But that’s changing. Several countries in the European Union, including Spain, Sweden, Portugal and Poland, have embarked on a new project called UPGRID to bring the medium- and low-voltage sections of the grid, which utilities use to send around electricity to homes and businesses, into the 21st century. Funded by $12.6 million in grants from the European Union, the utilities involved have started adding sensors to the wires and power equipment. The sensors will feed data to software for analyses that will help personnel in the control room as well as in the field get a better picture of where, when and how much electricity is being used.
The idea is that UPGRID will serve as a test case for developing standards for a truly smart, pan-European grid. In northern Spain around the city of Bilbao, for example, the utility Iberdrola Distribución Eléctrica has installed monitoring sensors on substations, transformers and power serving some 350,000 consumers. The technology will offer new insights into what is happening on the network. “We will be able to predict where an outage is on the grid faster, and know why power is out,” says Ana Gonzalez, control systems manager at Iberdrola.
Thanks to UPGRID, Iberdrola field engineers also now have a new app on their mobile devices that gives them a real-time picture of the grid, something that previously was only available in the utility control room. The app is a version of GE’s Advanced Distribution Management System (ADMS) software, which utility control rooms use to monitor and control activity on their distribution grids. “If a technician needs to cut a low-voltage line to make a repair, they can process it and get approvals right from a mobile device in the field,” says Miguel Ballesteros, program manager for Grid Solutions at GE Energy Connections.
At the demonstration project in Sweden, GE engineers are working with the Vattenfall utility to install sensors in substations and on power lines in the rural residential area of Åmål, a lake town near the southern border with Norway. The goal is to learn more about residential power needs. A similar project in Poland is monitoring data from power lines serving the industrial part of the port of Gdynia, while in Portugal, researchers are using sensors to see exactly how electricity is used inside homes.
UPGRID also should help provide more clarity as the grid grows increasingly complex thanks to intermittent sources of renewable power like wind and solar, which make it harder for utilities to maintain the grid’s delicate balance of supply and demand.
This benefits consumers because they will be able to make informed choices about energy use — e.g., programming appliances to operate during times when electricity is cheaper. On the business side, factories will be able to better schedule the use of equipment to take advantage of fluctuating pricing.
All this could boost the profits of utilities by as much as 30 percent, according to a McKinsey report, which says “massive opportunities await those able to transform themselves ahead of the curve” by creating a smart grid.
The UPGRID project will run through the end of 2017.
UPGRID has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No 646.531.
