Germany, Regensburg: E.ON distribution system operators (DSOs) in Germany will put up to 180 new voltage-regulated distribution transformers (VRDTs) into service by the end of the year.
About 60 of the VRDTs are already operational. The nationwide rollout, which will encompass all of E.ON’s distribution systems in Germany, makes VRDT the first smart grid technology to achieve technological maturity. The technology was developed in a close partnership between E.ON and MR.
The VRDT technology developed by E.ON and MR sets new standards for the cost-effective integration of renewables. The German Energy Agency estimates that in Germany’s low-voltage networks alone VRDTs could reduce the cost of network expansion by roughly € 1.4 billion between now and 2030.
“This technology is a great example of how the Energiewende is promoting innovation.” said Ilse Aigner, Bavarian State Minister for Economic Affairs, Media, Energy, and Technology. “This high-tech transformer demonstrates that smart grids aren’t just a vision of the future but have already become reality. VRDTs will also reduce the burden on our citizens and communities by eliminating the need for additional electrical lines.”
“By rolling out VRDTs with MR technology, E.ON is the first DSO in Germany to deploy smart grid technology across all of its service territories.” said Dr. Thomas König, member of the E.ON Deutschland Board of Management.
In September 2012 MR became the first company in the world to present a technologically mature solution for VRDTs called GRIDCON® iTAP., which consists of an on-load tap-changer, a regulator, und a sensor for the low-voltage network. When combined with a transformer, the system yields a VRDT.
