GSK and ACE Launch Largest Solar Rooftop Array in U.S.

GlaxoSmithKline Consumer Healthcare

Begins Installation of North America’s
Largest Rooftop Solar Array

YORK, PA (October 28, 2010) – GlaxoSmithKline (NYSE: GSK) Consumer Healthcare is taking its commitment to renewable energy to the next level.  Today, GSK begins installing North America’s largest rooftop solar array at its Northeast Regional Distribution Center (RDC) in York, Pa.  GSK’s sustainability initiatives were just recognized in Newsweek’s “2010 Green Ranking” as ranking fifth among the greenest companies in the world.

Nearly 11,000 solar panels will cover an area on the roof which is about the size of seven American football fields.  The solar panels will generate enough electricity to meet the annual energy needs of the nearly 500,000 square foot building.  That’s equivalent to the power needed each year for almost 400 average sized homes.

“This solar rooftop array is a demonstration of GlaxoSmithKline Consumer Healthcare leadership not just in solar power, but in sustainability,” said John Clarke, president of GlaxoSmithKline Consumer Healthcare. “We hope that GSK’s renewable energy strategy will inspire other companies to look for ways to protect our planet.”

Solar Panel Installation

Each solar panel weighs about 60 pounds and is more than six feet long and more than three feet wide.  The panels are installed in a grid system in sets of three.  Nearly 100 workers will spend the next two months hoisting the panels to the roof with a crane, securing them into place and networking them into the power system.  American Capital Energy, the company responsible for the project, plans to install about 500 panels per day.

The 3-megawatt system is expected to generate approximately 3.4 million kilowatt hours of energy per year.  This will enable the facility to reduce carbon dioxide emissions by

3,000 tons annually.  It would take nearly 15,000 trees to absorb that much carbon dioxide in a single year.  When the project is completed, it will be the first time a GSK facility anywhere in the world will be completely reliant on solar energy.

Government Incentives Key to Project’s Start

“Solar power is helping to propel Pennsylvania towards a new era in sustainable industry,” said Andrew Place, Acting Deputy Secretary for the Pennsylvania Department of Environmental Protection. “We need strong advocates such as GlaxoSmithKline Consumer Healthcare to help us achieve this goal. The installation of this solar project shows how private sector leadership can help us all achieve a greener future. I urge other Keystone State companies to follow their lead.”

GlaxoSmithKline Consumer Healthcare received government funding and solar incentives to help finance the project.  A $1 million grant from the Commonwealth of Pennsylvania, Commonwealth Financing Authority and $4.1 million in federal tax credits will help pay for the project. GSK will also utilize energy savings and Solar Renewable Energy Credits (SREC) to offset costs.

“The support of state and federal leaders is instrumental in helping GSK expand our solar energy initiatives,” said Larry Brown, Vice President, North America Supply, GlaxoSmithKline Consumer Healthcare.  “This solar panel array provides a blueprint for GSK to bring solar power to each of its North American distribution facilities in the next few years.  As a next step, we will then install solar panels at our Fresno, Ca. RDC by spring of 2011.  Together, the York and Fresno facilities will generate 60 percent of the total GSK Consumer Healthcare North America RDC electricity supply from clean renewable solar energy. This is a remarkable step toward us becoming a more energy-efficient company”

Four other solar panel projects were recently completed at GSK facilities in Upper Providence and Collegeville, Pa., North Carolina; Belgium and Singapore.
