3.2 Mae Moh Solar Farm Project, Phase 1, Lampang Province
This project involves a ground-mounted solar farm with a net generating capacity of 38.5 MW, developed to replace electricity supplied from the transmission system of Mae Moh Mine used in mining activities. It also aims to increase EGAT’s share of renewable energy generation and support its Carbon Neutrality policy. The electricity generated is not intended for commercial sales. The first generating system was tested and synchronized with the Mae Moh Mine power system on December 12, 2025, and full-capacity operation was expected within the first quarter of 2026.
