Suzlon Energy Ltd. makes a corporate announcement

Updated order book: approximately 6.1 GW. The reported order book had reached 5.7 GW after the 201.6 MW Oyster Renewable order ^[1]. Adding the 378 MW NTPC Green Energy order ^[2] gives a derived total of 6.078 GW, rounded to ~6.1 GW.

Capacity-utilization fit: the order is incremental support for FY26-FY27, rather than FY25. The NTPC announcement identifies a 378 MW Gadag, Karnataka project involving 120 S144 turbines, but does not disclose a project-specific delivery or commissioning date ^[3]. Management had earlier indicated that most of the order book would execute across FY26 and FY27 ^[4].

• Suzlon’s stated manufacturing framework was 4.5 GW of capacity, with 90% loading implying roughly 4 GW of annual supply; management also cautioned that actual utilization depends on customer project offtake and readiness ^[5].
• The 378 MW project represents approximately 9.45% of that implied 4 GW annual supply capacity, derived from 378 MW divided by 4,000 MW.
• It therefore provides useful volume support toward the utilization objective, but does not by itself fill the capacity. Execution will depend on land, evacuation infrastructure and customer readiness—particularly relevant because this is a PSU-linked project.
• For context, Suzlon delivered 1,550 MW in FY25, while its manufacturing capacity was stated at 4.5 GW and fully operational ^[6]. The project was announced after FY25 ended, so it should not be counted as FY25 delivery or FY25 utilization; its economic contribution should fall principally into the subsequent execution cycle.

Yes. The 400 MW Tata Power Renewable Energy order involves 127 S144 turbines rated at 3.15 MW each. It is broader than a turbine-supply contract: Suzlon’s scope includes land acquisition, turbine supply, Balance of Plant, pooling substation, EHV line, installation/erection, commissioning and post-commissioning O&M. ^[7]

Margin comparison

The order should be viewed as a full EPC/DevCo-style contract, not a pure WTG sale. That increases Suzlon’s revenue capture per MW but also brings project-execution costs, working-capital requirements and lower-margin project activities into the scope.

Analytical read-through: the Tata order’s scope is consistent with Suzlon’s recent migration toward higher EPC participation—EPC share increased from 20% to 27% of the order book in Q3 FY26 and reached 32% of Q1 FY27 activity versus 22% in Q1 FY26. ^{[12] [13]} However, recent commentary indicates that project/EPC work can carry a lower margin than pure turbine supply, even though management described the 602 MW DevCo EPC contracts as being on similar commercial terms to prior orders and value accretive. ^[14]

Therefore, the order is scope-positive and strategically more integrated, but the available evidence does not support assuming a margin premium over earlier utility-scale supply contracts. The appropriate benchmark is the recent low-to-mid-teens WTG EBITDA range, while the 23.4% Q1 FY27 WTG contribution margin shows the broader contribution pool before corporate and other operating costs. Exact Tata-order profitability will depend on land, BoP, transmission and commissioning execution; Suzlon has not disclosed those economics separately.

378 MW is materially smaller than Suzlon’s recent quarterly order-intake run-rate. Using quarterly additions as the closest disclosed proxy, the last four reported quarters averaged roughly 883 MW, making the NTPC order approximately 43% of the average, or about 57% smaller.

The comparison is against quarterly order additions, not the average size of every individual contract, because Suzlon has not disclosed a complete contract count for each quarter.

CPSE repeat-order mix

The exact percentage of the current order book represented by repeat CPSE orders is not separately disclosed. Suzlon reports that 84% of its approximately 6.1 GW order book is from the broader PSU and C&I segments, but that category is wider than CPSEs and does not identify repeat business ^[20].

Useful reference points are:

• The 378 MW NTPC Green Energy award was described as Suzlon’s second large NTPC order, taking cumulative NTPC Green Energy orders to 1,544 MW ^[19]. Against a roughly 6.1 GW order book, that represents approximately 25.31%, but this is total NTPC exposure, not repeat-order exposure.
• The newly identified 378 MW repeat order alone represents approximately 6.20% of the current order book, derived from 378 MW divided by approximately 6,100 MW ^{[19] [20]}.
• Adding the separately disclosed 100 MW repeat GAIL order gives 478 MW of explicitly quantified recent repeat CPSE awards, or approximately 7.84% of the order book, derived ^{[21] [20]}. This remains an award-based proxy, not a reported residual order-book mix.

Bottom line: the NTPC order is below Suzlon’s recent quarterly intake scale, while the defensible disclosed figure for repeat CPSE exposure is at least about 6.20% for NTPC’s new repeat order alone, or about 7.84% including the recent GAIL repeat order. The broader 84% PSU/C&I figure should not be treated as the CPSE repeat-order percentage.
