Open Access & Group Captive Solar

Not every industrial or commercial consumer has the roof or land area for on-site solar. Open access and group captive structures let a facility procure power from a solar project built elsewhere, through regulatory routes that allow direct power procurement outside the standard discom supply.

We coordinate the process between consumers, project developers and the regulatory steps involved, so facilities without on-site space can still move to solar-sourced power.

How the power reaches you

Under open access, solar power is generated at a plant elsewhere, injected into the grid, and wheeled to the consumer's connection. The consumer's energy account is credited according to the applicable scheduling, settlement and — where permitted — banking rules. Check banking provisions under current state regulations.

Because the plant does not need to be on the consumer's premises, this route suits facilities with high consumption and little usable roof or land.

Costs to account for

The landed cost of open access power is not just the generation tariff. Depending on the state and the arrangement, it can include transmission and wheeling charges, cross-subsidy surcharge, additional surcharge, banking charges and scheduling costs. Check each of these with the relevant state electricity regulatory commission.

A meaningful comparison sets that landed cost against the facility's current discom tariff for the same consumption profile, not against the headline generation price.

The group captive structure

In a group captive arrangement, consumers hold equity in the generating company and consume a minimum share of its output, as defined in the Electricity Rules. Meeting those thresholds can change which surcharges apply. Check current ownership and consumption thresholds.

Because compliance is assessed over time, group captive structures need careful setup and ongoing monitoring — not just a one-time agreement.

What We Do Directly

  • Assessment of a facility's consumption profile against open access or group captive eligibility
  • Coordination with project developers who have available capacity
  • Guidance through the regulatory and documentation process involved in each route
  • Ongoing coordination between the consumer and the power-generating project

Delivered Through Qualified Partners

  • Generation of the solar power itself, at a project developed and operated by a qualified partner
  • Technical and metering infrastructure at the generation site
  • Grid-level scheduling and compliance processes

We coordinate execution through qualified EPC and delivery partners rather than building or manufacturing in-house.

Process

  1. 01Review the facility's consumption, connected load and current tariff
  2. 02Determine eligibility and the appropriate route — open access or group captive
  3. 03Identify project capacity to match the facility's requirement
  4. 04Coordinate the regulatory and documentation process
  5. 05Support the transition to solar-sourced supply and ongoing coordination

Who It's For

  • Industrial consumers with significant electricity consumption but limited on-site space
  • Commercial or institutional consumers seeking a lower-cost or renewable power alternative to standard discom supply
  • Multiple facilities under common ownership considering a shared (group captive) solar project

Documents & Inputs Needed

  • Recent electricity bills and connected load details
  • Facility ownership structure, particularly for group captive arrangements
  • Preferred contract tenure and capacity requirement

Deliverables

  • Eligibility and route assessment (open access or group captive)
  • Matching with available project capacity
  • Coordination through regulatory documentation
  • Ongoing point of contact through the supply arrangement
