Clean Development Mechanism (CDM) Project for Kamojang Unit-4 Geothermal Power Plant

Abstract

The Geothermal Power Plant Kamojang Unit-4 is owned by PT. Pertamina Geothermal Energy (PGE) which started operation commercial on January 26, 2008. The power plant has an installed capacity of 63 MW and generates an estimated power generation of 473 GWh per annum. The electricity from the power plant is then transmitted to the National Power Grid. The CDM project of the power plant is developed by PGE in collaboration with PT. Perusahaan Listrik Negara (PLN).

Methodologies for baseline and monitoring plan of CDM project used ACM0002 Consolidated baseline methodology for grid connected electricity generation from renewable sources” version 07. Validation visit for Kamojang Geothermal Project Design Document (PDD) assessment according to the specific requirement of the methodology was conducted on March 10-11, 2008. Common approach on recent trend in CDM development would require more information on financial and industrial situation in the host country, which is critical for additionality argument.

The final PDD is expected to be registered at UNFCCC Executive Board on October 2009. The next milestones on CDM project cycle would be CDM project Implementation & monitoring activities, and subsequently periodic verification and issuance of Certified Emission Reduction (CER). Certified Emission Reduction (CER) sales can make geothermal projects in Indonesia economically viable based on 403,727 tones of CO2e per year emission reduction. This calculation is using emission factor of 0,891 Ton C02e / MWh in JAMALI Interconnected grid.
