The northern Dutch town of Heemstede is nestled among vast dunes near the North Sea. The region is known for its flower industry. The large tulip fields between the canals and meadows of the polder landscape are a beautiful sight. This is where the Nijssen Tuin & Bulbs company has set down roots. The flower wholesaler sells flowers in its own garden centre, packs them for wholesale in nearby Amsterdam and also exports the flowers and bulbs all over the world via its own online shop.
Nijssen Tuin & Bulbs, as a flower wholesaler, requires a large amount of power. The plants require lighting and watering and, depending on the season, heating or cooling. The flower bulbs must be kept below 5°C at all times to prevent them from sprouting prematurely. And, of course, the packaging machines also need electricity. In addition, the owner’s own house is located on the company premises; he lives there with his family and, of course, also consumes electricity.
The company’s energy demand peaks during the important main season between the beginning of June and the end of September, when the flower bulbs are harvested, washed, dried and then cooled. Covering these needs with the conventional power supply has become more and more of a challenge as business activity has increased, especially now that grid capacity in the Netherlands is under severe strain due to the energy transformation. According to a forecast by the local energy supplier, it could take up to 10 years before the supplier would be able to offer a supply that meets local demand.
Another challenge: business trends are difficult to predict since they depend heavily on developments in international markets. This means that demand for energy can remain constant or increase sharply. What is needed is a flexible energy supply solution that can cover peak loads and, if necessary, grow along with business.
Expirion, a local installation company and long-standing TESVOLT partner, rose to the challenge. It installed a photovoltaic installation with 276 modules and 100 kWp on the roofs of the garden centre. The team also upgraded the installation to include a battery storage system that can be expanded to meet the energy demands of the flower wholesaler. Since they had to install the storage system outside for fire safety reasons, Expirion opted for TESVOLT’s container storage system TPS HV 80 E.
The TESVOLT storage system TPS HV 80 E has been hidden behind the large hall of the garden centre for several months. Some advantages have already paid off for Nijssen Tuin & Bulbs.
Installation
Plug and play: the TPS HV 80 E is pre-configured and pre-installed in the container production facility in Lutherstadt Wittenberg. This meant the installation could be completed quickly.
Peak shaving
The storage system is able to reliably absorb the peak loads that occur mainly at the beginning of the harvest season in June, so power can be supplied with a corresponding reduction in connected load.
Expandability
The TPS HV 80 E is completely modular and can be easily expanded as operations and energy demands grow.
Energy trading
The storage system runs on-grid, meaning it is connected to the power grid. Since there is a surplus of wind power in the Dutch power grid, there is the option to generate additional income in the future by storing electricity and feeding it into the grid when it is needed.
SMA, TESVOLT, Expirion: this is the dream team!

The solar installation and the energy storage system work perfectly – we are very happy with them!
