Running a full supermarket on 57 kW: smart control inside a capacity-constrained grid connection
Customer
Hoogvliet Supermarkten (Dutch supermarket chain).
The situation
Assets: Solar PV, a 215 kWh battery (Fox ESS), 10 EV charging points, a heat pump.
The store sits in a renovated historic building (a former auction hall, taken from energy label F to A+++++). Grid congestion capped the connection at just 57 kW β not enough to start the store conventionally, since essential systems couldn’t run simultaneously. The site also has a large PV array.
The challenge: get the most out of the existing connection without reinforcing it.
What was built
A combination of high-spec assets under central control, all balanced within the 57 kW limit: a 215 kWh battery, 10 charging points, a heat pump and the PV array, orchestrated by Tibo EMS. The Withthegrid Teleport provided the connectivity layer feeding live data into the system.
Technical realisation by Waterman Installatietechniek; battery supplied by Brenergie.
The result
The supermarket runs entirely within its 57 kW contracted capacity β opened without any grid reinforcement, with the connection used optimally and self-generated PV combined with storage and active control. Improved forecasting and a dynamic energy contract optimise consumption further. In the customer’s words: it runs smoothly and no shopper notices a thing.
"Grid congestion meant that, for the first time, we didn't have enough power to start up a store. We looked for a smart, efficient solution and chose Brenergie's EOS and Tibo's EMS β so we use our grid connection optimally and combine it intelligently with the energy from our large PV array."
