Demystifying Captive Open-Access Solar for Commercial & Industrial Power Consumers

October 13, 2026 2 min read

High-energy industrial consumers—such as steel plants, chemical processing units, textile factories, and large commercial complexes—frequently face a common hurdle: limited roof or land space at their factory site. However, rooftop limitations no longer prevent companies from transitioning to solar power. Captive Open-Access Solar enables businesses to establish or invest in off-site solar farms and transmit clean electricity through the state grid to their facilities. 

Consulting with leading solar epc companies in delhi ncr allows energy-intensive enterprises to bypass site constraints and secure long-term power tariff savings. 

  1. Understanding Captive and Group Captive Solar Models

Under Indian electricity regulations, open-access frameworks allow power producers to sell electricity via state and national transmission grids. 

Two primary structures exist for C&I consumers:

  • Group Captive Model: Industrial consumers hold a minimum 26% equity stake in the off-site solar power plant and consume at least 51% of the generated power. This structure exempts consumers from heavy cross-subsidy surcharges (CSS), delivering significant tariff reductions. 
  • Third-Party Open-Access: Businesses sign long-term Power Purchase Agreements (PPA) with solar developers to buy power at a fixed, mutually agreed rate. 

Partnering with an experienced solar energy solution provider simplifies regulatory approvals and equity structuring. 

  1. Significant Tariff Savings and Hedging Against Grid Rate Hikes

Industrial DISCOM tariffs in states like Delhi NCR, Haryana, Uttar Pradesh, and Rajasthan often exceed ₹8 to ₹10 per unit. In contrast, open-access solar power delivered through a captive model can cost significantly less per unit, providing immediate financial savings. 

Key economic advantages include:

  • Long-Term Tariff Lock: Securing fixed, predictable energy costs for 25 years. 
  • Exemption from Surcharges: Group captive models eliminate cross-subsidy and additional surcharges. 
  • Scalability: Powering multiple manufacturing facilities under a single corporate energy agreement. 

Top Rooftop Solar Company in Ghaziabad and Rooftop Solar Company in Delhi firms are increasingly guiding clients toward hybrid rooftop + open-access strategies. 

  1. End-to-End Turnkey Execution by Premier EPC Leaders

Executing a captive open-access project requires comprehensive engineering, land procurement, high-voltage substation setup, and regulatory coordination. Reliable solar panel installers in Noida handle every phase—including ABT metering, state load dispatch centre (SLDC) permissions, and grid wheeling agreements. 

By choosing solar power plant in delhi NCR specialists with a proven track record, enterprises ensure fast project commissioning and maximum plant uptime.

03Who is eligible for open-access solar power in India?

Commercial and industrial facilities with a connected load of 1 MW (or 100 kW in states adopting Green Open Access rules) are eligible to source clean power via open access.

04How much can a business save with Group Captive solar power?

C&I consumers typically save 20% to 40% compared to standard DISCOM commercial grid tariffs, while securing long-term price stability for 25 years.

05Who handles the grid wheeling permissions and approvals?

Leading solar epc companies in delhi ncr manage end-to-end statutory approvals, ABT metering, state load dispatch centre (SLDC) registration, and wheeling agreements with state utilities
