en.Wedoany.com Reported - Rewa Ultra Mega Solar Limited (RUMSL) has launched two solar-plus-storage projects with a total contracted capacity of 250 MW, with the International Finance Corporation (IFC) serving as transaction advisor. The two projects, sized at 50 MW and 200 MW respectively, are designed to provide an equivalent level of power supply during both peak hours and solar hours, in order to optimize transmission capacity utilization.
Manu Srivastava, Additional Chief Secretary of Madhya Pradesh, disclosed on social media that the projects are committed to providing four hours and six hours of guaranteed power during peak periods, respectively, while also supplying daytime solar power to the state. Interested bidders can register and download the Request for Proposal (RFP) and related documents through the RUMSL tender portal. The pre-bid meetings for both projects are scheduled for May 29, 2026, at 11:30 AM at MP Bhawan, Chanakyapuri, New Delhi.
RUMSL stated that these two projects provide smooth power supply during both peak and solar hours, paving the way for the company's planned 24-hour uniform power supply projects. Madhya Pradesh has previously achieved some of India's lowest tariffs for solar-plus-storage, awarding contracts at ₹2.70/kWh to CEIGALL India Limited and ₹2.76/kWh to ACME Group. The project includes 600 MW of solar capacity and 220 MW/880 MWh of Battery Energy Storage System (BESS), featuring free night-time charging (10 PM to 5 AM), low charging power demand incentives, a solar export cap with tariff reduction for excess generation, a three-tier payment security mechanism, 100% land allocation, and internal and external evacuation infrastructure provided by the state government.
According to state government officials, this is the first time in India that a Firm and Dispatchable Renewable Energy (FDRE) project has achieved a tariff below ₹3/kWh. The previous tender was issued by Madhya Pradesh Power Management Company Limited (MPPMCL), laying the foundation for more economical and reliable renewable energy supply in the country.
Chief Secretary Anurag Jain (with an electrical engineering background) emphasized from the outset that these projects should be technology-neutral. Srivastava added that these are among India's first truly technology-neutral projects, allowing bidders to adopt battery storage, Pumped Storage Plants (PSP), or other storage technologies located anywhere in India. Battery storage is co-located with the solar project, whereas PSP can only be built at specific locations. To accommodate this, developers can site project components either inside or outside the solar park. Inside the park, RUMSL provides land and evacuation infrastructure to the State Transmission Utility (STU); outside the park, developers arrange land and evacuation infrastructure at their own cost (connecting to either the STU or the Central Transmission Utility, CTU). For projects connecting to the Inter-State Transmission System (ISTS), transmission charges and losses will be factored into the bid to allow for a fair comparison based on the landed tariff at the state grid boundary.
The project has received support from multiple institutions, including Trilegal, PwC, Deloitte, SgurrEnergy, the Sequoia Climate Foundation, the Shakti Sustainable Energy Foundation, the Centre for Energy Transition Mission (CMET), the India Energy and Climate Center (IECC) at UC Berkeley, and IDinsight. This initiative builds on the experience of Madhya Pradesh's previous Morena Solar-plus-Storage project, Rewa project, and ASN project, all of which achieved record low tariffs.
