Atlanta Electricals has started in-house design and certain material ordering for its first 765 kilovolt (kV) reactor, targeting production in Q4 FY27 after sanctions-related constraints prevented its proposed international technology partnership from progressing. Management expects reactor completion and testing between Q4 FY27 and Q1 FY28.

Results, valuation, peers and who's buying, in one view.
Why is Atlanta Electricals developing a 765 kV reactor in-house?
Atlanta Electricals is proceeding with internal development because its proposed international technology partnership could not advance because of international sanctions-related constraints. Management said it remains open to a suitable partnership if circumstances improve, but its engineering team had already begun the first 765 kV reactor’s design and certain material orders by the Q2 FY27 call.
The 765 kV programme is separate from Atlanta Electricals’ nearer-term 400 kV transformer project. Manufacturing of its first 315 megavolt-amperes (MVA) 400 kV-class transformer began on October 26 after delays in receiving critical components, while the 765 kV reactor remained at the design and material-ordering stage.
Atlanta Electricals said the two programmes will run in parallel at different facilities, with 765 kV development in Unit 5 and 400 kV work in Unit 4. Management therefore said it does not expect the in-house reactor initiative to stop the 400 kV programme, although it did not disclose completed reactor design, manufacturing or testing as of Q2 FY27.
Will Atlanta Electricals need custom designs for 765 kV reactors?
Atlanta Electricals said its 765 kV reactor and interconnecting transformer products will follow specifications standardised through the Central Electricity Authority, or CEA. Management said CEA standardisation applies to 400 kV and 765 kV transformers and reactors, making products manufactured to those guidelines acceptable to Power Grid and other Indian customers.
An analyst asked whether Atlanta Electricals would need to work directly with Power Grid to align its 765 kV designs or obtain customer-specific certification. Management said the applicable CEA specifications are standardised, rather than describing a separate customised design requirement for each customer in the discussion.
The specification framework does not confirm an order. Atlanta Electricals did not disclose a named Power Grid contract, a customer approval date, pricing or a commercial order for its planned 765 kV reactor during the Q2 FY27 call.
When could Atlanta Electricals commercialise higher-voltage products?
Atlanta Electricals expects its 400 kV transformer to contribute commercially in Q4 FY27, subject to successful short-circuit testing and necessary approvals in Q3 FY27. Its 765 kV reactor has a later timetable, with production targeted to begin in Q4 FY27 and completion and testing envisaged between Q4 FY27 and Q1 FY28.
The company placed advance purchase orders for long-lead components and developed alternate supplier arrangements after component delays affected the October 26 start of the 315 MVA, 400 kV transformer. Management presented these steps as measures to reduce similar procurement delays in subsequent higher-voltage manufacturing.
Atlanta Electricals reported Rs 184 crore of 400 kV-class orders in its order book and said execution had begun. That disclosed backlog provides a current higher-voltage order reference, but it is separate from the first 765 kV reactor and does not establish the value or timing of future reactor orders.
Atlanta Electricals’ Rs 3,196.97 crore order book at September 30, 2026 was 54.5% higher year on year and above Rs 3,116.63 crore as of June 26, 2026. New orders booked during Q2 FY27 were about Rs 421 crore, while commodity-price volatility delayed some finalisation of tenders where the company had emerged as the lowest bidder.

How is Atlanta Electricals shifting its order focus?
Atlanta Electricals said 400 kV and above will become a greater order focus after it develops the 400 kV prototype, while it will continue pursuing 220 kV and below business. Management described lower Q2 FY27 order intake as a conscious decision because existing orders in the lower-voltage categories provided about 1.5 years of visibility.
Management said an order book of more than Rs 3,000 crore was sufficient for its 220 kV-and-below visibility period. It said larger 400 kV-plus orders could provide longer visibility and higher order values, but it did not say the company would cease bidding for lower-voltage transformer orders.
The planned shift coincides with uneven facility utilisation after heavy rainfall disrupted operations and dispatches during Q2 FY27. Unit 1 at Anand operated at 60% utilisation, Unit 2 at 40%, the Bengaluru plant at about 90%, the Vadodara facility at about 30%, and the Jambusar 765 kV facility at about 7% to 8%.
Finished goods awaiting dispatch were about Rs 180 crore at September 30, 2026, following weather-related disruption. Management said about 70% of these deferred deliveries had been dispatched during October and expected utilisation to increase in the second half of FY27 as customer-site activity resumed.
What capacity investments support Atlanta Electricals’ plan?
Atlanta Electricals expects to commission its dedicated inverter-duty transformer, or IDT, facility before the end of Q3 FY27. The plant is expected to add about 5,000 MVA of capacity with planned capital expenditure of Rs 65 crore and will move 33 kV IDT production out of Unit 2.
Moving 33 kV IDT production is intended to release Unit 2 capacity for 66 kV and 132 kV products. The IDT facility’s civil construction was complete and machinery installation was under way at the time of the call, leaving commissioning before the end of Q3 FY27 as the next disclosed milestone.
A separate tank-and-radiator backward-integration project through AE Components has planned capital expenditure of about Rs 193 crore and a commissioning target of October 2027. Atlanta Electricals said the layout and machinery requirements were finalised and the ground-breaking ceremony completed for the project, which is intended to improve supply-chain reliability and manufacturing efficiency.
Management said the capex then planned would be funded mainly through internal accruals, while long-term bank debt had been tied up but not drawn. It said there was no other major capacity-expansion project planned beyond the Rs 65 crore IDT facility and the Rs 193 crore tank-fabrication project, aside from smaller staff-accommodation works.
Conclusion
Atlanta Electricals is using internal engineering and standardised CEA specifications to continue its entry into 765 kV products after its proposed overseas partnership encountered sanctions-related constraints. The parallel Unit 5 and Unit 4 development routes, alongside Rs 184 crore of 400 kV orders already in the book, link the reactor programme to the company’s broader move toward higher-voltage transmission equipment.
The next disclosed milestones are Q3 FY27 short-circuit testing for the 315 MVA, 400 kV transformer and potential commercial contribution in Q4 FY27, subject to approvals. Atlanta Electricals also targets 765 kV reactor production in Q4 FY27, with completion and testing extending into Q1 FY28, while its Rs 65 crore IDT plant is scheduled for commissioning before the end of Q3 FY27.
