According to NTPC , the 230MW Ettayapuram solar PV project is being developed under the Central Public Sector Undertaking (CPSU) scheme Phase-II Tranche-I of the Ministry of New and Renewable Energy. 

As per the conditions in the CPSU scheme, the project employs domestic photo-voltaic modules and cells and receives the Viability Gap Funding from the Ministry, the company added.
