Utility Grade Products Available Today

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.

Distribution Deferral

Energy Storage

Energy Storage

Energy Storage

Transmission Transformer or HV line overloading?

Inject energy storage power as required downstream of HV

transformer

Distribution transformer or 69kV

line overloading? Inject energy storage

power as required downstream on low side of substation.

Voltage support needed at end of distribution line?

Inject energy storage at load end instead of more distribution

lines.

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. Questions?
