Tata Power Solar said it would be supplying the entire module requirement for a 20-MW project to be built by ACME Solar.
ACME Solar, during the national solar mission bidding process last year, won projects totalling 100 MW.
Of this, 20 MW, under the domestic content requirement policy of the Renewable Energy Ministry (MNRE), should be built using cells and modules manufactured domestically.
ACME Solar is a three-way joint venture between ACME, EDF Energies Nouvelles (EDF EN), the renewable energy arm of French state-run electricity utility Électricité de France S.A., and Luxembourg-based natural resources saving group EREN.
Tata Power said one lakh modules, constituting 60,00,000 cells, needed for the project would be made at it manufacturing facility in Bangalore.
