From fixed to flexible: Evolving models for sale of power by renewable power IPPs
Thematic Report
30 Sep 2025
The energy transition goals set by the Government of
India (GoI) are driving the country towards a renewable future. India’s
renewable energy (RE) capacity is projected to witness significant growth over
the current decade, with the combined share of renewable and hydro generation
in the all-India electricity generation expected to exceed 35% by 2030. This
transition is accompanied by evolving models for power sale in the RE sector.
Short-term electricity trading is gaining momentum, with
growing volumes in Real-Time Market (RTM) and Term-Ahead Market (TAM) segments.
Although spot tariffs moderated in FY2026, they remain high during peak hours,
especially during evening hours. Leading power producers are increasingly
targeting merchant market expansion to capitalise on these dynamics.
