The U.S. Department of Energy lists
Texas as the state having the most
installed capacity from wind turbines,
at 12,976 MW. Sparsely populated
West Texas is a natural spot for wind
machines. But wind, along with solar
systems, produces power intermittently,
and feeding it into the grid efficiently
presents operational problems. The state
also is seeing increasing investment not
only in utility-scale solar systems, but in
smaller rooftop systems. Oncor officials
believe batteries will provide an efficient
way of managing distributed loads and
storing energy until it is needed.
Other states are pursuing batteries as
well, and Navigant researchers believe
the market is on the threshold of growth.
“The grid-scale energy storage market
continues to develop in a piecemeal
fashion, but there are signals it is poised
for significant expansion in the com-
ing years,” wrote Anissa Dehamma, a
Navigant senior research associate. “In
particular, after several years of falter-
ing growth, lithium-ion batteries are
As Oncor pursues its plan in Texas,
state officials in California also are push-
ing utilities to embrace the technology.
In 2013, state power officials formalized
plans for California utilities to build 1,300
MW of storage capacity by 2020. South-
ern California Edison, one of the state’s
investor-owned utilities, recently an-
nounced it had signed contracts for 250
MW of storage, including batteries. ME

BATTERIES: FOR THE GRID
AN ORGANIZATION IS helping to improve the way Cambodian
schoolchildren learn about science and engineering.
The firm, Advancing Engineering Consultants of Dover, Del., guides infra- structure building projects in Africa and Southeast Asia. Now it shares ome of the basics of its work as hands-on lessons and a book for school
kids in Cambodia.
Reaching students at a young age and providing an introduction to engineering concepts is one of Advancing Engineering Consultants’ methods for local
capacity building, said Bryce Gaboury, the cofounder and managing director of
Capacity building is the efforts to train people on how to operate, maintain,
repair, and build machines to meet their basic needs.
The firm works with many different non-governmental organizations in Cambodia to expose children and students to various types of engineering careers
through hands-on workshops, he said.
“We go around and do several engineering workshops every year where we
present the book, then do some hands-on activities like building a bridge out of
straws, a small flashlight, etc.” Gaboury said. “The kids make things like hot air
balloons and structures that float in tubs of water.”
The book, “Buildings and Bridges,” illustrates the basics of engineering in full
color, with real-world examples, he said. The books are left with the kids after
the workshops, he said.
The firm also works with several canal rehabilitation projects in Cambodia
through the USAID Harvest Project.
“AE believes that engaging the local community in projects like this is integral
to the project success and the development of the community,” Gaboury said. ME
