Eaton’s UPS-as-a-Reserve chosen for Swedish Power Grid pilot

STOCKHOLM, SWEDEN… Power management company Eaton has announced the first pilot project of its recently- launched UPS-as-a-Reserve (UPSaaR) solution. Svenska kraftnät, a Swedish electricity transmission system operator, has selected the Spring service by Fortum, a leading energy provider in the Nordic and Baltic countries, and Eaton’s UPSaaR to trial how the technologies help to balance Sweden’s power grid.

Eaton’s UPSaaR technology, which launched at the end of 2017, is the first of its kind for the data center industry and enables operators to earn from their investments in UPS, while helping energy providers balance sustainable energy demands. It enables data center operators to immediately respond to grid-level power demands to keep frequencies within allowed boundaries to avoid grid-wide power outages. This is a major step forward in delivering greener energy, as renewable energy is harder to predict and production can be more volatile – making it harder for energy providers to balance electricity supply.

Svenska kraftnät has selected the service for a pilot project researching the utilization of energy storage for demand flexibility. Starting in the first quarter of 2018, Fortum will offer 0.1 MW of UPS capacity to Svenska kraftnät’s frequency-controlled disturbance reserve. This reserve activates automatically and quickly if there is a drop in the electricity network’s frequency.

“Svenska kraftnät has recognized the benefits of Eaton’s UPS-as-a-Reserve solution in helping stabilize the power grid,” said Jussi Vihersalo, Business Development Manager, Eaton. “Sweden is at the forefront of renewable energy technologies and we’re convinced that it will be a model that other countries and organizations will emulate in the coming months and beyond. From an industry perspective, this news is the next step in enabling data center operators across the region to offer their capacity back to the grid.”

Eaton’s UPSaaR technology gives data center operators an opportunity to work with energy providers to momentarily reduce the power demands of the data center and even return power to the grid. A data center could expect to raise up to €50,000 per MW of power allocated to grid support per year.

Eaton is sponsoring the first DCD Energy Smart conference in Stockholm, on 13 March. This event will bring together the power and digital infrastructure industries. At the conference, Eaton and Fortum will present a keynote “Green Money in Grey Spaces” on how UPSs can act as virtual power plants and generate revenues for a data center.
