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.
