Thermal plant O&M business faces long-term structural headwinds from energy transition

Concentrated customer base in power sector creates revenue dependency risk
Source: Company Financial Filings
O&M service revenues are concentrated in a small number of long-term contracts; loss or non-renewal of key contracts can cause substantial revenue decline.
India's power sector is heavily regulated; changes in electricity tariff orders, renewable energy mandates, or plant performance standards can impact O&M contract terms and revenues.
As India transitions from thermal to renewable energy, thermal plant O&M revenues face a long-term secular decline; companies must pivot to renewable O&M capabilities.
O&M services for government-owned power plants can involve delayed payments from state electricity boards, creating receivables risk and cash flow strain.
Specialized power plant O&M requires certified engineers and technical staff; talent retention is challenging given competition from large power companies and EPC firms.
