Mott MacDonald completes EIA for geothermal in Indonesia

Mott MacDonald has conducted three environmental and social impact assessments (ESIAs) for three geothermal power plant projects for Pertamina Geothermal Energy in Indonesia.

The ESIAs were undertaken to satisfy various World Bank safeguard policies to facilitate potential future World Bank funding of the geothermal projects.

The projects are:

  • A 220 MW geothermal plant in Lumat Balai;
  • A 40 MW geothermal plant in Lahendong; and
  • A 110 MW geothermal plant in Ulubelu.

Following initial phases of development, the three geothermal sites are at various stages of drilling for production and reinjection wells. The next phase will include the development of an above ground steam system, power plant and electrical connection.
