Raslag appoints owner’s engineer for 100-MW Philippine solar-storage project

• Raslag chose Greencity Energy Philippines as owner’s engineer for a 100-MW solar project with proposed battery storage, overseeing design, procurement, and grid compliance.

Raslag Corp has tapped Greencity Energy Philippines Inc as owner’s engineer for a planned 100-MW solar project that includes a proposed battery energy storage system (BESS), marking a key step from concept to bankable delivery. The appointment gives the developer a single technical fiduciary to defend performance, schedule, and safety as the project moves through design, procurement, construction, and commissioning.

What does an owner’s engineer actually do here? First, Greencity will run a deep design review—validating site layout, resource modeling, shading and soiling assumptions, and DC/AC sizing to maximize annual yield rather than just peak output. Expect scrutiny of module and inverter selections (including grid-forming capabilities), tracker foundations for local soil conditions, and the BESS architecture—duration, thermal management, fire safety, and sectionalized isolation—so the plant can shift midday generation into evening peaks and provide fast frequency response.

Second, the firm will support competitive EPC and equipment tenders. Standardized bid books, clear performance guarantees, and warranty terms for both PV and storage should compress costs and reduce ambiguity. On schedule-critical items—transformers, switchgear, and protection gear—Greencity will push early reservations and approve factory acceptance tests to avoid late-stage surprises.

Third, grid integration. The Philippines’ networks are increasingly shaped by variable renewables, so the project’s plant controller must deliver reactive power, fault ride-through, and rapid curtailment response in line with interconnection requirements. Studies on harmonic distortion, voltage step changes, and protection coordination will be table stakes, with staged energization to bring blocks online safely.

During construction, the owner’s engineer implements QA/QC—weld inspections, torque checks, grounding continuity, cable routing audits—and enforces environmental and community measures: traffic plans, erosion control, storm-water management, and biodiversity buffers. For the BESS yard, emergency response planning with local fire services, gas detection, and remote thermal monitoring will be central to approvals and insurance.

Finally, at commissioning, Greencity will witness performance tests, validate reliability runs, and confirm SCADA telemetry and cybersecurity hardening before recommending commercial operation. Post-COD, they’ll help tune tracker algorithms, cleaning cycles, and battery dispatch strategies to protect capacity factor and revenue.

Why it matters: a disciplined owner’s engineer increases lender confidence, shortens problem-solving cycles, and future-proofs the interconnection for storage expansion as evening peaks intensify. If executed well, Raslag’s project will deliver reliable daytime power, firmed evening supply, and a flexible resource that supports grid stability—while setting a template for repeatable solar-plus-storage builds across the archipelago.
