IEEE Electrification Magazine - March 2015 - 5

ComEd with an invaluable experience
in transforming the traditional way of
electricity supply and delivery and
gaining first-hand knowledge
on future integrated grids but also
paves the way for other utilities that
understand the urge to adopt new
business models and are ready to
embrace changes.
The fifth feature, "Islands in the
Sun," is coauthored by Wayne
Archibald, Zuyi Li, Mohammad Shahidehpour, Steve Johanns, and Tom Levitsky. The authors are the architects
for deploying 3.3 MW of solar power at
the University of the Virgin Islands
(UVI). UVI's two campuses considered
for the installation include the
St. Thomas campus and the Albert A.
Sheen campus on St. Croix. This solar
power deployment initiative will
reduce UVI's dependence on fossil
fuel by 50% by 2015. The photovoltaic
system will use approximately 5.7
acres on the St. Thomas campus and
3.9 acres on the Albert A. Sheen campus on St. Croix. This system is
expected to produce 5.9 million kWh
annually at the St. Thomas facility and
2.4 million kWh annually at the St.
Croix facility.
The U.S. Virgin Islands has 110,000
residents, but its energy prices are four
to five times higher than those in the
continental United States. Like many
islands, the U.S. Virgin Islands is
almost 100% dependent on imported
oil for electricity and water generation.
Residents pay about US$0.57/kWh to
light their homes and run their appliances, which is higher than 275% of
the national average per unit cost
benchmark of US$0.33/kWh. The solar
power deployment initiative will
reduce UVI's electricity price to
US$0.34/kWh (33% reduction) via distributed solar power and an advanced
storage system. The avoided electricity
cost is expected to be about US$11
million for the first eight years (39%
reduction) and about US$37 million for
the first 25 years (52% reduction). The
total budget of the solar power deployment initiative is US$13.136 million,
