## Utility-Scale Green Power Procurement for HT Consumers Many energy-intensive corporations face a common hurdle: limited rooftop surface area relative to massive multi-megawatt power requirements. Open Access solar parks solve this structural challenge by allowing enterprises to procure clean electricity generated offsite and wheeled seamlessly through the state transmission grid. ### Group Captive vs. Third-Party Open Access Understanding the regulatory distinction is essential for optimizing procurement economics: 1. **Group Captive Model**: * Consumers hold a minimum 26% equity stake in the dedicated special purpose vehicle (SPV). * Must consume at least 51% of the aggregate power generated. * **Key Advantage**: 100% exemption from Cross-Subsidy Surcharge (CSS) and Additional Surcharge (AS), yielding maximum savings. 2. **Third-Party Open Access**: * Bilateral PPA signed directly with an independent solar park developer. * No equity investment required from the consumer. * Standard wheeling charges and state DISCOM surcharges apply. ### Land Acquisition and Evacuation Infrastructure Developing a 50 MW solar park demands meticulous site selection, flood-risk assessment, and high-voltage grid substation proximity. Niva Ecotech handles the entire lifecycle—from barren land aggregation and DISCOM bay clearances to 132/220 kV transmission line construction. ### Summary With the Ministry of Power's Green Energy Open Access (GEOA) regulations reducing the contracted capacity threshold to 100 kW, open access solar has become accessible to mid-size industrial consumers nationwide.
