Tamil Nadu Adjusts Power Procurement Amidst Monsoon-Induced Demand Drop

The state government is recalibrating its power procurement approach to lessen its dependence on costly open-market electricity. This adjustment follows a reduction in electricity demand by about 1,000 MW due to the northeast monsoon.

Electricity minister C T R Nirmal Kumar recently reviewed various factors, including power demand, procurement costs, generation capacity, and monsoon preparedness. The review also addressed measures to resolve complaints regarding power interruptions. Officials plan to modify power purchases based on rainfall and demand fluctuations, particularly during evening peak hours, to avoid high-priced electricity acquisition when demand is low.

Earlier in the week, agreements were signed for the purchase of 3,500 MW at rates between ₹32-37 per unit. The state had anticipated the need for additional power due to previously high demand levels. The daily additional cost for procuring power to meet peak demand can range from ₹5 crore to ₹7 crore. However, power interruptions could lead to significant losses for industries and commercial entities, necessitating a balance between procurement expenses and supply reliability.

Waaree Energies Expands into Battery Energy Storage and Inverter Manufacturing

Waaree Energies is expanding its manufacturing capabilities to include integrated battery energy storage systems (BESS) and inverters. This strategic move follows a visit to the company's Rola and Sarodhi plants in Gujarat by PL Capital, which anticipates substantial top-line growth from these new capacities.

The company commissioned 5.15 GWh of BESS assembly capacity at its Rola facility in July 2026. Equipment installation for a 4 GWh cell manufacturing unit is also underway, with a planned launch in December 2026. The BESS facility aims for an annual throughput of approximately 1,000 containers, utilizing semi-knocked-down kits imported from China.

In Sarodhi, Waaree Energies operates a 4 GW inverter plant, which commenced operations a year ago with a capital expenditure of ₹180 crore. The plant is currently operating at 58 percent utilization across two shifts, with a target to produce 5,000 inverters by December 2026. The company is also pursuing export certifications for its inverter products.

Thorizon and TNO Launch Molten Salt Reactor Materials Program

Thorizon and TNO have launched a new materials program focused on Molten Salt Reactors (MSRs). The initiative addresses the challenge of ensuring structural materials can withstand the hot, corrosive salt and radiation environments present in MSRs over extended periods. MSRs utilize molten fluoride salts as primary coolants at low pressure and offer enhanced safety, efficient fuel use, and the potential to reduce long-lived radioactive waste.

Thorizon's MSR design incorporates sealed cartridges containing the fuel salt, which are replaced every five to ten years. This design limits the exposure of key components to the salt, allowing for inspection and replacement during scheduled cartridge changes. The new program, led by TNO, will generate data and models to confirm design choices, determine cartridge lifetime, and monitor materials during operation. This research will support the licensing of Thorizon's Pioneer demonstrator in Petten, Netherlands, and the commercial rollout of Thorizon One.

Program Details and Collaborations

The program involves an extensive plan for materials characterization, corrosion testing, modeling, and validation. Initial work is underway at Thorizon's facilities in Amsterdam and TNO's laboratories in Petten, directly supporting Thorizon's reactor design, material selection, and licensing process.

Thorizon and TNO plan to collaborate with other organizations in the Dutch nuclear sector, including Delft University of Technology and NRG-Pallas. They also aim to involve international partners such as the French Alternative Energies and Atomic Energy Commission (CEA) and the European Commission's Joint Research Centre. These collaborations are intended to leverage expertise in materials science, molten salt chemistry, irradiation, modeling, reactor engineering, and licensing.

Thorizon, a spin-off from NRG, is developing a 250 MWt/100 MWe MSR for industrial customers and utilities, with construction of Thorizon One planned around 2030. The company collaborates with industry leaders such as Orano, Tractebel, and EDF, and its project has received support from the European Commission and the French government under the France 2030 investment plan. The Thorizon Pioneer, a smaller, non-commercial version of Thorizon One, will validate the reactor core without electricity production and will be the first nuclear molten salt installation operating in Europe.
