GK Energy plans 15-year fixed revenue from BESS assets

GK Energy Limited plans to own utility-scale battery energy storage system, or BESS, plants that take power from distribution companies, or DISCOMs, and sell it back under a fixed-revenue model for 15 years from installation, according to management. The proposed model moves beyond engineering, procurement and construction, or EPC, work, with broad capital expenditure estimated at Rs 90 lakh to Rs 1 crore per megawatt-hour, or MWh.

How will GK Energy’s BESS business model work?

GK Energy plans to install and own utility-scale BESS plants rather than only execute EPC projects for storage customers. Management said the company would get power from DISCOMs and sell power back to DISCOMs, describing the arrangement as a capital-expenditure, or capex, model. Under this mechanism, GK Energy would retain the storage asset after installation instead of completing a one-time construction assignment.

The BESS model is intended to manage the timing difference between solar generation and electricity demand during non-solar hours. Management said India has daytime power-supply security, but excess power generated in the day needs storage for later use. It said hundreds of MWh of energy were lost in the current year because storage was unavailable, while further gigawatts of solar installation capacity are coming.

Management described the new activity as adjacent to GK Energy’s existing solar work rather than as an unrelated diversification. The company has solar-pump and rooftop operations, and management said BESS can provide leverage as solar capacity expands. It did not disclose a BESS project capacity, location, commissioning date or a named DISCOM counterparty during the call.

What does the 15-year BESS revenue model mean for GK Energy?

GK Energy said its intended BESS structure would have fixed revenue for 15 years from the date of installation. Management presented that duration as the basis for building stable income sources alongside its existing operations. The call did not disclose a signed 15-year contract, fixed tariff, annual revenue amount or minimum utilisation requirement for any individual storage asset.

The planned structure differs from an EPC-only role because GK Energy expects to invest in, own and operate the BESS plant. Management said it preferred what it called a secure business mechanism over taking risks it considered unnecessary. Its comments on constant growth and an assured bottom line were management expectations, not reported earnings or a financial forecast from an operating BESS project.

A 15-year revenue period would make the timing and terms of the DISCOM arrangements central to the model. However, GK Energy did not provide details on the contractual payment mechanism, performance guarantees, tariff escalation, grid-charging cost or penalties. The disclosed commercial framework is therefore a proposed operating model, rather than a quantified addition to revenue or profit.

What will GK Energy’s BESS assets cost and how long can batteries operate?

GK Energy gave a broad capex indication of Rs 90 lakh to Rs 1 crore per MWh of BESS capacity. Management said the figure can vary by project, location and number of storage hours, making it an indicative unit-cost range rather than a budget for a specific plant. It did not disclose an expected BESS margin, total project outlay or operations-and-maintenance cost.

Management said current market products provide about 8,000 to 10,000 battery cycles. Lithium-ion is the technology currently available, while sodium-ion batteries are also in development, according to management. It suggested that future products could reach 12,000 to 15,000 cycles, but identified the 8,000-to-10,000-cycle range as the current market-product position.

The difference between the current 8,000-to-10,000-cycle range and the possible 12,000-to-15,000-cycle range is prospective rather than an announced GK Energy deployment plan. Management did not specify which battery chemistry it would select for its own plants. It also did not state how many cycles a proposed 15-year asset would use annually or when battery replacement may be required.

How does BESS fit GK Energy’s funding and receivables position?

GK Energy said it had sufficient debt already taken and that profits generated by the business would help it pursue its targets. Management said it did not intend to dilute equity at the current stage or price band, although Gopal Kabra and Mehul together held about 79-point-some percent and would need to reduce that holding to 75% within two years. No separate BESS debt facility or project-financing plan was disclosed.

Existing-business receivables provide context, but not a forecast for BESS cash flows. Management said first-half receivables stood at 200 days, while Rs 375 crore collected in October reduced its calculation to 128 days. It expects year-end receivables of 120 to 150 days, but did not provide equivalent collection terms, working-capital requirements or DISCOM payment assumptions for storage assets.

The company said it would maintain its existing approach of not pursuing orders aggressively if collections were not as expected. That comment concerned order intake and receivables management in its operating business, not a defined BESS investment hurdle. Whether owned storage assets require additional borrowings will depend on project capacity, capex and contract terms that were not disclosed.

How does BESS complement GK Energy’s solar and pump business?

GK Energy linked BESS to its growing solar activity, including module and cell procurement. Management said it had confirmative agreements for 875 megawatts of module and cell supply in the current year, compared with purchases of about 300 megawatts from two cell manufacturers in the previous year. This increase concerns solar equipment procurement, not committed BESS capacity, but management cited expanding solar installations as the reason storage is needed.

Management said GK Energy could grow close to 40% in the current year even without the PM KUSUM programme. It also said the company would be on track for Rs 3,000 crore of revenue if PM KUSUM rolls out well and on time. Those revenue comments relate principally to the established solar-pump opportunity, as the company gave no BESS revenue target for the current year or the next financial year.

Management expects PM KUSUM developments in the third quarter and said the company would receive the scheme’s benefits from the fourth quarter onward. It said technical discussions were under way on potential product upgrades to the programme, which has been discussed for more than five years. BESS remains a separate proposed utility-scale ownership model, with no disclosed link between PM KUSUM funding and storage-asset capex.

Conclusion

GK Energy’s stated BESS plan would add an asset-owning model to its EPC and solar-related activities, using DISCOM charging and supply arrangements to seek fixed revenue for 15 years after installation. The disclosed economics remain limited to broad capex of Rs 90 lakh to Rs 1 crore per MWh and current battery capability of 8,000 to 10,000 cycles, so the effect on revenue, margins and debt cannot yet be calculated.

The next items to watch are whether GK Energy identifies BESS capacity, DISCOM contracts, tariffs, financing and commissioning dates for the proposed plants. Management also expects PM KUSUM-related developments in the third quarter, with benefits from the fourth quarter onward, and has guided to 120 to 150 year-end receivable days after the Rs 375 crore October collection.
