Oylat Hydroelectric Power Plant

Audit Analysis

The Oylat Hydroelectric Power Plant is a grid-connected renewable energy project under VCS with a VVB-confirmed investment additionality test and a jurisdictional baseline. The project delivered 72.6% of its pro-rata ex-ante expectation for the monitored period, reflecting conservative (under-)delivery driven by lower precipitation. Several contradictions between the 2014 validation report and the 2023 verification report were resolved in favour of the more recent verification report, and all 23 corrective action requests raised during verification were resolved.

Project Description

Red Flags

• ⚠The PDD estimated 42,817 tCO2e over the full crediting period, but the verification report confirms only 18,653 tCO2e for the 6-year monitoring period (72.6% of the pro-rata expectation of ~25,690 tCO2e), indicating the ex-ante estimate was optimistic due to precipitation sensitivity.
• ⚠The validation report (2014) describes the baseline as project-specific while the verification report (2023) describes it as jurisdictional; the more robust jurisdictional characterisation is privileged, but the discrepancy warrants attention.
• ⚠23 Corrective Action Requests and 2 Compliance Log entries were raised during verification, indicating non-trivial documentation or MRV issues that had to be remediated before issuance.
