Xtreme Power’s dynamic<br />
power resources after<br />
installion <strong>at</strong> the<br />
<strong>Koloa</strong> Subst<strong>at</strong>ion.<br />
10 KIUC CURRENTS<br />

B<strong>at</strong>tery Storage System <strong>Up</strong> <strong>and</strong> <strong>Running</strong><br />
KIUC signed a contract on January 10, 2011, with Xtreme Power Inc.<br />
to purchase a 1.5megaw<strong>at</strong>t utilityscale b<strong>at</strong>tery storage system.<br />
Xtreme Power’s dynamic power resources was installed, blessed <strong>and</strong><br />
placed in oper<strong>at</strong>ion in the fourth quarter of this year <strong>at</strong> the <strong>Koloa</strong><br />
Subst<strong>at</strong>ion.<br />
As reported earlier this year, this storage system<br />
will help mitig<strong>at</strong>e the effects of a 3megaw<strong>at</strong>t<br />
photovoltaic project, which also will feed into<br />
<strong>Koloa</strong>. In support of KIUC’s commitment to<br />
incorpor<strong>at</strong>e gre<strong>at</strong>er amounts of renewable energy,<br />
KIUC management <strong>and</strong> staff sought solutions to<br />
effectively integr<strong>at</strong>e large, intermittent gener<strong>at</strong>ion<br />
resources into its system, as necessary, to remain<br />
consistent with the coop’s str<strong>at</strong>egic goals <strong>and</strong><br />
initi<strong>at</strong>ives.<br />
KIUC has distinctive challenges with regards to<br />
stability. Solar systems are subject to output<br />
unevenness due to factors such as clouds passing<br />
over an install<strong>at</strong>ion.<br />
The addition of the b<strong>at</strong>tery storage system will<br />
allow KIUC to smooth the power output from PV<br />
projects by providing real <strong>and</strong> reactive power,<br />
compens<strong>at</strong>ing for sudden output fluctu<strong>at</strong>ions in a<br />
m<strong>at</strong>ter of milliseconds. Th<strong>at</strong> will allow for a more<br />
predictable flow of power from the PV system to
