Peak Shaving and Demand Charge Reduction
On most commercial and industrial tariffs, a few fifteen-minute intervals each month set a charge that applies to the whole month. Storage that discharges into those intervals attacks a billing line item directly, which makes the payback arithmetic simpler than a generation estimate.
What Goes Wrong At Each Stage And What We Do About It
- 1
Load analysis
The problem. Systems sized from connected load are either too small to clip the peaks or too large to pay back.
How we handle it. We size from twelve months of interval meter data where it exists, and from billing history where it does not, so the power and energy ratings are set against the actual demand curve.
- 2
System selection
The problem. The power rating and the energy rating pull in different directions - short sharp peaks need power, long plateaus need energy.
How we handle it. Cabinet and container formats are quoted across a range of power-to-energy ratios so the configuration matches the shape of the site's peaks.
- 3
Grid compliance
The problem. Connection approval stalls when the protection scheme and export behaviour are not documented.
How we handle it. Grid code and AC configuration are set for the destination market before production and documented for the connection application.
- 4
Installation
The problem. On-site integration of cells, converter and cooling is the longest item on the critical path.
How we handle it. Systems ship pre-integrated and factory-tested, so site work is foundation, cabling and commissioning.
- 5
Dispatch tuning
The problem. A storage system that discharges at the wrong time saves nothing.
How we handle it. We set the dispatch schedule against the tariff structure at commissioning and review it against the first billing cycles.
