With no batteries in the system, this solar power plant on the Secretariat supplies 50kw electricity to the national grid.

A boost to green power

Private company sets up solar plant on Secretariat roof to supply power

The government is introducing the first ever feed-in-tariff system, a mechanism designed to accelerate investment in power generation from renewable sources, and it is allowing companies to commercially install solar plants on large government buildings. Under the initiative, Rahimafrooz Renewable Energy Ltd (RREL) has installed a battery-free solar power plant on the roof of Bangladesh Secretariat building-2, on over 7,000 square feet of space.

With a 20-year contract between Rahimafrooz and Dhaka Power Distribution Company, the plant is generating 50 kilowatt electricity and feeding it to the national grid. Fifty kilowatt power is enough to run a hospital or a commercial or an office building like the secretariat.

The feed-in-tariff (FIT) system is a concept popular in the west for promoting expensive green power alongside conventional power generation. The system guarantees the renewable energy producer electricity tariff higher than the existing rates. It also offers cost-based compensation for renewable energy producers,             providing price certainty and long-term contracts that help finance projects.

The tariff for this power is pretty high, Tk 19.95 per kilowatt hour, which is four to five times costlier than that generated by local gas-fired power plants.

But during the day the plant saves all fuel cost that would otherwise have been required and the maintenance cost is minimal.

“This plant would generate 73 megawatt hours electricity a year and cut carbon emission of approximately 1,000 tonnes in the next 20 years,” said Munawar Misbah Moin, managing director of RREL.
