Helping developers map out renewable energy

Mar 3 - McClatchy-Tribune Regional News - Angel Gonzalez Seattle Times
Remember the thrill of checking out your house from outer space with Google
Earth? Now a Seattle company wants you to know whether there's enough wind
to power it with renewable energy.
3Tier, a weather-consulting service geared toward renewable-energy
developers, is expected to release a global wind map, available free on the
Web.
The company also aims to create a similar tool to portray the potential of
solar energy, to be released within the next 18 months.
The wind map doubles as evangelism for Aeolic energy and as a promotional
tool for 3Tier. It will provide average yearly wind data over a 15 square
kilometer area; if users are interested, they can request a more detailed
report from the company.
Until now the data for the U.S. has been available on the company's Web
site, but 3Tier founder Kenneth Westrick wanted it to be available to
decision-makers across the developing world.
The 30 percent of the globe's population that lives without electricity
faces an "information barrier," Westrick said.
If politicians and entrepreneurs know their regions have potential for wind
farms or solar arrays, they could start planning them, he said.
"Profitable" speeds
For a wind project to be profitable, wind speeds must reach an annual
average of 6 meters per second. But it also needs to be near transmission
lines that reach population centers.
According to 3Tier's map, the Washington Coast and the Olympic Peninsula are
quite breezy but they're too remote, says 3Tier President Pascal Stork.
"You can't just build a wind farm where it's windy. You need to get the
energy out," he said.
Eastern Washington, on the other hand, has ample transmission capacity,
built to serve hydroelectric power generated from dams. That, combined with
sufficient wind speed, makes it prime wind farm country, Stork said.
In the global map, Africa stands out as a region with a lot of wind
potential, Stork said. But lack of transmission capacity remains a roadblock
there.
Westrick, a former University of Washington researcher, started 3Tier in
2001, anticipating that renewable energy would become a booming business.
The company models and monitors weather patterns that affect solar, wind and
hydroelectric projects; nowadays power purchasers, traders, utilities and
alternative energy developers buy 3Tier's products.
Payroll doubles
Its payroll has doubled in the past year to more than 50 employees, many of
them atmospheric scientists, Stork said.
Almost all of its products are delivered through the Web. In 2007 revenues
reached $4 million, 70 percent more than the previous year.
3Tier, a closely held company, last year raised $2 million from Good
Energies, an investment fund specialized in renewable energy.
Closely following the weather allows operators to predict when a source of
energy might peak, or fail.
"Forecasts help maintain grid stability," Stork said.
