Conventional Generation · 01
Thermal Power
Coal-based power generation and thermal infrastructure.
Thermal plants turn fuel into heat, steam and rotation. A modern station adds fuel handling, water treatment, cooling, emission control and electrical infrastructure around its boiler, turbine and generator.
BARREL supports development and execution planning for supercritical and ultra-supercritical plants, modernisation, balance-of-plant packages and the associated electrical infrastructure.

Reactor design, nuclear fuel, safety-critical systems and licensed operation remain with competent, authorised organisations. In India nuclear activities fall under the national legal framework and the competent authorities, including AERB. BARREL does not represent itself as a reactor designer, fuel supplier, operator or licensed facility, and every package follows its nuclear safety classification.
Our responsibility statement
Nuclear and large thermal projects need specialist qualifications, statutory permissions and safety regimes. BARREL distinguishes its coordination and project-support role from work that must be performed by authorised owners, designers, contractors and operators. Every proposal states which scope BARREL delivers directly, which it coordinates, and which a qualified partner executes.
