Flex discipline. Standard supplier wrapper. One contract.
Multipurchase keeps the simplicity of a fixed-term supplier contract — but lets you flex how and when you buy energy inside the term. Periods, tranches, caps and triggers, all in one tidy product.

A fix with a difference
Multipurchase is what most businesses should have moved to years ago. You get a fixed term, but you don't fix the whole price on day one.
Pick your periods
Monthly, quarterly, seasonal (summer or winter) or annual. Choose the period structure that matches how your business actually consumes energy.
Up to four tranches per period
Each period can be split into up to four equally-sized tranches, traded as percentages of volume — and traded non-consecutively if you want.
Fix what matters, pass through the rest
Choose upfront which non-commodity components — FiT, RO, TNUoS — to fix into your unit rate and which to pass through. You decide where to take the risk.
Avoid the worst spike
Like full flex, we set a cap and a trigger on day one. If wholesale moves through, we secure the rest of your volume — protecting your budget without you watching the screen.
D-5 default trade
If you don't trade in a given window, we trade for you five working days before delivery. You never get pushed onto out-of-contract default rates.
PMS after every trade
Purchase Management Schedule sent after every trade — your weighted commodity price, what was bought, why, and what's next. No black boxes.
Period and tranche structures — two worked examples
You decide how flexible you want to be. Two of the more common structures:
The contract is divided into monthly periods. Each month is one tranche, traded as 100% of that month's volume. Good for businesses with a relatively steady load profile.
Summer and winter periods. Each split into two 50% tranches. You can lock part of the winter early without committing all of it, and time the rest with the market.
