Grid-forming battery energy storage for renewable developers, IPPs, and industry — shift midday solar into the evening peak, stabilise weak grids, and meet India’s new grid-forming connectivity norms. Co-located with your plant or standalone, under CAPEX or OPEX.
Solar generates from 6 am to 6 pm nearly year-round, and monsoon wind surges May to September — but the evening peak arrives just as solar disappears, and the old thermal fleet cannot ramp down to make room at midday.
Midday solar gets curtailed because inflexible thermal plants can’t back down — then the 7–11 pm peak has to be met with expensive power. Every curtailed unit is lost revenue for a developer; every evening unit bought is an expensive one for a discom.
BESS shifts the surplus into the hours it’s worth the most
Desert RE zones in Rajasthan and Gujarat sit at the end of long lines with low short-circuit strength. Conventional grid-following inverters lose stability at these nodes — the 2026 Khavda disturbance made this a national priority.
Grid-forming inverters are built for exactly these conditions
Grid-forming (GFM) inverters behave like virtual synchronous generators — they establish their own voltage and frequency reference instead of following the grid’s, actively supporting the system the way retiring thermal machines once did.
Near-instantaneous response to frequency deviations, replacing the rotating inertia the grid loses as thermal plants retire.
Independent V/f reference with disturbance ride-through — the system stays stable even when the surrounding grid is weak.
Re-energise sections of the network after an outage — a capability now required of large BESS installations by the grid code.
Stable operation at very low short-circuit ratios, unlocking feed-in capacity at constrained nodes where grid-following plants are limited.
In 2026, grid-forming storage moved from premium feature to connection requirement — and the incentive stack makes projects bankable.
CEA’s 2026 advisory calls for 100% grid-forming inverters on upcoming BESS projects, black-start capability for systems of 50 MW and above, and GFM on a share of new renewable plant capacity. Buying grid-following storage today risks buying a stranded asset.
Our systems are specified GFM-first, compliance-ready
The Ministry of Power advises minimum two-hour co-located storage with new solar tenders, states are writing their own co-location rules, and the Energy Storage Obligation requires discoms to procure storage year after year.
Co-located BESS keeps your project tender-eligible
The current VGF tranche supports standalone BESS with up to ₹18 lakh per MWh, and a further outlay was approved in 2026 to back roughly 30 GWh of new capacity. Figures are indicative and subject to prevailing scheme rules.
We map your project to the right scheme and tender
Co-located battery projects commissioned by June 2028 enjoy a long-term waiver of inter-state transmission charges — a material improvement to project returns for hybrid and FDRE configurations.
Timelines matter — early movers capture the waiver
SCR assessment, evacuation feasibility, curtailment and tariff analysis at your node.
MW / MWh sizing, cycling strategy, and mapping to VGF, tenders, and the right structure.
GFM inverter selection, LFP battery blocks, protection design, and compliance simulation studies.
Civil works, DC blocks, PCS, transformers, grid connection, and commissioning tests.
State-of-health monitoring, warranty management, and planned capacity augmentation over life.
Share your connectivity details and load or tender profile — we’ll return sizing, a revenue stack, and the ownership structure that makes it bankable.
