Synopsis: Konstelec Engineers Limited has emerged as the lowest (L1) bidder for three projects totalling approximately Rs. 165.85 crore, awarded by Numaligarh Refinery Limited and Advanced Weapons and Equipment India Limited under the Ministry of Defence, in a single-day announcement filed with NSE on May 22, 2026.
In a significant regulatory disclosure filed with the National Stock Exchange of India (NSE Symbol: KONSTELEC) on May 22, 2026, Mumbai-based Konstelec Engineers Limited announced that it has received L1 (lowest bidder) confirmation for three separate projects across two marquee clients Numaligarh Refinery Limited (NRL) and Advanced Weapons and Equipment India Limited, a body under the Ministry of Defence, Government of India. Execution activities across all three projects are expected to commence shortly, pending formal issuance of Letters of Award (LOA) and completion of contractual formalities.
The first two orders relate to Instrumentation Works for EPCM-2 Services for the RPTU Unit at Numaligarh Refinery. Under Tender ID 2025_NRL_891216_1 (Group A), the estimated order value is Rs. 59.53 crore (exclusive of GST), while under Tender ID 2025_NRL_891216_2 (Group B), the estimated order value is Rs. 32.01 crore.
Together, the two NRL instrumentation packages add up to Rs. 91.54 crore, a significant chunk of business from one of India’s most strategically important refineries located in Assam, which is in the midst of a large-scale capacity expansion.
The third order, and arguably the most headline-grabbing, comes from Advanced Weapons and Equipment India Limited (AWEIL) under the Ministry of Defence. The project involves the Augmentation of FGK Internal Electrical Power Distribution System on a turnkey basis, with an estimated order value of Rs. 74.31 crore (inclusive of GST).
A defence order of this nature carries not just financial significance but also reputational weight placing Konstelec in an elite list of engineering firms trusted to execute mission-critical electrical infrastructure for India’s armed forces ecosystem.
The combined estimated value of these three L1 confirmations stands at approximately Rs. 165.85 crore, which represents a material addition to Konstelec’s order pipeline. For a consulting engineering and EPC services company of Konstelec’s profile, landing all three bids simultaneously is a strong signal of competitive tendering capability and technical credibility across diverse sectors.
As of May 22, 2026, Konstelec Engineers Limited maintains a robust order book of nearly Rs. 650 crore, reflecting a sharp expansion in its execution pipeline following multiple high-value contract wins across FY26. The latest Rs. 165.85 crore addition from Numaligarh Refinery Limited and Advanced Weapons and Equipment India Limited further strengthens revenue visibility for the next 24 – 36 months. The company’s order book remains diversified across hydrocarbons, power, ports, and defence infrastructure, while management continues focusing on high-margin instrumentation and process automation services.
The NRL orders are particularly notable given the scale of Numaligarh Refinery’s ongoing expansion. NRL in which Oil India Limited, Government of Assam, and Bharat Petroleum hold stakes is executing one of the largest refinery expansion projects in Northeast India, targeting a tripling of capacity.
Instrumentation and controls work of this nature, classified under EPCM-2 services, involves design, procurement, and construction management of process instrumentation systems, a highly specialised domain where few firms have the requisite track record.
The AWEIL defence order underscores Konstelec’s growing relevance in India’s defence infrastructure space. With the government pushing for greater indigenisation and modernisation of defence facilities under the Make in India initiative, EPC firms with proven electrical and instrumentation expertise are increasingly being considered for facility augmentation projects.
Winning such a bid on the Government e-Marketplace (GEM) platform further demonstrates the company’s compliance with government procurement norms and its competitiveness on price.
Shares of Konstelec Engineers Limited surged nearly 5% on Friday to hit the upper circuit at Rs. 39.10 after the company announced multiple project wins worth Rs. 165.85 crore from Numaligarh Refinery Limited and Advanced Weapons and Equipment India Limited under the Ministry of Defence.
The stock touched its 5% upper band during intraday trade, with strong buying interest visible and no sellers available at the time of reporting. Investors are closely tracking the company’s growing Rs. 650 crore order book and expanding presence across refinery, infrastructure, and defence projects.
