ENERCON Cold Climate Solutions
EFFICIENT AND SAFE TECHNOLOGY WHERE THERE IS A RISK OF ICE FORMATION
Extreme climate conditions like those at Cold Climate sites demand flexibility and specialised technological solutions. In the winter
months in particular, it is entirely possible that ice formation will also occur on rotor blades. This can lead to loss of yield or may
even cause a standstill of the wind turbine. ENERCON’s sophisticated ice detection technology has been working to counteract
this since 2004. All ENERCON wind energy converters can be delivered as cold climate versions, meaning that the power curve at
WEC operation is not affected at temperatures above -30°C. This helps to reduce any downtime and losses of yield to a minimum.

Sailing into the
wind power business
The interest in sailing was one of the reasons why Canadian Matthew Wadham-Gagnon, part
of the Winterwind program committee, ended up in the wind power industry.

Winterwind
- An internationally established
meeting place
Winterwind is probably the world’s largest cold-climate-focused
windpower conference. In addition to being a very important
meeting place for industry representatives, the goal is to
contribute to solving the practical problems that, among other
things, low temperatures, icing, large distances and complex
terrain cause.

Ice accretion on rotor blades may cause severe
production losses for wind turbines in cold
climates. Previous studies have shown that ice
may cause production losses by up to 13 percent
in a year. In certain months, when conditions are
particularly likely to cause ice accretion, more
than half of the expected production may be lost.
In extreme cases, ice may cause production to
stop for days, or even months.

A meeting point for potential buyers and sellers of
renewable energy Power Purchase Agreements (PPAs)
Meet with potential buyers and sellers of renewable energy at Re-
Scandinavia’s event for the most affordable technologies such as
wind power and solar power. Corporate renewable energy PPAs are
attracting much attention – politically and among renewable energy
investors.
For whom?
The suppliers of electricity gain from the long-term revenue stability
of the Corporate PPAs while the offtakers of long term renewable
energy contracts gain an easily identifiable supply of renewable
energy, thus mitigating the risks of price hikes.
Why attend?
Inspiring and instructive presentations brought to you by centrally
placed players in the field of power purchase agreements. And get
a chance to look into the structure and outlook of major deals within
the market. Take part in knowledge sharing and networking, and not
least matchmaking for new business opportunities.
Welcome to Malmö – we look forward to seeing you!
