The sale of solar power from consumers’ end to the national grid under the Net Metering System (NMS) is growing fast. The sale volume has reached to 8.213 MW in May, 2019 which was 4.24 MW in last February, 2019 as per Power Division statistics. The numbers of consumers was 359 in May, 2019 which was 179 in February last.
The sale was started in the last quarter on July 28, in 2018, when the Power Division unveiled the Net Metering Guideline to buy rooftop solar power from consumers.
As per guideline, any consumer can set up a rooftop solar panel system, covering up to 70 percent capacity of the sanctioned load and sell the additional or unconsumed solar power through a special metre under an exchange arrangement. Consumers can use their own solar power alongside that of the national grid. However, on holidays, when solar power is not used, they can sell power to the national grid. On working days, they can preserve their solar power at the grid, and sell it to their power supply company, or take it back for consumption.
At the end of the month, bills are adjusted based on consumption and sale of solar power to the utilities. Consumers are paid by the distribution company at a bulk rate if the sale exceeds the consumption.
The six utilities purchasimg solar powers are, Power Development Board (PDB), Dhaka Electric Supply Company (Desco), Dhaka Power Distribution Company (DPDC), Rural Electrification Board (REB), West Zone Power Distribution Company Ltd (WZPDC), and Northern Electricity Supply Company Ltd (Nesco).
As per May statistics, REB is leading the chart by buying 6.260 MW of unconsumed solar electricity from its 65 consumers across the country. DPDC purchased 862.5 kilowatt from 94 consumers, Nesco purchased 368 kilowatt from a single consumer, WZPDC bought 328.86 kilowatt from 33 consumers while PDB purchased 259.85 kilowatt from 75 consumers and Desco 138.26 kilowatt from 91 consumers.
The committee headed by power secretary is now planning to motivate the industrial consumers to set up rooftop solar power plants on their industries and take its benefit by selling their unconsumed power to the national grid.
