Juniper Green targets 10,000 MWh of storage by March 2028

Juniper Green Energy targets about 10,000 megawatt-hours (MWh) of battery energy storage system (BESS) installations by March 2028. Juniper Green had commissioned about 503 MWh in H1 FY27 and reported 604 MWh of operational BESS as on date, while setting an interim installation target of about 4,500 MWh by June 2027.

What is Juniper Green's battery storage target?

Juniper Green targets about 4,500 MWh of BESS installation by June 2027 and about 10,000 MWh by March 2028. The company presents these as installation targets, distinct from the 604 MWh operational BESS capacity reported as on date in its H1 FY27 business update.

The March 2028 target is 9,396 MWh above the operational base of 604 MWh. Reaching the June 2027 milestone from that base would require 3,896 MWh of further installations, followed by 5,500 MWh to move from the June 2027 target to 10,000 MWh by March 2028.

Juniper Green reported a total portfolio of 11,218 megawatt-peak (MWp) of renewable capacity and 8,989 MWh of BESS as on date. The 10,000 MWh installation target is 1,011 MWh above that reported BESS portfolio figure, showing that the stated March 2028 plan extends beyond the portfolio capacity disclosed at the time.

How much BESS has Juniper Green commissioned in FY27?

Juniper Green commissioned about 503 MWh of BESS in H1 FY27, increasing operational BESS capacity from 101 MWh in FY26 to 604 MWh as on date. The reported addition accounts for most of the operational base, with the remaining 101 MWh representing the FY26 capacity.

The company also commissioned 917 MWp of renewable capacity in H1 FY27, comprising 494 MWp of solar and 423 MW of wind. After September 30, 2026, Juniper Green commissioned a further 119 MW of wind, taking its operational renewable capacity to 2,844 MWp as on date.

Its FY27 capacity-additions table reports BESS commissioning at three special purpose vehicles, or SPVs: 201 MWh at Juniper Green Stellar Pvt. Ltd., 201 MWh at Juniper Green Stellar Pvt. Ltd. - GS, and 100 MWh at Juniper Green Cosmic Pvt. Ltd. The table reports a FY27 total of 503 MWh, alongside 1,036 MWp of renewable capacity additions across 11 sites in three states.

What supports Juniper Green's storage expansion plan?

Juniper Green cites in-house engineering, procurement and construction capability, connectivity and land availability as execution inputs for its plan. It says its in-house team enables parallel execution across multiple sites and states at state transmission utility and central transmission utility levels, after commissioning 1,036 MWp and 503 MWh in FY27 till date.

The company says connectivity, including capacity granted and/or applied for, is available for its full portfolio. It also reports more than 5,200 MW of surplus connectivity for future bids and connectivity for installation of more than 20,000 MWh of BESS, with both measures including granted and/or applied-for capacity.

Juniper Green further reports more than 16,000 acres of land available for under-construction, contracted and awarded projects. It has also identified more than 100 locations for wind-turbine installation in those categories, although the presentation does not allocate a specific share of the land or connectivity to BESS projects.

Which projects include Juniper Green battery storage?

Juniper Green's disclosed 230 MW Solar Energy Corporation of India, or SECI, firm and dispatchable renewable energy round-the-clock thermal-mimic project is planned with 870 MWp of renewable capacity and 2,200 MWh of BESS. The company received a letter of award for the contracted 230 MW capacity at a tariff of Rs 5.26 per kilowatt-hour.

The 2,200 MWh storage plan for the SECI project equals more than three times Juniper Green's 604 MWh operational BESS capacity as on date. It is also one identified component of the company’s 8,989 MWh BESS portfolio, rather than evidence that the entire portfolio is operational.

Separately, Juniper Green signed a 50 MW power purchase agreement with SJVN under its firm and dispatchable renewable energy portfolio at Rs 4.25 per kilowatt-hour. It also received a letter of award from GUVNL for a 50 MW wind project at Rs 3.51 per kilowatt-hour, while reporting the commissioning of India’s first project under the SJVN FDRE scheme tender.

How did Juniper Green's H1 FY27 operations perform?

Juniper Green generated 2,075 million units in H1 FY27, up 98% from 1,046 million units in H1 FY26. The company attributed the increase to capacity additions and wind performance, as its total capacity utilisation factor, or CUF, rose to 28.5% from 24.1%.

Wind CUF increased to 50.0% in H1 FY27 from 41.3% a year earlier. Juniper Green Beam, a 50.4 MW wind project, recorded a 58.3% CUF, while the 72.45 MW Juniper Green Kite project recorded 57.9% during the half year.

Plant availability was 98.7% in H1 FY27, compared with 99.1% in H1 FY26, while grid availability rose to 99.5% from 99.4%. Juniper Green calculates CUF on alternating-current capacity from the month after full project commissioning and excludes the impact of power curtailment when calculating grid availability.

Conclusion

Juniper Green has set out a storage expansion path from 604 MWh of operational BESS as on date to about 4,500 MWh by June 2027 and about 10,000 MWh by March 2028. Its H1 FY27 commissioning of about 503 MWh, combined with a disclosed 2,200 MWh BESS plan for the SECI project, shows that storage is being incorporated into both operating additions and contracted renewable projects.

The next disclosed milestone is the June 2027 target of about 4,500 MWh of BESS installations, followed by the March 2028 objective of about 10,000 MWh. Progress will depend on the pace of commissioning, including projects supported by connectivity that Juniper Green describes as granted and/or applied for, and on conversion of its 8,989 MWh BESS portfolio into installed capacity.
