Half-Hourly (HH) Business Electricity
Specialist procurement for half-hourly metered sites — including load profiling, capacity optimisation and pass-through vs fixed contract advice.
Who this is for
Sites with peak demand above 100 kW, or any I&C site with a half-hourly meter already installed.
How it works
- We pull your HH consumption data and build a load profile.
- We model fixed, flexible and pass-through options against your usage curve.
- We negotiate capacity levels and DUoS band exposure.
- We manage tender, acceptance and switch across the panel.
Benefits
- Tariffs matched to your actual load profile
- Agreed capacity right-sized (avoiding excess capacity penalties)
- Peak-avoidance strategies for winter DUoS red-band exposure
- Detailed cost breakdown by wholesale, network and non-commodity components
Why HH tariffs are quoted differently
Unlike a headline p/kWh, an HH contract typically separates commodity (wholesale energy), transportation (DUoS/TNUoS), balancing (BSUoS) and non-commodity costs. Comparing offers requires normalising all four — a simple 'unit rate' comparison is misleading.
Capacity charges
You pay every month for the agreed capacity you have booked, regardless of use. Right-sizing capacity to actual peak demand — often by only 10-20% — can save more per year than switching supplier.
Fixed vs flexible
Fixed HH contracts give certainty; flexible/basket-purchase contracts let very large users buy in tranches against the wholesale market. Flexible needs energy-management capacity in-house or via a bureau — we help you decide which is realistic for your team.
