Open Access or Offsite Solar

Installed outside the premises and uses the existing grid to wheel the power

Offsite solar, known as Open Access in India, allows you to purchase power directly from the market (through the grid). Since, you can select your power supplier, there is a significant reduction in your power costs. To qualify, a consumer needs to meet requirements that have been laid down by each state’s electricity regulatory commission. The most common requirement is that you need to have a minimum contract demand and sanctioned load of 1MW. In addition, you should have a constant billing demand, which amounts to 70% of your contract demand.

Going for Open Access includes various charges like wheeling, transmission, SLDC (State Load Despatch Centre) fees, etc that must be paid for each unit of electricity fed to the grid. Cross-subsidy and additional surcharge are generally applicable, and this might vary from state to state. These charges can vary year to year.

There are three open access policies you can choose from to go for an offsite solar installation.

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.
