The community-oriented Sterling projects are co-owned by Canadian Solar and
INDU Solar Holdings - a joint venture between subsidiaries of Duke Energy and
of Integrys Energy Services. The ground-mounted installations were developed
by Community Energy Solar and constructed by groSolar using 9,968 CS6P 240W
Canadian Solar modules. They will supply enough energy to power about 400
homes annually.

Sterling Municipal Light Department (SMLD) is purchasing the power generated
from the projects under 20-year agreements for use within the Town of
Sterling.

"These projects stand to have a significant impact on the Town of Sterling,
highlighting how a solar installation can support a community by providing
benefits on multiple levels, in addition to generating long-term clean
energy," said Dr. Shawn Qu, Chairman and CEO of Canadian Solar."We are pleased
to see this initial venture with INDU Solar come to fruition, and look forward
to future collaboration with INDU and our other project partners."

"On behalf of INDU, we are pleased to announce these project completions, our
first in New England," said Duke Energy Renewables President Greg Wolf. "All
of the stakeholders involved contributed a wealth of project development,
construction, and management expertise, and we are excited that Sterling will
benefit from this energy source for years to come."

Community Energy Solar worked closely with the Town of Sterling and landowner
Davis Dairy Farmland to design projects that are well suited for the
agricultural and residential setting and meet the town's long-term power
needs. Canadian Solar, Duke Energy Renewables, Integrys Energy Services and
Community Energy Solar are also facilitating a solar energy educational
initiative associated with the projects.

A ribbon-cutting ceremony for the projects will be held this summer in the
Town of Sterling. Canadian Solar and INDU Solar have already begun
construction on a third project developed by Community Energy Solar in
Massachusetts, a 3-MW (AC) installation in the southeastern part of the State.
