Together with Joulz, Dualtec has been working on STN2020, a new telecommunications network for energy supplier Stedin. After all, having a smart grid means that Stedin would need a modern and reliable telecommunication network. In this collaboration, we have been tasked with project managing the new telecommunication network. The project manager will determine whether new construction or modification is necessary, will take appropriate action and will monitor progress.
Wybe Jan Jorritsma, Telecom Chief at Stedin along with Auke Huisman, STN 2020 programme manager, explain this multiyear plan.
What does STN stand for?
Wybe Jan: ‘In addition to its electricity network, Stedin has a telecom network. This network consists of copper, fire and wireless connections that link all sites to the main operations centre in Rotterdam. It’s called STN, or Stedin Telecom Network.’
Wouldn’t it be easier to use existing telecom networks?
Wybe Jan: ‘Technically yes, but we don’t want that. Effective management of the electricity network is of crucial importance to our ability to guarantee supply. That’s why we want our data traffic to run across our own upgraded telecom network. Safety and security is paramount.’
Wybe Jan: ‘The transition in the energy industry, with more and more generators being added, is creating two-way traffic and a lot of dynamic. A smarter electricity network is necessary in order to manage this. That’s why many plants are being automated and made smarter. But even that is not enough. Increased data flows and automation demand modern telecommunication networks for the interconnection of everything. That’s what STN2020 is going to do.’
What do you have planned?
Auke: ‘The new network will create telecom connections between all the online systems in transmission stations, substations and the operations centre. Joulz will be updating and expanding this network. We’ll be migrating services that use telecom connections into a fibre network IP environment. The network will eventually link more than 300 sites that form Stedin’s most crucial junctions. This is a complicated operation at the very core of electricity transmission and distribution, and it will take several years to complete.’
