					</table><p>Renewable energy implementing agencies are leaning towards integrating energy storage systems with renewable energy to address the intermittency of solar and wind energy generation. The project configurations include round-the-clock power, firm and dispatchable energy, and assured peak power supply.</p>
<p>The bidding agencies are increasingly moving away from issuing standalone solar tenders. In 2025, only two standalone solar projects were auctioned.</p>
<p>Also in 2025, 11 renewables-plus-storage projects with a total capacity of 9.85 GW were auctioned. Of this, solar-plus-storage project auctions garnered the lowest tariffs.</p>
<p>Bidding agencies are increasingly moving away from issuing standalone solar tenders. In 2025, only two standalone solar projects were auctioned.</p>
<p>The lowest tariff recorded in these auctions in 2025 was ₹2.7 (~$0.0306)/kWh, a 20.8% drop from the ₹3.41 (~$0.037)/kWh recorded in 2024.</p>
<p>Here is a list of the five lowest solar-plus-storage tariffs discovered in auctions during 2025:</p>
<p><strong>#1 </strong>Ceigall India <a href="https://www.mercomindia.com/acme-and-ceigall-win-rumsls-600-mw-solar-plus-storage-auction" target="_blank" rel="noopener">won</a> 220 MW by quoting a tariff of ₹2.7 (~$0.0306)/kWh in Rewa Ultra Mega Solar’s auction to develop a 600 MW solar project with battery energy storage systems (BESS) in the Morena Solar Park, Madhya Pradesh. ACME Solar Holdings also secured 220 MW but at a slightly higher tariff of ₹2.765 (~$0.0313).</p>
