Onde wins contracts to build 120 MW of Polish solar

• Onde will build 120 MW of PV plants in Poland for Estonian renewables producer Sunly, extending a cross-border partnership amid strong market momentum.

Polish renewables contractor Onde SA has signed two new EPC contracts with Estonia’s Sunly SA to deliver an additional 120 MW of photovoltaic capacity across Poland. The deals deepen a cross-border partnership that has become a fixture of Poland’s solar buildout, pairing a local heavyweight in design-and-build with a developer expanding its Central European footprint.

While site specifics weren’t disclosed, the portfolio is expected to follow a familiar, bankable template: high-efficiency modules—often bifacial—on single-axis trackers where terrain allows, or optimized fixed-tilt on compact plots; DC/AC ratios sized for robust annual yield rather than headline peaks; and plant controllers capable of reactive power support, low/high-voltage ride-through, and rapid curtailment in line with Polish grid codes. Unified SCADA across the projects should sharpen O&M—string-level telemetry, thermal inspections, and predictive analytics to catch underperforming blocks early.

Poland remains one of Europe’s liveliest PV markets, driven by competitive auctions, corporate PPAs, and merchant opportunities as industry decarbonizes. That growth has stressed interconnections in some regions, making standardized execution and early reservations of long-lead electrical gear—transformers, switchgear, protection systems—critical to schedule certainty. Portfolio EPCs like this one help: bulk procurement lowers costs and reduces the risk that one delayed component stalls the entire program.

Community and environmental considerations are now table stakes. Expect biodiversity measures that convert arable fields into species-rich grassland beneath arrays, reinforced hedgerows, construction-phase traffic management, and storm-water controls sized for intense rainfall. Decommissioning bonds and clear restoration plans have become standard features of municipal approvals, reassuring landowners and councils alike.

Commercially, Sunly can mix offtake routes from corporate buyers to utility contracts, with measured merchant exposure where node fundamentals support it. Storage isn’t part of the day-one scope, but designs typically preserve pad space and transformer headroom for a future two-to-four-hour battery—shifting midday output into the evening ramp and opening ancillary-service revenues as Poland’s flexibility markets mature.

Taken together, the twin orders are less about a single headline number and more about cadence: repeatable engineering, disciplined interconnection, and fleet-level O&M that turns a pipeline into electrons on the wire—on time, on spec, and ready for the next tranche.
