Why choose an Indian O&M partner
Cost base
Teams are recruited, certified and managed out of India, so an OEG contract carries an Indian cost base rather than a Western one, at the same contracted plant KPIs.
Depth
OEG runs one of India's larger third-party O&M fleets (34 thermal stations plus solar and DG assets), so gas-plant sites draw on a bench of certified engineers rather than single-site hires.
Track record
30+ years of continuous O&M contracting; listed Indian company with audited financials and credit ratings.
Mobilisation
OEG runs both Indian and international operations, with established experience deploying and running complete O&M teams outside India - 514 MW operated overseas as of March 2025.
Anonymised gas & overseas references
Most O&M contracts carry confidentiality clauses, so plants are listed by type rather than client name.
| Combined-cycle plant | 220 MW CCGT - full O&M, sustained 99% plant load factor |
|---|---|
| Fleet under O&M | 5,482 MW in India and 514 MW overseas as of March 2025, across 34 thermal stations plus solar and DG assets |
Named client references and site-visit contacts are available under NDA during pre-qualification.
