How Germany’s new renewables policy will affect wind power financing

Germany’s leading economics institute DIW has published a 36-page report in English on how the amendments to the Renewable Energy Act (EEG) will impact the cost of capital for wind power investors. They find that greater risks will increase the cost of borrowed capital – thereby making this aspect of the transition more expensive. read more »

Solar energy towers: harvesting R&D dollars for decades

Today, we are pleased to have a guest post by wind energy expert Mike Barnard, who looks into a technology that has been promising for many years now. But is it solar or wind? And more importantly, when is it time to say we are good to go with the stuff we have – and we don't need to wait for a breakthrough? read more »

On-site wind power is successful Nordex

On-site wind power is successful

Hamburg container terminal, Eurogate, started self-generating electric power about a year ago and is already exceeding expectations. Considering that the Nordex wind turbine installed in August 2013 generates power almost constantly, Eurogate now plans to replicate the model. But the surcharge to be applied starting later this year to such power consumed directly will slow down such projects. read more »

First municipal offshore wind farm awaits grid connection

The project is unique: forty 5 MW Areva wind turbines have been installed in the North Sea off the coast of Borkum by a consortium of municipals. The entire wind farm has been ready to go since the beginning of the month. The grid operator simply cannot provide a connection. German power customers now get to pay for the power anyway. read more »

Field converter plagues German offshore

The capacity factor of German wind turbines fell to a surprisingly low 14.1 percent in May – even lower than the CF of PV. A failed converter run by TenneT at the 400 MW Borkum offshore wind farm was part of the problem. Bernard Chabot provides the numbers. read more »

More offshore and system integration

The first WindEnergy trade fair in Hamburg since 2006 will take place in September. With about 1,000 exhibitors and 40,000 visitors, it will be about the same size of the last WindEnergy trade fair in Husum two years ago. Hamburg Messegesellschaft is organizing this event. They aim to set new priorities. read more »

A cost comparison of onshore and offshore

Bernard Chabot is back today with a comparison of his "silent wind revolution" (larger swept area relative to generator size) in the offshore and onshore sectors based on a Dutch offshore project. He finds that offshore remains more expensive, but also that the margins are nearly twice as great. read more »

Technical defect dampens German offshore wind power

Today, Bernard Chabot reviews wind power data up to April 2014 in Germany. One salient finding was the sharp downturn in power from offshore wind due to a capacitor failure on March 23. read more »
