CHICAGO -- April 16, 2014

GE’s Digital Energy business (NYSE:GE) today announced it will provide series
compensation capabilities to three of SP Power Systems Limited’s (Scottish
Power) facilities in southern Scotland, helping the utility meet and mitigate
today’s highly complex and technical grid challenges. GE’s series compensation
technology is being showcased this week at the 2014 IEEE PES Transmission &
Distribution Conference & Exposition in Chicago.

The utility will be installing series capacitor banks with sub-synchronous
resonance (SSR) filters to its substations, increasing the reliability,
efficiency and power transfer capabilities of Scottish Power’s 400-kilovolt
transmission network. The updates to Scottish Power’s network will continue to
allow power to flow seamlessly from northern Scotland into England. GE’s
series compensation solution enables the broader initiative of the European
Union’s target to integrate more than 15 percent renewable generation into
their portfolio mix.

GE and Balfour Beatty Engineering Services (BBES)—a leading supplier for
Scottish Power’s substation equipment—will provide installation, commissioning
and maintenance of series compensation banks with SSR filters at Scottish
Power’s Moffat (400-kilovolt, 560-MVAr), Gretna (400-kilovolt, 560-MVAr) and
Eccles 1 and 2 (400-kilovolt, 442-MVAr each) substations. These series
capacitor banks with SSR filters will provide Scottish Power, part of the
Iberdrola Group, a cost-effective method to increase power transfer across its
long transmission lines. Working with BBES enabled GE to fulfill and meet
local requirements and standards for Scottish Power’s facilities. It also
establishes a localized presence in the region that can provide long-term
support and maintenance to each of the series capacitor banks as needed.

“Our priority is to provide a safe, reliable and efficient transmission
network to benefit all of our customers,” said Mike Young, series compensation
program manager, Scottish Power. ”We believe that GE offers the best technical
solution and meets the stringent safety and environmental requirements of our
project. We look forward to working closely with the GE team to deliver this

The four series compensation banks installed by GE will utilize its reliable
fuseless capacitor design and will include metal-oxide varistors and triggered
air gaps. The scope of the project also includes detailed studies and analysis
from GE’s Energy Consulting business for the design and application of the SSR
filters. The project is scheduled to be completed in 2015.

“Understanding Scottish Power’s needs for an efficient and safe transmission
network, our world-renowned Energy Consulting team provided detailed system
studies and analysis on SSR mitigation and filter design, equipping Scottish
Power with the most economical and reliable approach to meet their
requirements,” said Bob Turko, general manager, power systems, GE’s Digital
Energy business. “This project reinforces our industry-leading series
compensation system utilizing SSR mitigation filters, demonstrating GE’s
strong technical capability and reestablishing its focus in the European

This announcement builds on GE’s deep history as a supplier of SSR mitigation
solutions and filters, which dates back to the 1970s—from the Navajo station
40 years ago to the company’s most recent project with Newmont Mining.
