Delhi took a huge leap in renewable energy generation on Tuesday. Power watchdog Delhi Electricity Regulatory Commission (DERC) announced regulations for net metering of renewable energy, giving Delhiites a chance to become renewable energy suppliers. The regulations outline how people can generate renewable energy in their premises, and then reduce their electricity bills by the amount of power they supply to the grid. The regulations are expected to be enforced within a week.
While the net metering regulations apply to all forms of renewable energy like solar, hydro and wind, in Delhi only solar generation is feasible. Many households and organizations already generate solar power for their own consumption, but the new regulations will allow them to supply to the grid and receive energy credits or adjust the units supplied against their electricity bills.
DERC chairperson P D Sudhakar said, With this, consumers can set up their own solar panels and either supply directly to the grid or use it partially. Whatever you supply to the grid, you can draw back whenever you need it. How much power a person supplies and draws back from the grid will be metered. If they draw more than they supply, the difference will be billed to them. If they draw less, they will be given energy credits in the next billing cycle.
To become a renewable energy generator, a person will have to apply to their areas discom for a connection to the renewable energy system. The discom will then allow the connection after analyzing transformer-level capacity.
Two meters will be installed in the consumers premises a renewable energy meter to measure total renewable energy generated, and a net meter to measure the difference between the power drawn and contributed to the grid. Check meters can be installed by either party at their own cost. Charges for the testing and installation of net meters will be borne by the consumer, and those for the renewable energy meter by the distribution licensee, the regulations state.
Many large-scale power consumers like malls, hospitals, schools and government buildings already generate solar power. The MoEF building in Jor Bagh generates up to 1MW power which it is unable to use. Now it can supply its excess power to the grid and get adjustments in its power bills. We also hope households will opt for renewable energy generation, said a DERC official. For discoms, the advantage is that any renewable energy they source in this way will count towards their renewable power obligations that they have not been able to meet.
