We are now accustomed to charging stations refuelling our cars with energy, but what if the growing fleet of electric cars could also feed energy back into the grid when needed? So-called vehicle-to-grid technology could be a future solution that both contributes to a more stable electricity system…

As more sectors of society become electrified, the demand for technology capable of handling high voltage levels safely and precisely is increasing. Dr. Mohammad Kharezy works in high-voltage technology – a field that plays a key role in the transition to a fossil-free energy system. Through resear…

When it comes to preparing the electricity system for the future, Europe and Sweden are in a position where the technology is already developed and ready to be used. The big challenge will be the need for collaboration.

How do we secure energy supply in times of crisis? In Grums, Sweden, a battery storage system is now being tested to keep schools, preschools, and other vital public services running—even if the national power grid goes down. The project could become a key to a more resilient electricity system.

Thin glass wires are helping Hitachi Energy make production in Ludvika more data-driven, with the aim of sharpening its products. "Fibre optics can give us much more information than traditional sensors," says Christos Athanasopoulos, chief engineer at Hitachi Energy in Sweden.

Sweden produces a lot of electricity, but most of it is produced far from the majority of consumers and industry. The result? Failure to start new businesses due to energy shortages in many places, costing society large sums of money in lost revenue. – The site needs to think more proactively, but …

Region Skåne needed to know how electricity would be used in the future. With the help of electricity forecasts, the region now has a tool that can help develop both society and the economy.

Charging points are still not regulated in the same way as petrol and diesel pumps. As a result, the charging infrastructure is not subject to any inspection requirements, which could mean that hidden safety risks remain undetected and consumer protection is compromised. Independent verification ca…

Correct, accurate and traceable time is a prerequisite for our modern society and an important part of our total defense. Even so, we rely heavily on GPS signals to get accurate time — signals that can be easily disrupted.

There is great potential for district heating companies to strengthen their sector-coupling to the electricity grid by participating in ancillary service markets. In addition to profitability for the district heating companies, this contributes to a better and more stable electricity grid.

RISE works together with the Swedish transmission system operator Svenska Kraftnät to improve measurements in the transmission grid. Through accredited control, continuous monitoring and development of measurement methods, the grid's reliability is ensured.

Housing cooperatives, hotels and restaurant chains – these are just a few of the new charging station providers. RISE can help these many inexperienced organisations with regular function and safety inspections.

By using our electricity grids smarter, we can reduce the environmental impact and achieve more production of renewable electricity faster. The key is more flexibility, such as producing less electricity when it is windiest.

Minor deviations or quality deficiencies in products, services, processes or measuring instruments can cost enormous amounts in the form of money, reputation and lost business if not detected in time. RISE services can also create more business opportunities if you want to reach new markets. With u…
