RIR Power Secures Overseas Thyristor Order

28 May 2026 CW Team

RIR Power Electronics has secured a large overseas order to supply 120 units of its 5kV silicon-controlled rectifier (SCR) thyristors in the first phase. The order reinforces growing global confidence in the Mumbai-based company’s high-performance semiconductor devices, assemblies and energy management systems.

The company’s 125 mm 5kV SCR thyristors are high-current semiconductor switching devices designed for heavy-power applications requiring very high current handling, short-duration high di/dt pulses and strong reliability. Built with a 125 mm silicon chip in press-pack construction, the devices offer high mechanical reliability, optimised lifetime control, low thermal resistance and strong surge current capability.

The order has been placed by a leading Class I Electrical EPC contractor engaged in turnkey electrification projects for industries and power plants worldwide. RIR Power Electronics said the order is among the largest single orders for its 125 mm pulse power thyristor range and is scheduled for execution by the end of 2026.

N Ramesh Kumar, MD & CEO, RIR Power Electronics, said the company expects to expand such mandates and strengthen partnerships with Class I Electrical EPC contractors. He added that RIR Power Electronics is also setting up a state-of-the-art silicon carbide semiconductor manufacturing plant in Odisha to support India’s semiconductor manufacturing ambitions.

The company’s high-power press-pack thyristors are used in HVDC transmission valves, Static VAR Compensators, medium-voltage soft starters, high-power rectifiers, crowbar protection systems, pulsed capacitor discharge systems, traction and legacy locomotive systems, and defence applications requiring high-energy bursts in short durations. RIR Power Electronics expects stronger business momentum as it broadens its product portfolio and expands its global presence in the power semiconductor industry.

NSW Launches 2.5 GW Renewable Tender And 12 GWh Storage

New South Wales has opened a pair of record tenders seeking two point five gigawatts (GW) of new renewable generation and 12 gigawatt?hours (GWh) of long?duration storage to accelerate its clean energy transition. The generation auction, Tender 8, is the largest launched under the NSW Electricity Infrastructure Roadmap and is being managed by independent consumer trustee AusEnergy Services Limited (ASL). The storage contest, Tender 9, seeks up to 12 GWh of additional storage and follows a decision to unlock an extra 50 per cent of capacity above baseline planning targets. Officials indicated t..

Jharkhand Researchers Develop Eco-Friendly Solar Cell

A team from the Department of Energy Engineering at the Central University of Jharkhand (CUJ) has developed an eco-friendly solar cell that uses a plant-based natural dye extracted from the petals of Mirabilis jalapa (commonly known as Gulabbas or Four O'Clock Flower). The researchers described the work as part of ongoing laboratory studies to explore sustainable alternatives to conventional photovoltaics. The device builds on dye-sensitised solar cell concepts adapted for locally available botanical materials. The lead researcher said the developed solar cell had achieved a highest power conv..

Gwalior Floats Rs 99.8 mn Tender For Two MW Solar Plant

The Gwalior Municipal Corporation has issued a Notice Inviting Tender under a Request For Proposal to appoint an agency to develop a grid-connected solar power project at Manpur. The scheme calls for a two Megawatt AC on-grid ground-mounted solar photovoltaic plant, with a 20 per cent DC oversizing that raises the total DC capacity to two point four Megawatt (MW). The selected developer will be responsible for detailed design, construction and all associated infrastructure works required for grid integration. The original tender document was dated eight June 2024 and was digitally updated in M..
