Industry overview & technical considerations
Utility storage may be co-located with generation, operated independently or used for network services. Define the point of connection, operating responsibility and actual service before comparing projects.
Record power, energy, nominal duration, technology and measurement boundary separately. Construction, first grid connection, full-capacity commissioning and commercial operation are different milestones.
Project coverage connects system design, power conversion, controls and operating evidence. Planned grid services or expected annual throughput should remain identified as expectations until supported by operating results.
