At the meeting of the Committee for Electrical Energy Systems (AEE) of the Association of German Transport Companies (VDV), GUW+ was the subject of two presentations. The first presentation introduced the general energy supply concept, the structure, and the ongoing operation of the demonstrator in Hannover-Döhren. The second presentation focused on the software solutions developed within the project for site selection, design, and intelligent functions of the battery storage system. Following the presentations, interested participants had the opportunity to take a guided tour of the GUW+ substation in Hannover-Döhren. |
Consortium Meeting, Dresden |
February 27-28, 2023 |
| The project partners met for a consortium meeting and workshop in Dresden at the end of February. Topics of the meeting included the current status of the different operation modes of GUW+, as well as the planning of the second cost-neutral project extension until the end of November 2023 with the aim of gaining further knowledge from the regular operation of the demonstrator. |
Consortium Meeting, Hannover |

GUW+ at the dcrps in Leipzig |
|
April 28 - 29, 2022 |
|
 |
The concept and construction of the GUW+ in Hanover was presented at the dcrps (international industry meeting for DC railroad power supply) in front of a professional audience of about 400 participants. The idea was well received and the GUW+ was also referred to in previous presentations.

Commissioning GUW+ Hanover Döhren |
|
April 2022 |
|
 |
The GUW+ has successfully completed the next step of commissioning. In addition to the light rail in the depot, it now also supplies the light rail on the line. In the same step, the HESOP components were also commissioned (left and center picture). Also encouraging: The e-bus charging tests show that the MuP charging technology works with the eCitaros (right picture).

Consortium meeting Hanover & Salzgitter |
|
July 12 - 13, 2021 |
|
|
|
After three virtual consortium meetings, the last meeting took place in July in Hanover and Salzgitter. On the first day, there was a site visit of the GUW+, which is still under construction at ÜSTRA in Hanover. For some project participants this was the first opportunity to visit the construction site. The pictures give an insight into the site visit:
The second part of the consortium meeting took place the next day at Alstom in Salzgitter. The associated partners had the opportunity to participate virtually. The current project progress was presented and the next steps were coordinated.

Construction progress of the substation GUW+ in Hanover Döhren |
December 1, 2021 |
|
|
|
The battery storage system was successfully integrated into the substation by the company MB Energy on behalf of Fraunhofer IVI. It consists of two strings of 14 used bus traction batteries, which were previously used in test fleets. The picture shows one of the strings including battery cooling and flue gas removal in the GUW+ Hanover Döhren.

The company building is now almost finished, last remaining works are in progress. The empty pipe route is also almost completed in the relevant area, the handover of the pipe clearances is still pending. The paving work around the building is the last step that will be visible from the outside. A lot has also happened inside: The company Elpro Berlin has already placed the racks in the building, including the HESOP of the company Alstom and also the charging technology of the company M&P. Things will get exciting in mid-August: the first charging mast for this line endpoint will be erected at night (manufactured by the company Masche Metallbau). |

The remaining work on the GUW+ building will be completed in the next few days. Inside, the raised floor has already been installed, transformer rails have been mounted in the transformer chambers, and the vinyl has been laid on the reinforced concrete floor in the battery rooms. The equipment with the ventilation technology is also well advanced. As shown in the photo, civil engineering work is still outstanding in the area of the parking lot. Among other things, the last meters of the empty pipe route must be laid to the GUW+. The company Elpro is also already on the construction site and will place the two transformers in the building in week 23. |

On March 26th, 2021, the shell of the over 300 m² company building was completed. More than 30 trucks delivered the precast concrete elements over the course of five nights, which were set up during the day. What follows now is work on the interior of the building, the roof and the facade, which is expected to be completed on May 17, 2021.

 |
At the Döhren depot in Hanover, construction work has begun on the first GUW+ at our implementation partner ÜSTRA. Completion of the building construction is scheduled for mid-May, after which the GUW+ plant technology will be installed. Commissioning and the start of trial operation are planned for fall 2021. |
Consortium meeting in DresdenDecember 3 - 4, 2019 |
