Energy information duty


Duty to save energy

Does your company or institution (Environmental Management Establishment Act) use 50,000 kWh of electricity or 25,000 m³ of natural gas (equivalent) per year? Then, under the Environmental Management Activities Decree, you are obliged to take energy-saving measures with a payback period of 5 years or less.

This is the energy saving obligation. As of July 1, 2019, there is also an obligation to inform about energy saving. This means that you should have reported by 1 July 2019 for each Environmental Management Establishment Act which energy-saving measures you have implemented. You do that in the eLoket of RVO.nl. Not reported yet? Check whether you have an obligation to provide information and still report

These are all rules and therefore perhaps less exciting, but ultimately there is a lot to be gained for companies. Because money that you do not spend on energy just adds up to the profit.


Example on Bobst M5 650 mm

How does an installation work? The work takes place at the user’s workplace. First the old drying system is removed, including the control. The new system is then installed mechanically, the cables are pulled and the control system is connected. The printing press will be available for work again within a few days. Also inquire about the possibilities to immediately give the printing press a thorough overhaul.
