Italy-headquartered FIMER has installed its PVS980-58 2MVA central inverter to power the country’s largest single-site solar power plant, at Rewa in Madhya Pradesh.
The Rewa ultra mega 750-mw solar park is predicted to reduce carbon emissions by up to 1.5 million tons of CO2 per year. It consists of three solar generating units with a capacity of 250MW each and spans 1,500 ha of land.
FIMER has supplied 188 mw out of total 750 mw through Mahindra Susten for Mahindra Renewables.
The Rewa solar park, it may be recalled, was formally inaugurated by Prime Minister of India, Narendra Modi, on July 10, 2020.
Developed and built by Rewa Ultra Mega Solar Ltd, the solar park will supply energy to the Delhi Metro Rail Corporation. It is a joint venture between the Madhya Pradesh Urja Vikash Nigam Ltd and the Solar Energy Corporation of India.
Mahindra Susten, one of India’s leading IPPs and EPC companies, played a key role in executing and delivering the project within two years. Commenting on the success of the project, Rakesh Singh, CEO for Utility and C&I (commercial and industrial) at Mahindra Susten explained: “One of the major challenges we faced during the execution of this project was the hard strata of the land. The land was not conducive for digging cable laying trenches. So, the engineering team devised an innovative method for cable laying: the all-terrain cable tray, which makes use of the vertical posts erected for the module mounting structure. This is the first-ever solar PV (photovoltaic) project to use this innovative cable laying method.”
Following the acquisition and integration of ABB’s solar inverter business in the first quarter of 2020, and under the umbrella of the renewed FIMER brand, the newly-acquired solar inverter portfolio continues to carry the ABB brand under trademark licence agreement.
FIMER’s chairman, Filippo Carzaniga, said: “We are proud to have played a key role in making Indian’s largest solar park such a success. Our solutions are designed to deliver outstanding performance under extreme conditions. This is a great example of innovative design in operation, with our long-lasting inverter helping to maintain uptime at this large PV plant, and more importantly, reduce carbon emissions and energy wastage for future generations.”
Given the extreme weather conditions in Rewa, where average temperatures can regularly exceed 40°C, performance under hot conditions was also key to the success of the project.
FIMER’s PVS980-58 2MVA was specifically suited for the site and the harsh climate conditions. The inverter features a unique self-contained patented cooling system, which is designed for demanding applications and harsh environments, cutting maintenance costs and ensuring outstanding endurance.
“We chose FIMER because the inverter was the best suitable model as per our simulation results. With a block size of 4MW design we achieved lower DC losses and higher generation with 1500V technology. We were satisfied at the prospects of long-term service and dedicated support from a reliable brand having decades of experience,” added Rakesh Singh.
