In a world where the energy transition is becoming crucial, the city of Örebro in Sweden has undertaken a bold project: to transform the way energy is produced, shared and consumed in an entire neighborhood.

Tamarinden, a veritable laboratory of innovation, has become a benchmark for cities seeking to reconcile urban growth and sustainability.

Jan Johansson, project manager for energy and sustainable construction at the municipality of Örebro, had the opportunity to take part in the Tamarinden adventure, an innovative project that has transformed the way we think about urban energy. The Tamarinden project was born of the city of Örebro’s desire to grow while reducing energy consumption and greenhouse gas emissions.

The project, developed using Dualsun photovoltaic solar panels, was made possible by close collaboration with the Dualsun Nordics team. It relies on collective self-consumption, with around 605 Dualsun FLASH 425 panels installed in 8 apartment blocks.

From the outset, Tamarinden was conceived as a forward-looking district, incorporating state-of-the-art energy solutions, including Dualsun photovoltaic solar panels. These installations not only generate local electricity, but are integrated into a wider system of building-to-building energy sharing, energy storage and grid support services, as well as a fleet of electric car-sharing vehicles.

The whole project aimed to demonstrate that collective energy management, supported by advanced solar technologies, was not only feasible, but also beneficial on a large scale.

However, the legislative framework at the time didn’t allow electricity to be shared between different buildings, forcing the team to rethink the existing rules. They took risks, convinced that to innovate, it was sometimes necessary to bypass regulatory obstacles. In 2022, after several years of effort, a legislative breakthrough finally legalized this type of energy sharing.

Today, Tamarinden is not just a forward-looking district; it represents a model, a true pioneer in the construction of smarter, more energy-efficient cities. The project has proved that it is possible to reduce peak energy demand, maximize the use of local renewable energies and build a system where sustainability goes hand in hand with economic profitability.

The partnership with Dualsun Nordics and the support of RISE have played a crucial role throughout this adventure. Hundreds of Dualsun photovoltaic panels have made it possible to deploy substantial solar power plants that not only provide local energy production, but also a sustainable management system for the entire neighborhood. Together, they have created an eco-responsible neighborhood and laid the foundations for Örebro to become an energy-intelligent city.

This project demonstrates that change is not only possible, it’s happening. Today, many cities and companies are looking to Tamarinden and the technologies it deploys for inspiration. Jan Johansson is proud to see that their work has paved the way for a cleaner, more efficient and better-connected energy future!
