Follower Cities Complete their Bold City Visions for Climate Neutrality

We are happy to announce that the Bold City Visions (BCVs) of the Follower Cities (FCs) are officially completed, and we are well on the way to achieving full political approval by each of the cities. Check out our recent news post to learn about the Bold City Vision framework and how it has been adapted to each city.

The Final Monitoring & Evaluation Phase of the Project

We are in the final Monitoring & Evaluation phase of the CityxChange project. This phase is where the lessons learned from the previous five years of the project come together to form the final report on challenges, lessons learned and recommendations from the Lighthouse and Follower Cities.

Project Timeline: 55/60 Months


Trondheim – +CxC energy trades go live at Brattøra

Trondheim – Green business development project – TK scaling and replicating +CxC energy solutions at Sluppen

Local Energy Markets make up a crucial part of the LHC Trondheim PEBs and help the city utilise approximately 20% of the available electricity that would otherwise go to waste. The live trades are now displayed in real-time on a large outdoor screen on the wall of the Brattøra PEB anchor building PowerHouse – the world’s northernmost energy positive building! You can also keep track of them through the website linked below.

Trondheim has set up and will facilitate a project on integrating a new, more sustainable stationary battery storage solution based on vanadium flow battery technology. The flow battery will be integrated within the PEB and the Sluppen Local Energy Market and is the result of successful collaborations between local SME Bryte Batteries, real-estate developer R Kjeldsberg and the Norwegian tech provider, Aneo. The project will last throughout Summer 2023 and demonstrates how new, green tech solutions can play an important role in the energy transition. Watch Norwegian broadcasting company NRK recent reportage and interviews with +CxC, for a glimse at the battery in action.

Between 7-10 February, the Alba Iulia team participated in the Kick off Meeting of the new Horizon Europe ASCEND project, in Lyon, France. The project “seeks to accelerate the implementation of positive, clean energy districts (PCED) for cities’ transition toward climate neutrality and social justice across Europe,” allowing Alba Iulia to continue building on the projects initiated during +CxC.

Pisek – Mobile app “Můj Písek” continues to support residents

Sestao – Sestao receives a grant to restore the Escuela de Aprendices


Písek continues to promote and update the “Můj Písek” mobile app! This mobile application is an interesting and practical helper for every citizen of Písek. The app shares important news from the office and its organizations, an overview of cultural, sports and social events, and updates about parking options and closurese. It’s a great way for citizens to stay connected.

Sestao has received a 3 million Euro grant from NextGenerationEU to renovate the Escuela de Aprendices. Having fallen into disrepair, the building is currently closed to the public.The hope is to connect the building to Sestao’s future PEB and transform it into a community space that can once again serve the citizens of Sestao.
