For years the Belgian procurement playbook was almost boring. Anchor with Cal forwards. Layer four quarterly clicks. Leave a thin spot tail. Repeat next year. That recipe worked because the underlying load looked roughly the same year after year. It does not look the same anymore.
Most industrial offtakers we audit have changed their load profile faster than their procurement strategy. Heat pumps replaced gas boilers in the technical room. A fleet manager added overnight EV chargers. A process line that used to run on steam is now electrified. Each of these decisions, individually rational, quietly invalidates the assumptions baked into the hedge sitting underneath them.
The old mix was a fair-weather portfolio
Cal forwards plus quarterly clicks plus a small spot residual was calibrated for a load whose intraday shape barely moved between calendar years. Volume drift was small enough to absorb. Peak hours sat in known windows. Spot exposure was a manageable tail, not a strategic decision.
That world is gone in Belgium. Electrified sites are no longer trending toward a slightly higher annual MWh number on the same shape. They are growing volumes while reshaping when those MWh are consumed, and the two effects compound. A heat pump pulls hardest on the coldest mornings, exactly the days when Belpex spreads widen most. EV depots push consumption into the evening shoulder where the curve is no longer the cheap window it used to be. Electrified process heat introduces a flexibility option, but only for operators who can see and price it.
Electrification moves both axes at once
The textbook hedge assumes you know two things with high confidence: your annual volume, and the rough hour-of-day mix of when you will consume it. Electrification undermines both at the same time. Year-on-year volume can step up by double-digit percentages in a single project. The intraday mix can shift further still. Multiply the two and a hedge that was correctly sized in January is materially mis-sized by Q3: overhedged in the off-peak hours that shrank, underhedged in the new peaks the heat pump created.
What is genuinely new is that the capacity tariff now amplifies this. Toegangsvermogen and the monthly peak charge turn a single bad quarter-hour into an annual cost. A site that electrifies without re-sizing its subscribed power and rethinking its peak-shaving logic is paying twice, once on the energy hedge that no longer fits and once on a network bill that has moved from background noise into a top-three cost line.
Procurement has to ride alongside the electrification plan
The honest fix is unglamorous. Hedge timing has to be coupled to the engineering plan that is changing the load. If a heat pump comes online in October, the click cadence for Q4 and the following calendar year has to be re-derived from the post-installation shape, not the historical one. If an EV depot is being commissioned in spring, the spot tail probably needs to grow before it shrinks, at least until the operating pattern stabilises and the new peaks are visible in metered data.
What this looks like in our dashboards
In the energy-management work we do with Belgian industrial sites, the practical shift is to model the hedge and the asset stack as a single decision, not two. Click strategies are scored against the forward curve and against the load shape the engineers are about to deliver, not the one that closed last December. Scenario comparisons (PV-only, PV plus battery, several BESS sizings) sit next to the capacity tariff bill, so the cost of a new peak is visible before it lands on an invoice. Hour-by-hour flexibility scores tell the operator which hours are worth shifting once the heat pump or charger is live, and which ones to leave alone.
The site that gets this right does not click more or click less. It clicks differently, against a load that finally matches the one it actually has.
Before signing the next Cal forward, ask your supplier or your in-house team to show you the load shape their hedge currently assumes. If that shape predates your last electrification project, the price you are locking in is already wrong. Model the next twelve months of consumption against your committed CapEx, then size the hedge against that, not against history.
