New Delhi: State-run BHEL (Bharat Heavy Electricals Limited) has successfully commissioned a 1.7 MW solar PV plant at Bina in Madhya Pradesh for the Indian Railways. The plant will directly feed power to the traction systems of the Indian Railways. The project is a landmark achievement in the history of solar power, as this is the first time that solar power is being directly used for traction applications. With this, BHEL has achieved direct injection of single-phase 25 KV power to traction substation of Indian Railways.
The project has been jointly conceptualised and developed by BHEL and Indian Railways. BHEL's scope in the project envisaged design, engineering, manufacture, supply, construction, erection, testing, commissioning and O&M-based on the inputs provided by the Indian Railways. The project has been installed and commissioned by BHEL in just 4.5 months from the date of joint land survey with Indian Railways for the Bina location (excluding the time lost due to COVID situation).
This is a pilot project by the company developed on turnkey basis on vacant land of the Indian Railways. The concept to design and engineering was carried out in less than 1.5 months. The R&D, development and manufacturing, was completed entirely in-house at BHEL facilities at Bengaluru, Hyderabad, Jhansi and Bhopal.
Significantly, for the first time, the development of single-phase 850 kW solar inverters and 400 V/25 kV dry type transformers for outdoor duty has been done. Other solar plant equipment such as PV modules, SCADA system and HT switchgear have also been supplied by BHEL's manufacturing units located at Bengaluru and Bhopal, respectively.
"The project is a unique example of joint working of Indian Railways and BHEL in the field of rail transportation. This development marks a major step of merging the advantages of renewable energy in the railway sector in an unprecedented way. With this successful demonstration by BHEL, Indian Railways' objective of turning its huge land bank into captive PV power plants for supporting the Railway traction grid without the support of utilities and the Railways' initiative of 'Go Green' by 2030, will become a reality," said an official statement released by BHEL.
"BHEL is offering EPC solutions for both off-grid and grid-interactive ground-mounted, rooftop, floating solar and canal top solar plants. This is evident from its current portfolio of more than 1 GW of SPV plants. BHEL is also offering space-grade solar panels with high-efficiency cells and space-grade batteries," the statement said.
"BHEL has been contributing significantly to the nation's green initiatives for developing and promoting renewable energy over the past three decades. The company's sustained success and dominant presence in the segment is backed up by a dedicated R&D team, product development groups and a spectrum of high-quality in-house developed PV products ranging from Solar Inverters and Solar Passive Trackers in addition to Solar PV cells and modules," it added.
