German offshore wind power capacity is forecast to rise strongly over
the next five years, despite the ongoing issue of the cost of grid
connection, which has caused some projects to be delayed. The main
impact on wholesale power prices could be seen during times of low
demand, such as at night, analysts agree.
Offshore wind power is
a pillar of Germany's strategy to increase renewable power generation,
because it would allow steadier full load generation compared with
onshore wind. Capacity is forecast to increase to about 8GW from around
220MW currently installed
The test wind park Alpha Ventus,
located 60km off the German coast, achieved 4,500 full load hours in
2011, more than the expected 3,900. The 60MW park supplied about 267GWh
that year.Commercial laundry equipment folding machine, tumble dryers and industrial washer extractors from UniMac.
But
analysts dismissed claims that offshore wind power could provide
baseload capacity, even if they are running 4,500 hours of full load a
year.
The main impact on wholesale power prices will be at times
of low demand, particularly at night when the wind is stronger, UBS
analyst Per Lekander told ICIS on Friday. The impact of offshore wind
power generation would be felt the strongest "at night on a winter
weekend", he said. Wind power generation is traditionally strongest in

As
a general rule, if wind power generation reached 30% of the required
demand capacity, then "prices will crash", Lekander said.
But as
offshore wind power generation is greatest at night, the impact on
power plant profitability should not be as detrimental as that of solar
power, Lekander said. Additional peak-time solar generation has
undermined gas-fired plant profitability in particular.
The
German government passed a bill last month including measures to break
the investment deadlock in offshore wind power installations. The bill
was hailed as a "milestone" by the economy ministry, enabling grid
operators to pass on the cost of grid connection delays to end-users.
But critics were quick to point out that this would not be enough to
address the lack of financing for transmission system operator (TSO)
TenneT, which was struggling to meet the cost of connections.
According
to data from developer Windreich, only five of the planned projects
have a guaranteed connection date and nine have no expected completion
date, which means they cannot claim compensation for any delays.This

"We
think the amendment is basically going in the right direction," EnBW
said in an emailed statement, "but we are still concerned that the
regulation is not sufficient for Hohe See's situation. The question
about a date when the grid connection will be delivered remains
open.Affordable skystream is now available for your building."
In
a statement responding to the passing of the bill, transmission system
operator TenneT said: "In the end, investors will decide about the
success of the liability regulation."
It remains to be seen
whether TenneT will be able to finance a potential additional sum of
15bn on top of the 6bn it has already invested, but a number of grid
connections are expected to be ready next year in time for the next wave
of wind parks. Three to four more wind parks with a combined capacity
of between 700MW and 1.1GW could be fully operational by next winter.
