Delhi Power regulator DERC has formulated guidelines for the minimum transformer-level capacity that must be offered by consumers for connectivity to the renewable energy system and other procedural requirements. This comes a month after Delhi electricity Regulatory Commission started the process for letting power consumers become generators of renewable energy. The commission also declared tariffs for solar power generation which will be the average power purchase costs for the whole year.
Not less than 20% of the rated capacity should be offered so that the discom can connect the renewable energy system for net metering by the respective distribution transformer. This means that the transformer must have at least 20% connectivity. The commission said it would assess the DT level capacity through an independent agency to protect the consumers' interest. "Solar power connectivity will be decided on the basis of the transformer's capacity," said an official.
The solar tariffs will be the average cost of power for the whole year that is procured from several sources, including thermal and gas. For FY 2014-15, the tariffs will be Rs 4.75-Rs 5 per unit. The average power purchase costs are always declared at the beginning of the financial year and then trued up towards the year-end," said chairman P D Sudhakar. Chances of consumers Delhi selling solar power to the grid, are not that high as solar generation will be possible only during very sunny days.
"Most renewable energy generators will use the solar power for their own consumption. If they still export any power to the grid, the discom will pay the consumer on the basis of the tariff set as the annual average cost of power. The consumer will get due energy credits in their next power bill. At the end of the financial year, any pending energy credits will be paid to the consumer," added Sudhakar.
With the final set of guidelines issued, consumers can now begin to become renewable energy generators."The connectivity shall be provided on a first-come-first-served basis subject to a feasibility analysis, including operational and capacity constraints. For initial application, a fee of Rs 500 has been prescribed," say the new guidelines. The net metering regulations outline how people can generate renewable energy on their premises and then reduce their electricity bills through the amount of power they supply to the grid.
DERC officials said the idea was to make consumers independent power producers. "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. If they draw less, they will be given energy credits in the next billing cycle. To become generator, you will have to apply to your area's discom. The discom will allow the connection after analysing the transformer capacity.
