Mandaluyong city: Measures are being undertaken to ensure transmission lines nationwide can accommodate the growing share of renewable energy (RE), an official of the National Transmission Corp. (TransCo) said Wednesday. RE now accounts for about 25 percent of the energy mix, in line with the government's target of 35 percent by 2030 and 50 percent by 2040.

According to Philippines News Agency, in an interview on the sidelines of Energyear Philippines 2026 in Mandaluyong City, TransCo President and Chief Executive Officer Fortunato Leynes said transmission bottlenecks persist due to delays in project implementation, mainly from right-of-way issues and capital expenditure approvals. He said these challenges and corresponding solutions will be identified under the Smart and Green Grid Plan, which forms part of the Philippine Energy Transition Strategies under the Philippine Energy Plan 2023-2050.

Leynes stated that the plan would determine the facilities needed to support new RE projects and is expected to be finalized "before the middle of the year." Earlier, officials of the National Grid Corp. of the Philippines (NGCP) cited the need to assess transmission capacity amid the rising share of RE.

While the NGCP mentioned it has contingency plans to address capacity fluctuations, it noted that proper measures must be in place to ensure an uninterrupted power supply.
