However, EGAT uses the telemetering system for monitoring during operation. 8 8 Emerging Constraints on Operational Coordination of HP Projects in Thailand The constraint for Hydropower Development • The potential sites are limited due to the topography condition. The potential sites are mainly located in Watershed Class 1A where are the forest cover that has never faced the disturbance of any kind. The environmental impact is very concerned. • NGO/ Some Civil Society not accept for the large hydropower development. 9 9.
