Econergy energises Apple-backed 52-MW Polish solar farm, Resko now operational

• Econergy has connected the 52-MW Resko solar farm to Poland’s grid, an Apple-backed project that adds clean daytime capacity and supports corporate decarbonisation.

Econergy has brought the 52-MW Resko solar farm online in Poland, adding a meaningful block of daytime generation to a system still leaning on coal and gas. The project is backed by Apple as an offtaker, illustrating how corporate demand continues to unlock financing and accelerate delivery of new renewable capacity in Central and Eastern Europe.

On the engineering side, Resko follows the modern utility-scale playbook: high-efficiency (often bifacial) modules on single-axis trackers to extend production into shoulder hours; inverters and plant-level controls tuned to Polish grid-code requirements for reactive power, ramp-rate limitations, and ride-through during faults; and unified SCADA with string-level telemetry that enables predictive maintenance—thermal imaging, IV-curve tracing, and data-driven cleaning routines.

Corporate offtake changes the commercial calculus. Long-dated contracts from investment-grade buyers reduce merchant risk and help sponsors secure better debt terms, which in turn feed back into competitive power prices. For Apple, the deal feeds an expanding portfolio of clean-energy purchases that support its supplier and operations decarbonisation goals, while creating new, additional capacity in a market that needs it.

Siting and delivery details matter in Poland’s grid. Building near strong nodes limits curtailment risk and interconnection delays; standardized substation blocks and early reservations for transformers and MV switchgear help avoid the supply-chain bottlenecks that have slowed some peers. Environmental measures—traffic and noise controls during construction, biodiversity-friendly groundcover beneath arrays, and decommissioning and recycling plans—are now standard in permits and lender requirements.

Looking ahead, designs like Resko’s often preserve pad space and transformer headroom for future batteries. A two-to-four-hour system would let Econergy shift energy into the evening peak and participate in ancillary services as market products evolve, improving capture rates and resilience.

For now, the headline is straightforward but significant: a 52-MW solar plant is producing, a marquee corporate is buying, and Poland’s grid gets cleaner, more predictable daytime megawatt-hours.
