Activities in solar energy have been increasing in Bihar. Last financial year BREDA had invited bids for installing 40 MW rooftop solar plants across the state. This financial year according to Mercom India BREDA has announced RFP to develop 15 MW solar rooftop plants. The developers have to install these solar power plants on government buildings and health departments. BREDA is the nodal agency of Bihar that monitors the development of renewable energy projects in the state. Also, there is another 2 MW rooftop solar that will come up in Bihar Sharif. This project is a part of the smart city. BREDA projects will be developed under RESCO mode whereas smart city projects will be on a turnkey basis. The solar plants will be connected with the grid through the net-meter arrangement.
In the 15 MW project, a bidder has to bid for a minimum capacity of 1 MW. Small rooftop solar capacities do not offer the benefit of economies of scale to developers. Even if the developers aggregate the size the capacities remain scattered keeping the tariffs on the higher side.
While Bihar has many ground-mounted utility-scale solar energy projects rooftop solar projects are very few.
Possible rooftop solar cost in Bihar:
To determine the cost solar developers will take a reference from the BERC order on the feed-in tariff for solar energy. This order also includes rooftop solar projects. For FY 2018-19 BERC has fixed the cost of 1 MW solar power plant to INR 4.23 Cr and the tariff is INR 4.17. Plant installers and developers cannot quote anything higher than these figures.
It will indeed be a breakthrough if these solar projects are able to breach INR 4. Additionally, Bihar will also have to think about more favourable regulations on lines of Uttar Pradesh for propelling solar projects.
