Austrian Power Grid (APG) is Austria’s independent power grid operator, with control and responsibility for transporting electricity across regions at maximum voltage. As it ensures the country is supplied with electricity, the APG infrastructure is a lifeline for the Austrian population and for businesses. The mains network, which is approximately 3,400 km long in total, is operated, maintained and continuously modified to suit the growing demands of society and the economy by a team of around 600 specialists. Overall, APG will invest 3.5 billion euros in network expansion and modification by 2032 in order to meet current and future requirements for a secure electricity supply, the energy revolution and increasing electrification of all aspects of modern life – whether it’s streaming, e-mobility or hydroelectric steel production.
The framework contract has been agreed for five years, with the option for an additional three years, and covers the installation of ~80 AC and ~130 DC charging stations connected to the auxiliary installations and the associated data integration. This requirement is the result of APG’s planned transition to e-mobility for its fleet of company vehicles.
At least two separate DC charging points with between 30 and 120 kW output and two separate charging points with up to 22 kW output will be installed at around 50 APG sites across Austria, and they will be supplied by both the emergency busbar and by the auxiliary busbar. The specific conditions at the substations need to be met, which include preventing negative impacts such as excess voltage and conducted feedback on the auxiliary installations and ensuring electromagnetic compatibility (EMC).
The AC and DC measurements and integration of the data into existing and new systems also form part of the contract, along with full wiring, MCC slide-in modules, adaptation of the existing outputs and all construction work to enable installation and integration of the charging points (foundations, cable runs, ducts etc.).
The first stage is to re-equip the network hubs, i.e. APG’s largest, staffed substations, and the substation in Obersielach will be the first site to be modified.
After successfully installing the PV system at the APG control technology site in Kronstorf, we are delighted to have won another contract for APG and to work alongside them on a new project promoting sustainable energy.
