Pumped Storage Hydropower Projects

adjustable speed pump-turbine is proposedfor supporting the renewable energy (solar and wind)

• Electricity from Hydropower is served for peak load.

• The operation of hydropower make for minimum release

water as per the monthly/weekly water requirement plan.

• Urbanization in the downstream area (Water requirement for

Water supply, Environmental Flow and Flood Mitigation are

important)

• The operation of hydropower is limited for the riparian house,

tourism and fishery. However, EGAT uses the telemetering

system for monitoring during operation.

Emerging Constraints on Operational Coordination of HP Projects in Thailand

8

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.
