Edify Cleared for 100-MW Solar-Battery in NSW
- Edify’s 100‑MW solar‑plus‑storage clears permits in NSW, targeting evening peaks and grid stability as coal exits—now racing through interconnection, EPC, and financing to deliver firmed renewables.
Edify Energy won permitting approval to build a 100‑MW solar-plus-storage project in New South Wales, clearing a key hurdle in a grid where access and regulatory certainty can rival hardware in importance. The hybrid plant will pair daytime solar generation with a co-located battery to shift output into evening peaks and deliver fast-response services that stabilize frequency and voltage as coal units retire.
Expect a modern, grid-friendly configuration and controls tuned to AEMO requirements. Next: interconnection studies, EPC contracting, financing, and long‑lead procurement, with commissioning tests the make‑or‑break. Hitting timelines would add meaningful firmed renewables to NSW’s evolving supply stack.
What makes Edify’s NSW solar-plus-storage plant a grid-friendly, AEMO-aligned asset?
- Co-located battery sized and controlled to shift solar into evening peaks while reserving headroom for FCAS, enabling co-optimized energy and ancillary service revenue in AEMO’s 5‑minute market.
- Grid-forming inverter capability (or grid-following with advanced virtual inertia modes) to provide system strength, fast voltage control, and fault current support in weak parts of the NSW network.
- Compliance with Generator Performance Standards negotiated via detailed PSCAD/PSSE models, including low/high voltage ride-through, frequency ride-through, and dynamic reactive power obligations.
- Primary Frequency Response enabled by default with appropriate droop and deadband settings to meet AEMO’s mandatory PFR rule and reduce causer‑pays factors.
- Participation in Fast and Very Fast FCAS (including sub‑2s) with millisecond-level battery response to help arrest frequency deviations as thermal units retire.
- Hybrid plant controller with AGC integration, ramp-rate limiting, and constraint‑aware dispatch to follow AEMO setpoints precisely and minimize intervention or constraint violations.
- Dynamic reactive support via inverter VAR control and potential STATCOM-equivalent performance to hold local voltages within limits and support Transgrid’s system strength needs.
- Headroom and curtailment strategies built into bids to ensure consistent FCAS availability rather than chasing marginal energy, aligning with AEMO co‑optimization and reliability objectives.
- “Do No Harm” approach to system strength and harmonics, including tuned filters, EMT‑validated settings, and, if required, system strength remediation agreements.
- Robust hold‑point and commissioning test plan (R1/R2, GPS verification, model validation) to reach full registration without extended constraints or AEMO-imposed caps.
- High‑fidelity self‑forecasting for semi‑scheduled dispatch, reducing uncertainty in NEMDE and improving dispatch conformance and settlement outcomes.
- Cyber‑secure, redundant SCADA/telemetry meeting AEMO data refresh and visibility requirements, enabling real‑time status, contingency response, and event playback.
- Islanding and black‑start supportive controls (where contracted) to assist restoration and improve resilience, consistent with emerging NEM restoration strategies.
- Curtailment-aware operations that respect network thermal and stability limits (N‑1), reducing congestion impacts and aligning with constraint equations in NSW REZ corridors.
