POWER EFFICIENCY CASE STUDY
Walgreens - Yonkers, NY
Businesses Look to Save Money by Using Power More Efficiently
with Green Charge Network’s GreenStation
Project Description
Operating over 8,000 retail health and drugstore outlets across
the U.S., Walgreens is all about helping Americans improve and
maintain health and fitness. Hand-in-hand with this commitment, Walgreens, like a large and growing number of U.S. businesses, is also intent on enhancing the social and environmental, as well as economic, sustainability of its operations.
In 2012, Walgreens installed a greater number of solar energy
systems than any other company in the U.S. barring Walmart.
This year, the nationwide retail health and drugstore chain operator became the first company of its kind to install an intelligent
energy storage system. Signing a Power Efficiency AgreementSM
(PEASM) with Green Charge Networks, Walgreens is becoming a
leader in the fast emerging U.S. energy storage space.

POWER EFFICIENCY CASE STUDY
Walgreens - Yonkers, NY
Project Description, continued
A GreenStationTM intelligent energy storage system was first installed at a Walgreens retail outlet in Yonkers, New York, near
the banks of the majestic Hudson River. The 27kW / 64kWh
GreenStationTM is expected to save Walgreens up to 50% in demand charges in the summer when peak demand charges are
high.
The Problem
National retail chains like Walgreens have large energy and ecological, as well as economic and geographic, footprints. High
and volatile fossil-fuel energy costs, along with the long-term
impacts of fossil-fuel energy use on human and environmental
health and safety, has led the New York State government to
join with utilities, businesses and local communities to identify
and implement sustainable “green” energy and energy efficiency solutions.
The rising costs of peak-demand electricity usage and the strain it puts on aging electricity grids led Walgreens to search
for a cost-effective means of reducing power consumption and enhancing power efficiency. The national retailer turned
to Green Charge Networks and its GreenStationTM intelligent energy storage system for a solution.
Our Solution
Environmental Savings
By committing to reducing energy usage and
expanding on their renewable energy initiatives,
Walgreens is sparing the environment from the
effects of harmful emissions such as automobile
emissions, industrial emissions and the emissions
from the power plants still using coal. Commercial
buildings account for 18% of US CO2 emissions (*).
Through Green Charge’s GreenStationTM, building
owners can save up to 50% on their electricity bills.

Green Charge Networks’ GreenStationTM actively minimizes
monthly peak electricity demand usage as measured by the utility meter. Historical and live streaming data points are posted
into a cloud based data warehouse where an automated network operation center uses heuristic and predictive algorithms
to determine an optimized maximum peak demand value.
As GreenStationTM gains experience, it learns the site-specific
characteristics of the facility’s load profile and adjusts the second-by-second charge / discharge profile to minimize utility demand charges. That can lead to substantial reductions in peak
power demand and associated utility charges, as well as enhance the reliability of on-site electricity supply.
In addition, Green Charge Networks’ Power Efficiency AgreementsSM (PEAsSM) make financing easy. A pay-for-performance
contract, Green Charge PEAsSM eliminate the need for GreenStationTM users to invest any capital up-front. Green Charge takes
care of project design and installation, as well as operations
and maintenance. Resulting electricity bill savings are shared
between Green Charge and the customer.
