SECI Bulk Renewable Energy EOI 2026: What C&I Buyers Should Know

SECI's July 2026 Expression of Interest gives large commercial and industrial power consumers a new route to aggregate long-term renewable electricity demand and develop solar, wind, hybrid, firm renewable or storage-backed projects. The published minimum requirement is 50 MW at one site or aggregated across multiple sites of the same consumer or group entity. SECI may consider smaller requirements where several consumers can be pooled into a commercially viable project.

This is not a power tariff award or a binding PPA. It is a demand-assessment exercise that SECI can use to structure projects and contracts after it understands buyers' load, locations, preferred technology, procurement model and credit profile.

Key takeaways

• Issuer: Solar Energy Corporation of India Limited (SECI), a Navratna public-sector enterprise under MNRE.
• Target buyers: C&I consumers, government bodies, distribution licensees, PSUs, institutions and other bulk electricity consumers.
• Minimum requirement: 50 MW at one location or across multiple locations of the same consumer or group; lower demand may be considered through aggregation.
• Possible technologies: solar, wind, solar-wind hybrid, firm and dispatchable renewable energy (FDRE), round-the-clock renewable power, BESS and pumped storage.
• Possible structures: third-party open access, captive, group captive, joint venture, REIA-led procurement, PMC and other mutually agreed models.
• Contract direction: long-term arrangements, with the EOI indicating preferences such as 15 or 25 years depending on technology and buyer need.
• Indicative delivery: industry reporting on the EOI says supply is expected about 12–24 months after a final PPA, subject to land and transmission readiness.
• Important caveat: responding to the EOI does not itself lock a tariff, approve open access or create a power-supply contract.

What has SECI invited C&I buyers to do?

SECI is asking prospective bulk buyers to describe their existing and future renewable power requirements. It wants enough information to aggregate demand across sectors, sites and states, then plan projects large enough to benefit from economies of scale.

The official EOI says SECI may support an end-to-end development pathway, including:

1. identifying or arranging suitable land;
2. facilitating state or interstate transmission connectivity;
3. developing solar, wind, hybrid, FDRE, RTC or storage-integrated projects;
4. managing EPC procurement and implementation;
5. structuring long-term PPAs or other contracts;
6. coordinating regulatory and open-access approvals; and
7. overseeing operation and maintenance.

For a multi-site manufacturer, that is potentially valuable because land, connectivity, approvals, tendering and project governance often require more management effort than comparing headline tariffs.

Who can participate in the SECI EOI?

The EOI is aimed at organisations with substantial electricity demand, including:

• manufacturing companies and industrial groups;
• data centres and other high-load commercial facilities;
• government departments and public-sector undertakings;
• distribution and deemed distribution licensees;
• institutions, ports, airports and metro systems; and
• other eligible bulk electricity consumers.

The stated minimum is 50 MW, either at one location or aggregated across multiple locations or sites of the same consumer or group entity. SECI also leaves room to consider lower requirements by aggregating more than one consumer.

That distinction matters. A single factory requiring 2–10 MW is not automatically eligible as a standalone 50 MW buyer. Its practical route would be aggregation with affiliated sites or other eligible consumers, subject to the structure SECI ultimately offers.

Which procurement models may be available?

The right model is not determined by the lowest quoted generation price alone. A C&I buyer should compare the landed cost of power after transmission, wheeling, cross-subsidy surcharge, additional surcharge, losses, banking and scheduling costs, as applicable to the chosen state and route.

Sun Wave's guides to open-access solar in India, group-captive solar and CAPEX vs OPEX vs open access explain those trade-offs in more detail.

What technologies can SECI aggregate?

The EOI is broader than a conventional solar PPA. It contemplates:

• standalone solar;
• standalone wind;
• solar-wind hybrid projects;
• FDRE and RTC configurations;
• battery energy storage systems;
• pumped-storage projects; and
• other renewable solutions suited to the buyer's operating profile.

A daytime factory with a stable six-day load may need a different portfolio from a 24/7 data centre or continuous-process plant. Buyers should provide interval load data rather than choosing a technology from an annual consumption total.

Does demand aggregation guarantee a lower electricity tariff?

No. Aggregation can improve scale, procurement competition and transmission utilisation, but the EOI does not guarantee a tariff or savings level.

The final commercial outcome will depend on:

• resource quality and project location;
• solar, wind and storage configuration;
• state or interstate connectivity;
• buyer credit and payment security;
• contract length and termination terms;
• open-access charges and losses;
• curtailment, scheduling and deviation risk;
• ALMM and other equipment requirements; and
• the allocation of change-in-law risk.

A credible comparison should use the buyer's landed renewable cost, not only the PPA energy charge. It should also model what happens when state charges, banking rules or demand patterns change.

What should a North India industrial buyer prepare?

Before responding or entering a later procurement stage, prepare a decision pack covering the following.

1. Load and site data

Provide at least 12 months of bills and, preferably, 15-minute or 30-minute interval data for each site. Separate base load, daytime load, seasonal peaks and planned expansion.

2. Procurement quantum

Estimate the MW and annual MWh required, but test the number against demand, sanctioned load, connectivity and renewable-consumption targets. Do not size solely from annual bill value.

3. Site and state map

List every consumption point, DISCOM, voltage level and state. A Faridabad factory, a Gurugram warehouse and a Rajasthan plant can face different open-access economics even under one corporate procurement strategy.

4. Preferred model

Decide whether the organisation can hold equity, accept a long-term PPA, provide payment security or own an asset. These constraints narrow the viable choice among third-party, captive, group-captive, JV and CAPEX structures.

5. Credit and approvals

SECI and project lenders will evaluate the buyer's credit quality. Internally, align finance, legal, sustainability, procurement and plant operations before entering a 15–25-year arrangement.

6. Risk limits

Document acceptable exposure to curtailment, market price, under-generation, grid outages, regulatory charges, delayed commissioning and termination liability.

How does this compare with rooftop solar?

SECI's EOI is primarily relevant to bulk, long-term off-site procurement. Rooftop solar remains the more direct option when a facility has usable roof area and strong daytime self-consumption.

For many industrial groups, the answer is a portfolio: rooftop solar for immediate behind-the-meter savings, plus open-access or group-captive power for demand that the roof cannot serve.

What happens next?

The EOI is a market-sounding and demand-aggregation step. SECI can use responses to decide project size, technology, location, implementation model and contractual structure. A later tender, developer selection or bilateral negotiation would establish the binding commercial terms.

Buyers should verify the live deadline, corrigenda and submission forms on SECI's official tender portal before acting. The reported response deadline for the July EOI is 17 August 2026, but official SECI notices and corrigenda should be treated as controlling.

Frequently Asked Questions

What is SECI's bulk renewable energy EOI?

It is a non-binding exercise to identify long-term renewable power demand from C&I and other bulk consumers. SECI may aggregate that demand and structure solar, wind, hybrid, FDRE, RTC or storage-backed projects under open-access, captive, group-captive, JV or other models.

What is the minimum capacity for the SECI EOI?

The official document states 50 MW at one location or aggregated across multiple locations or sites of the same consumer or group entity. SECI may consider smaller requirements where several consumers can be aggregated.

Can a factory needing less than 50 MW participate?

Potentially, but not necessarily as a standalone project. The EOI allows lower requirements to be considered through aggregation. Eligibility and grouping mechanics will depend on SECI's subsequent structure and final documents.

Does participation guarantee a renewable power tariff?

No. The EOI does not award a tariff or create a PPA. Binding prices, security, risk allocation and supply obligations would be set in later project and contract stages.

Which technologies can SECI develop for buyers?

The EOI includes solar, wind, hybrid, FDRE, RTC renewable power, battery energy storage, pumped storage and other suitable renewable solutions.

Is this better than rooftop solar for a factory?

It serves a different need. Rooftop solar is often the simplest route for daytime behind-the-meter savings. Aggregated off-site procurement is more relevant when a buyer needs much more energy than its roof can produce, has multiple sites or wants wind and storage in the supply mix.
