology while implementing flexible connection and storage solutions, the company believes the strategy can maximize energy output from current infrastructure investments.
The proposal emphasizes the importance of increasing power generation capacity per connection point as a foundational step. This approach would allow the grid to breathe more easily while meeting Korea's renewable energy expansion goals, offering a practical pathway to decarbonization without the delays and costs associated with major grid infrastructure upgrades.
