Fimer Supplies Solar Inverters for Mahindra Susten’s BESS Project at Sun Temple Town in Gujarat

Solar inverter specialist Fimer has recently supplied its 1MVA inverters to Mahindra Susten for its Battery Energy Storage System (BESS) installed for the integrated solar energy project at Sun Temple Town in Modhera of Mehsana district in Gujarat.

On August 26, 2021, the project, which was awarded by Gujarat Power Corporation Limited (GPCL) to Mahindra Susten as an EPC, was fully commissioned.

Also, this is the country’s first integrated state of art solar project having one of the largest BESS systems to date under operation in India.

The project is the vision of Prime Minister Narendra Modi to make Modhera Sun temple and Modhera town self-reliant and self-sustainable for their power requirement through solar energy.

Commenting on the development, 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 project has a 6 MW grid connect system with a 6MVA BESS system with an 18 MWh Battery energy storage system.

For the project, Fimer had supplied PCS of rating 1 MVA x 6 nos for BESS application: during solar hours the solar inverter powers the load, and the excess power charges the batteries; additionally, PCS can also support load demand during solar deficit conditions. Fimer PCS is also equipped with Black Start Mode / Grid Forming Mode, during grid failure conditions; Fimer PCS can form the Grid in V/F mode and other sources (inverters) can synchronize to AC bus and start supporting load or charge batteries. If the grid comes back, PCS can operate in the grid following mode and act as backup whenever required. This is the first-time bidirectional converter 1 MW was supplied to the Indian market.

“Modhera Project is one of the prestigious and highly innovative integrated projects executed in the country. Susten is privileged to be the EPC for this project of national importance. The project has a complexity of integrating the solar generation ranging from 1 KW to 6 MW and a 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,” commented Pramod Kalyanshetti, Chief Commercial Officer of Mahindra Susten.
