Solar with Battery Storage System to Lower Peak-Hour Charges (ToD) for Seven Seas Incorporate, Pune

Seven Seas, a plastic injection moulding industry based in Pune, was navigating a regulatory shift reshaping electricity cost across Maharashtra: the introduction of Time-of-Day (ToD) tariffs, under which electricity costs more during certain hours of the day. For businesses running significant loads during those peak-tariff windows, this policy change meant rising costs that had little to do with how much power they used, and everything to do with when they used it.

To get ahead of this, Seven Seas turned to Orb Energy for a solar with battery storage solution. Rather than relying on solar power only as it was generated, a BESS (Battery Energy Storage System) was added to store excess solar energy produced during the day and release it during high-tariff hours — shifting consumption away from the grid at exactly the moments electricity cost the most.

The impact showed up quickly in the numbers: a 55% reduction in peak-hour grid consumption and a 35% reduction in monthly electricity costs. For Seven Seas, that meant lower bills and far less exposure to the grid during the hours that mattered most.

The broader lesson applies well beyond one business: with ToD tariffs now in effect across Maharashtra, managing when electricity is consumed is becoming just as important as managing how much. Solar + battery storage, backed by BESS, gives businesses that control — turning stored daytime solar into real savings and greater energy independence.
