| Cape
Wind Scientific Monitoring Station ~ Current Conditions
In preparation
for America’s first offshore wind farm, - capable of
powering on average three-quarters of the Cape and Islands
with clean, renewable energy - Cape Wind has erected a meteorological
data tower on Horseshoe Shoal, in Nantucket Sound. As part
of our continued commitment to the community we are providing
current weather and sea conditions to the public.

EDST • Wind speed, direction and gust, air
temperature and pressure are updated every 10 minutes.
We have gathered all of the
sea temperature, current, and wave data we need for
the design and engineering of the wind farm. We have
removed the equipment from the sea bed and will no longer
be posting these data on the website. We will continue
to post the wind, pressure, and air temperature data
on our website as well as the potential output of the
wind farm and emissions reductions.

Power
output is based on wind speed at 75 meters above surface.
The average electric demand of the Cape & Islands is 230 MW [from NSTAR].
If
Cape Wind were running today, we would be offsetting
emissions from other regional sources of electricity.
Exactly which fuel source we will offset is difficult
to quantify because the "mix" of energy
sources being utilized by the grid is based upon non-public
price information and varies from hour to hour. However,
over the past hour, generating the same amount of
energy from oil, coal or natural gas would have created
the following estimated emissions.
