Solar EPC Balance of System: Lessons From the ₹741 Crore Fatehgarh Order

ArMee Infotech has secured two Letters of Award from Bondada Engineering worth a combined ₹740.97 crore for amended solar EPC balance of system packages at a 600 MW solar project in Fatehgarh, Rajasthan. The work splits into two 300 MW blocks, Block 1 valued at ₹375.18 crore and Block 3 at ₹365.79 crore. [Source]

The scope covers engineering, procurement, manufacturing, supply, erection, installation, testing and commissioning of BOS works, along with associated power evacuation infrastructure. It also includes three years of operations and maintenance and annual maintenance for designated plant equipment. [Source]

Why This Order Is Bigger Than a Module Story

What makes this order worth examining isn’t the headline number, it’s what the scope actually covers. This is a solar EPC balance of system award, not a module-supply contract, and that distinction matters because a 600 MW plant becomes commercially useful only once its civil, electrical, control, protection, testing and evacuation systems are ready to export dependable power. Module installation is the visible part of any solar EPC balance of system project; the harder work sits underneath it, in the DC cabling, inverter stations, AC collection systems, transformers, switchgear, SCADA integration, pooling-substation work, and the transmission line that ultimately carries power to the grid.

Evacuation Infrastructure Is the Real Timeline Risk

The Fatehgarh order bundles its solar EPC balance of system scope directly with solar power evacuation infrastructure, and that pairing reflects a growing industry reality. Renewable generation capacity can often be built in 18 to 24 months, but transmission infrastructure frequently takes three to four years from planning through commissioning. [Source] 

When transmission planning trails generation development, a plant can sit physically complete while still unable to export a single unit.

That timing mismatch is becoming a bigger industry concern. Reports indicate roughly 248 GW of renewable, storage and hydro connectivity is scheduled to come online between August 2026 and 2031, including 53.4 GW in 2026 alone and nearly 80 GW in 2027. [Source]

That volume puts real pressure on coordinated construction-to-grid planning across the industry, making the solar EPC project timeline for evacuation work just as critical as the timeline for modules and structures.

Why the Three-Year O&M Scope Matters

After commissioning, ArMee is also responsible for three years of operation and maintenance (O&M) and annual maintenance. This means that the contractor stays connected to the plant for a long time after handover. Solar EPC O&M work like this typically covers availability guarantees, fault response, spare-parts strategy for inverters and protection panels, and performance-ratio tracking, work that determines whether a 600 MW asset actually performs as designed once it’s exporting power.

The Bigger Lesson for Developers

Orders structured this way point to a broader shift in how solar EPC balance of system scope gets evaluated within contractor selection. A contractor shouldn’t be judged only on installed MW or module procurement; developers increasingly need to know whether the same solar EPC contractor controls BOS, evacuation, grid interfaces, and commissioning as one integrated system, rather than as separate handoffs prone to gaps at every interface. When solar EPC balance of system works and evacuation infrastructure sit under a single contract, as they do at Fatehgarh, the project has one accountable party for the systems that actually decide whether a plant can export power on schedule.

For an industry increasingly constrained by grid readiness rather than generation capacity, the meaningful progress metric for any solar EPC balance of system project isn’t installed MW. It’s grid-ready MW, capacity backed by completed BOS, approved protection, working SCADA and metering, and an energised evacuation route capable of actually delivering power.
