Open access solar in Karnataka delivering power over the grid

Open access solar in Karnataka just received global recognition. In its India Renewable Energy Market Report 2026, the International Energy Agency named Karnataka among five states where open-access renewable projects are growing strongly, alongside Gujarat, Maharashtra, Tamil Nadu and Rajasthan, according to Saur Energy reporting dated November 3, 2026.

If you run a factory, warehouse or commercial building in Karnataka, this guide explains what open access solar is, who can explore it, and what is changing in 2026.

What Did the IEA Say About Open Access Solar?

The supplied article says the IEA sees open-access renewable projects as an important complement to government auctions, especially in states with high industrial electricity demand such as Karnataka. It also expects India's solar capacity to exceed 350 GW AC by 2030, with distributed segments such as rooftop and open access growing faster than large utility projects.

Key points in the supplied report summary include:

What Is Open Access Solar?

Open access solar allows a business to procure solar power from a plant located elsewhere in the state, using the public electricity network to move the power. The customer pays the contracted solar price plus the applicable grid and open-access charges instead of relying only on the full DISCOM tariff.

A simple analogy is buying directly from a farm and using the public road for delivery: the solar plant produces the electricity, the grid carries it, and the buyer pays for the power plus the applicable network charges.

There are three common commercial structures:

ModelHow it worksUpfront investmentBest for
Third-party open accessYou sign a long-term PPA with a solar developerNoneBusinesses that want savings without owning the generation asset
Group captiveParticipating consumers together own at least 26% equity and consume at least 51% of plant outputSmall equity stakeHigher-volume consumers willing to invest for the captive structure
CaptiveYour business owns the plantFull project investmentVery large consumers with capital and enough demand to use the plant's output

How Fast Is Open Access Solar Growing in India?

The supplied article describes record growth in 2026. It cites Mercom India's Q2 and first-half 2026 report, summarised by now.solar / pv magazine, as showing about 6 GW of open-access solar added in the first half of the year, up 42% from the same period in 2025. Q2 alone added a record 3 GW.

Why Is Karnataka a Good State for Open Access Solar?

Karnataka combines strong renewable resources, a mature developer ecosystem and high commercial and industrial electricity demand. The supplied source also cites comparatively low wheeling charges for HT consumers.

Its October 2026 Qbits Energy reference places Karnataka wheeling charges for HT consumers at about ₹0.29 per unit, compared with approximately ₹0.63 in Gujarat and ₹1.03 in Tamil Nadu for FY 2026–27. Because grid charges are tariff-sensitive, businesses should verify the current KERC order when modelling a live project.

The same supplied guide notes a regulatory roadmap toward phasing out cross-subsidy surcharge in Karnataka by FY 2029.

Karnataka is also planning much more renewable supply. Read our guide to Karnataka's 30 GW renewable-energy push.

Who Qualifies for Open Access Solar in Karnataka?

The supplied source cites KERC's draft 2026 open-access rules as proposing a minimum sanctioned load or contract demand of 100 kW for most consumers. Captive consumers are described as exempt from this minimum.

A quick self-check:

Eligibility caution: the 100 kW threshold comes from the June 2026 draft regulations cited in the supplied article. Confirm the final notified KERC rules before applying or signing a PPA.

What Is Changing in Karnataka's Open Access Rules in 2026?

Karnataka is moving toward a General Network Access framework. The supplied article says KERC's June 2026 draft would replace older open-access categories with long-term GNA and short-term T-GNA, introduce a digital State Open Access Registry and distinguish between solar-hour and non-solar-hour access.

The draft proposals described in the supplied source include:

For the storage angle, see our guide to solar with battery storage in Karnataka.

Draft-rule caution: this page preserves the supplied source's description of the June 2026 GNA framework as a draft. Do not assume the proposed provisions are final without checking the notified KERC regulations.

The supplied article also says the ALMM List-II requirement for open-access projects was deferred to the end of 2026. Project teams should confirm the module and cell rules applicable to the planned commissioning date.

If you are comparing providers, choose one that tracks these rule changes and handles the filings end to end. Panchami is a solar company in Karnataka focused on commercial solar, open access and group captive projects.

Frequently Asked Questions

What is open access solar in Karnataka?

It allows a business to procure solar power from an off-site plant using the public grid. The customer pays the contracted solar rate plus the applicable grid and open-access charges.

What is the minimum load for open access in Karnataka?

The supplied source cites KERC's draft 2026 rules as proposing a minimum of 100 kW sanctioned load or contract demand for most consumers, with captive consumers exempt. Confirm the final notified rule before applying.

How much can open access solar save?

Savings depend on tariff category, load and project structure. As an example, the supplied Panchami draft uses a group captive delivered rate of about ₹4.73 per unit with a small equity stake, compared with ₹7 or more per unit for many HT consumers after charges. It positions savings of up to 30% or more as possible, subject to the actual bill and applicable charges.

What is the difference between open access and group captive?

In third-party open access, the developer owns the plant and the business buys the power. In group captive, participating consumers together hold at least 26% equity and consume at least 51% of the plant's output to maintain captive status.

Why did the IEA mention Karnataka?

The supplied source says the IEA identified Karnataka among five states where open-access renewable projects are an important complement to government procurement because of strong industrial electricity demand. The other states named were Gujarat, Maharashtra, Tamil Nadu and Rajasthan.
