Maharashtra sets mandatory storage rules for new renewable projects

The Energy Department's FAQ says projects with in-principle grid approval before March 18, 2026 will remain under the earlier 2015 or 2020 policy frameworks. New projects must commission the required battery capacity alongside each renewable phase, although storage may be shared at a common pooling substation when metering can verify project-level accounting. Projects seeking electricity-duty exemption face a higher minimum of 2 MWh per megawatt, making storage design a central part of project eligibility and economics.
