RES Americas / Nordex
Who is RES Americas?
 Colorado Based
 Engineering, Procurement &
Construction
 Constructed 10% of USA Wind
(> 6000MW)

250MW in Colorado (Xcel)
 Constructed > 100MW of PV
Solar
 Now constructing:

The Biggest Battery in the
Province of Ontario (4/2014)

The 2nd Biggest Battery in
the State of Ohio (2/2014)
Where Did RES Come From? – McAlpine Construction
 RES Group / RES
Americas spawned
from 150 years of
McAlpine Engineering
& Construction
experience.
 Nuclear power plants,
oil refineries, port
facilities, the 2012
Olympic Stadium and
more..


New ES technologies show great promise (RES is presently involved in 2
CAES projects and one Thermal ES project), but are mostly not available
today, except as demonstration projects.

Because of the huge investment in Electric Vehicle batteries, lithium based
grid energy storage systems are available and reliable.
How can Energy Storage Help CREA Members?
 Distribution Deferral

Providing local power to defer the construction of transformers,
substations, and new distribution lines.

Cost effectively handle incremental load growth

Same equipment can provide islanding / UPS capabilities
 Providing 3rd Party Ancillary Services

CREA members are being charged for Ancillary services (regulation,
spinning reserve, etc.) in Schedule 3, 5, and 6 of TriState and WAPA
tariffs. These services can be provided through energy storage.

Members can avoid these charges through 3rd party supply.

FERC ruling 784 (a FERC Energy Storage order July 2013) makes this
easier and more cost effective.

3rd Party Ancillary Services
 FERC 784 (July 18th, 2013)

“Third-Party Provision of
Ancillary Services; Accounting
and Financial Reporting for New
Electric Storage Technologies”

Schedule 3, 5, and 6 of
Transmission provider tariffs.
These services can be provided
through energy storage, often at
less cost.

TriState could own or contract
these services less expensively,
and pass on savings to
members.
Final Words on Energy Storage
 Energy Storage can serve
several functions at once.
 Several new low cost
Energy Storage options
should be available as
utility products within 5-7
years.
 RES can provide technical
and financial analysis of
any potential distribution
deferral project.
