The Delhi Electricity Regulatory Commission (DERC) had issued regulations on net metering for renewable energy in September 2014. The regulations allow registered customers of discoms to install renewable energy systems and the discoms will allow connectivity of these systems to their network through net meters.
A Tata Power Delhi Distribution Limited (TPDDL) spokesperson said the surge in domestic (residential) sector in this regard has been visible since 2017.
"The surge in domestic count can be observed since 2017, which is credited to the Ministry of New and Renewable Energy (MNRE) subsidy scheme in Phase-I under which a customer is entitled to flat 30 per cent subsidy on solar plant cost," he said.
The TPDDL has so far installed nearly 1,000 rooftop solar net metering connections.
"In 2019-20, a total of 374 rooftop solar net metering customers were added that included 245 in domestic category," the spokesperson said.
The current cumulative installed capacity is 33.7 MW which is intended to be increased to 40 MW in the next two years, he added.
A BSES spokesperson said the response to rooftop solar net metering has been "incredibly encouraging" and consumers across categories have warmed up to the concept in a big way.
The BSES discoms -- BRPL (2,197 connections) and BYPL (541 connections) -- have a total 88 MWp solar load at present. In the current year (FY 2020-21), BSES is likely to energise around 1,000 rooftop solar connections, he said.
BSES has energised rooftop net metering connections ranging from a sanctioned load of 1 KW to over 1,600 KW. Consumers have begun to see the benefits of rooftop solar net metering and how it reduces their electricity bills. This is reflected in the varied consumer mix," a BSES official said.
If the annual savings accruing to consumers in different segments are analysed, they are saving over Rs 62 crore annually, he said.
"Every KW of rooftop solar generates about 100 to 120 units of electricity every month and the cost of the system can be recovered within 3.5 to 4 years," the official said.
In solar net metering systems, the consumers can sell the surplus electricity after consumption, and get paid by the discoms.
The MNRE subsidy on capital cost is between 20 per cent to 40 per cent (up to 10 kW) for residential consumers and 20 per cent (upto 500 kW) for group housing societies, depending on the capacity of the solar plant, the BSES official added.
