Gunung Rajabasa Geothermal Power Plant

Audit Analysis

The Gunung Rajabasa Geothermal Power Plant is a CDM-registered renewable energy project validated by TÜV NORD CERT with a confirmed investment additionality test, but the validation process surfaced 15 material findings and 12 corrective actions, including calculation errors in the investment analysis and grid emission factor. No monitoring reports or verified emission reduction figures are available in the extracted record, and the grid emission factor dates from 2007, raising over-crediting concerns. The project's low permanence risk (power generation, no carbon storage) and negligible leakage are appropriate for its type, but the absence of any post-validation monitoring data and low extraction confidence limit confidence in the overall credit quality.

Project Description

Red Flags

• ⚠Grid emission factor of 0.724 tCO2/MWh is from 2007 and the validation report flagged calculation errors (IPCC uncertainty levels, coal type, Build Margin comparison) — the baseline may overstate displacement benefits if Indonesia's grid has decarbonised since then.
• ⚠Four separate corrective actions (CAR B1, B2, B6, B10) targeted the investment additionality analysis, including IRR/cost calculation errors and an expired additionality tool version, indicating the additionality case required substantial remediation before VVB sign-off.
• ⚠No monitoring reports, verified ERR figures, or monitoring period data are present in the extracted record, making it impossible to confirm that the project is actually delivering the 7,739,675 tCO2e claimed over the 2016–2023 crediting period.
• ⚠The full Environmental Impact Assessment was not yet completed at validation (only an exploration-phase pre-assessment existed), and the validation report required a full EIA before exploitation.
