What Is This Tender?

NHPC Renewable Energy Limited (NHPC REL) — the renewable energy subsidiary of NHPC Limited (National Hydroelectric Power Corporation) — issued a Request for Selection (RfS) in March 2026 for 30.93 MW of grid-connected rooftop solar projects on government buildings across 20 districts of Haryana.

The tender is being implemented under PM Surya Ghar Muft Bijli Yojana (PMSG-MBY) — the Government of India's flagship rooftop solar programme — on a RESCO (Renewable Energy Service Company) model. HAREDA (Haryana Renewable Energy Development Agency) is the nodal state facilitator, while NHPC REL acts as the central procuring agency.

This tender is particularly significant for the Delhi-NCR and Haryana region because:

• Faridabad — the home district of Sun Wave Technologies — is explicitly listed as one of the covered districts
• Gurugram — Haryana's largest industrial and commercial hub — is included
• The 20-district geographic sweep covers virtually all of Haryana's major industrial and urban centres

NHPC REL has emerged as a major player in rooftop solar RESCO procurement for government buildings alongside SECI, having simultaneously issued similar tenders for J&K (23.34 MW) and multiple other states in early 2026.

Districts Covered

The 30.93 MW tender covers government buildings across 20 Haryana districts:

Ambala, Faridabad, Karnal, Panchkula, Rewari, Rohtak, Gurugram, Hisar, Jhajjar, Jind, Kaithal, Kurukshetra, Mahendragarh, Palwal, Panipat, Sirsa, Yamunanagar, Sonipat, Fatehabad, and Bhiwadi.

This covers Haryana's full industrial belt — from Faridabad and Gurugram (Delhi-NCR industrial districts) through the central districts of Rohtak, Panipat, Karnal to the western districts of Hisar, Sirsa, and Fatehabad.

For industrial solar buyers in Haryana: The geographic spread of this tender reflects the density of government infrastructure across all of Haryana's districts. The RESCO model for government buildings creates a parallel track of solar adoption in the public sector — while private industrial buyers explore their own solar options independently.

Project Model and Scope

RESCO model: Selected developers will finance, build, own, and operate the rooftop solar systems on Haryana government buildings. The government departments pay only for the solar electricity generated at the bid-discovered tariff, with zero upfront capital investment.

Developer responsibilities:

• Full EPC of rooftop solar systems (design, supply, installation, testing, commissioning)
• Long-term O&M for the duration of the PPA
• Performance and maintenance risk borne entirely by the developer

Coordination with HAREDA: HAREDA will facilitate site access, government department coordination, and DISCOM net metering approvals on behalf of the selected RESCO developers — a significant operational advantage given Haryana's regulatory environment.

PPA structure: Selected developers sign long-term Power Purchase Agreements directly with the respective Haryana state government departments, at the tariffs discovered through the competitive bidding process.

Bidding Structure by District

The 30.93 MW capacity is distributed across the 20 districts, with each district forming a separate bidding category. Tender fees vary by district size:

The district-specific bidding structure — with separate categories for each geography — allows developers to bid selectively for districts where they have the strongest presence, cost advantage, or prior experience. It also enables smaller regional developers (who may have strong relationships in specific Haryana districts) to compete against national players in their home markets.

Bidding Timeline

The April 22 bid deadline has passed — this tender's evaluation and award process was underway or completing as of June 2026. RESCO developers who won allocations will be in the process of site surveys, structural assessments, and DISCOM net metering applications across the 20 Haryana districts.

Haryana's Solar Policy Context

Haryana is one of the most solar-active states in North India, driven by:

HAREDA (Haryana Renewable Energy Development Agency): HAREDA has been proactively facilitating both utility-scale and distributed solar development in Haryana. Its role as nodal facilitator in this NHPC tender demonstrates the state's collaborative approach to central agency solar procurement.

HERC open-access regulations: The Haryana Electricity Regulatory Commission (HERC) governs open-access solar for large industrial consumers. In 2026, HERC made significant decisions on open-access surcharges — see our detailed post on HERC open-access surcharge 2026 for a comprehensive analysis.

PM Surya Ghar Yojana: The NHPC tender is linked to PM Surya Ghar Muft Bijli Yojana, India's flagship rooftop solar programme. This linkage means the projects benefit from MNRE's programme infrastructure (technical standards, monitoring requirements) and may also benefit from potential subsidy support.

HAREDA's 6,000 MW target: Haryana's draft solar policy targets 6,000 MW of solar capacity by 2030, including 1,600 MW from rooftop solar. The NHPC 30.93 MW tender is part of the accelerated push to install rooftop solar on Haryana's 50,000+ government buildings — a major untapped resource.

What This Means for Haryana Solar Buyers

For Haryana government departments and institutions, the NHPC tender provides a streamlined, HAREDA-facilitated pathway to zero-capital rooftop solar. The RESCO model eliminates budget requirement for capital expenditure while delivering electricity bill savings from Day 1 of commissioning.

For industrial solar buyers in Haryana — particularly in Faridabad, Gurugram, Manesar, and Panipat industrial clusters — this tender is a signal of the state government's commitment to solar mainstreaming. While the tender itself targets government buildings, the resulting EPC activity, module procurement, and HAREDA-DISCOM coordination will strengthen the entire Haryana solar ecosystem.

For EPC companies and RESCO developers in Haryana, the district-by-district bidding structure creates opportunities to compete selectively based on local presence. Companies with strong relationships with Haryana state departments, existing DISCOM net metering approvals, and installation teams in specific districts are best positioned.

Sun Wave Technologies operates from Faridabad and serves industrial clients across the Haryana-Delhi NCR corridor.

What is NHPC REL's role in this tender vs HAREDA?

NHPC REL (NHPC Renewable Energy Limited) is the central procuring agency that designs, floats, and manages the tender on behalf of the Government of India's PMSG-MBY scheme. HAREDA (Haryana Renewable Energy Development Agency) acts as the state-level nodal facilitator, coordinating with Haryana government departments, DISCOM for net metering approvals, and site access. The selected RESCO developers sign PPAs with individual Haryana government departments.

Is Faridabad included in this tender?

Yes — Faridabad is explicitly listed as one of the 20 Haryana districts covered, and is categorised as a "larger district" with a tender fee of Rs 5,000 and EMD of Rs 3,80,000.

Can private industrial companies also use the NHPC RESCO model?

The NHPC tender specifically targets government-owned buildings. Private industrial companies have other options — including third-party RESCO agreements with private solar developers, open-access procurement from independent power producers, and captive solar installation. For a comparison of these models, see our guide on CAPEX vs OPEX vs Open Access solar in India.
