MERC Approves AEML-D 750 MW RTC Renewable Procurement
AEML-D said it filed the petition to meet rising electricity demand and fulfil Renewable Purchase Obligation requirements. The utility projected peak demand to grow from 2,056 MW in FY25 to around 2,739 MW by FY30 owing to commercial load growth, data centre expansion, transport electrification and higher residential use. It said fresh long-term procurement would be needed from FY28 to ensure reliability.
The auction on 22 April 2025 drew four participants offering a combined 1,500 MW. PTSL emerged as the lowest bidder at Rs 6.38/kWh, marginally below JSW Neo Energy at Rs 6.39/kWh, while MB Power and Goldi Solar quoted Rs 6.40/kWh and Rs 6.56/kWh respectively. PTSL plans to supply the contracted RTC power via a mix of 775 MW of solar, 300 MW of wind and 540 MW of thermal capacity for balancing.
The supplier will assume risks linked to renewable variability and interstate transmission charges and losses under the proposed arrangement. MERC noted the process complied with Ministry of Power guidelines and deemed the discovered tariff reflective. The commission compared the result with MSEDCL's 2,500 MW RE-RTC tender and found that after transmission costs the effective tariff there was around Rs 6.46/kWh at the Maharashtra periphery.
MERC also addressed concerns over availability of non-renewable balancing power and recorded that PTSL would arrange balancing from Vidarbha Industries Power Limited's Butibori thermal plant or alternate sources such as Mahan Energen Ltd under the draft power purchase agreement (PPA). The commission concluded the tariff was reasonable and in consumers' interest and directed AEML-D to file the executed agreement with PTSL. The order marks a step in Maharashtra's move towards firm renewable procurement as utilities seek clean power to meet rising demand and comply with renewable obligations.
