Italian firm FIMER has revealed that it has supplied its 1 MVA inverters to Mahindra Susten's battery energy storage system (BESS) system and successfully executed the Integrated Solar Energy Project at Sun Temple Town of Modhera, in Gujarat. Awarded by Gujarat Power Corporation Limited (GPCL) as an EPC, the project was fully commissioned on in August last year.
As part of India's first integrated solar project, the BESS is one of the largest till date under operation in the country. It features a 6 MW grid connect system, with 6 MVA and 18 MWh battery energy storage system.
FIMER has supplied 6 units of PCS of rating 1 MVA for the BESS application. During the day, the solar inverter powers the load, and the excess power charges the batteries. PCS can also support load demand during solar deficit conditions.
KN Sreevatsa, Country Managing Director at FIMER India said: "At FIMER, we believe not only in providing tailormade solutions for the customer's maximum benefit, but we also like to "Make a difference" to their lives. We fully support our PM's vision of making small towns and cities self-sustainable and we are glad to be a part of this remarkable project.
The PCS is also equipped with 'Black Start Mode' or 'Grid Forming Mode' for grid failure scenarios. It can form the Grid in V/F mode and other sources (inverters) can synchronize to AC bus and start supporting load or charge batteries.
Once the grid is active, PCS can operate in grid-following mode and act as back-up whenever required. This is the first-time bidirectional converter 1 MW supplied to Indian market, according to the company.
Pramod Kalyanshetti, Chief Commercial Officer of Mahindra Susten, said, "The project has a complexity of integrating the solar generation ranging from 1 KW to 6 MW and battery system of 18MWh. Susten design team had analysed each design aspect thoroughly while running various generation model simulations and concluded on final design. All the equipment's used in the project were analysed considering the reliability and long-term service".
"FIMER had provided us their best service with supply of inverters in our previous projects. Considering the best design fit and their reliability the FIMER PCS of size 6MW is used for our prestigious Modhera project", he added.
