Off-site/Open Access Solar

Access clean energy without roof or land constraints through our open access solar solutions. We facilitate power purchase agreements (PPAs) that allow you to source renewable power from remote solar parks, ensuring predictable costs and regulatory compliance.

Power-as-a-Service (OPEX Model)

Adopt solar with zero upfront investment through our OPEX (Power-as-a-Service) model. We own, operate, and maintain the solar plant, while you pay only for the energy consumed—unlocking long-term savings and freeing up capital for your core business.

Energy Storage Solutions

Future-proof your energy strategy with advanced battery energy storage systems (BESS). Our offerings include standalone and integrated storage for grid services, commercial dispatch, and peak shaving.

  • Technology: Lithium-ion (LFP) and emerging chemistries
  • Applications: Frequency regulation, peak shaving, voltage support, EV charging hubs, and ancillary services
  • Business Models: EPC (customer-owned) or OPEX (energy-as-a-service)
  • Customisation: Solutions for C&I, utility-scale, and EV charging deployments

Government Policies

Under this policy, the solar power plant is set-up exclusively for the use of the consumer only. You must have a minimum 26% equity stake, for the project to qualify under captive open access. The remaining 74% can be funded through an external investor. However, an investor may ask for a lock-in period of a minimum 10-15 years.
The power plant is set-up exclusively for the use of a group of consumers only and a minimum of 51% of the power generated must be consumed by the specified consumers. You must cumulatively own a minimum 26% equity stake for it to qualify under group captive open access. The remaining 74% can be funded through an external investor. However, an investor may ask for a lock-in period of a minimum 10-15 years.
You can purchase renewable energy from any renewable energy producer. There is no requirement for a consumer to invest in owning an equity stake, resulting in zero investment. Moreover, a consumer and producer can decide on the tenure of agreement which can be as short as three months, to 10 years or more.
