Gujarat plans to deploy advanced Static Synchronous Compensator (STATCOM) systems at seven additional substations in the state following the successful implementation at the Timbdi substation in Gir Somnath district. This initiative aims to bolster the state’s power grid, enhance voltage stability, and ensure a continuous electricity supply, especially in areas with high agricultural demand.
The first STATCOM with a ±120 MVAR capacity was installed at the 220 kV Timbdi substation in Gir Somnath district on March 5, 2019, by Gujarat Energy Transmission Corporation Limited (GETCO). This made GETCO the first state transmission utility in India to adopt STATCOM technology.
Described as a “smart voltage stabiliser,” the system continuously monitors grid conditions and promptly reacts to fluctuations by providing or absorbing reactive power to maintain voltage stability and uninterrupted power flow.
Officials highlighted Gujarat’s transformation from facing power shortages to becoming a self-reliant state in the energy sector, attributing this progress to reforms initiated under the leadership of current Prime Minister Narendra Modi. Initiatives like the ‘Jyotigram Yojana’ ensured round-the-clock electricity supply in rural areas, setting a benchmark for other states to follow.
The need for STATCOM technology arose due to significant electricity demand fluctuations across sectors, particularly in agriculture, posing challenges in maintaining voltage stability and power quality in various regions. At the Timbdi substation, voltage instability was a persistent issue due to the lack of nearby power generation sources and a single-circuit transmission link.
The STATCOM system now operates in real time to balance the grid under varying load conditions, regulate power factor, reduce over-voltage, and prevent sudden voltage drops. This technology has not only eased the load on the transmission system but also decreased power losses and enhanced equipment safety.
The installation of STATCOM systems has benefited consumers in Gir Somnath, Junagadh, Amreli, and neighboring areas, particularly farmers, by enhancing the reliability and quality of electricity supply for rural and industrial purposes.
Following the success at Timbdi, the government plans to install ±125 MVAR capacity STATCOM systems at six existing 220 kV substations and the upcoming 400 kV Dholera-2 substation. This expansion is expected to further fortify Gujarat’s power infrastructure and ensure a dependable and high-quality electricity supply statewide.
