400 MW Grid Interconnection Approved Between Denmark & Germany

400 MW Grid Interconnection Approved Between Denmark & Germany

written by James Ayre

The government of Denmark has approved an application for a new grid interconnection with Germany, according to recent reports.

To be more specific, the Danish Minister for Energy, Utilities and Climate, Lars Christian Lilleholt, approved Energinet.dk’s application to invest into a new interconnection through the Baltic Sea (between the Eastern Danish and German electricity grids).

As it stands, grid investments in Denmark exceeding DKK 100 million require approval from the country’s Minister for Energy, Utilities and Climate. The new interconnection will feature a capacity of 400 megawatts (MW), and will be developed jointly by Energinet.dk and 50 Hertz (a German transmission system operator).

The project will apparently be the first in the world to interconnect the offshore wind farms of two different countries.

Energinet.dk provides more:

The Minister’s approval is important and helps create the future, cross-border electricity market, where much more electricity must be traded back and forth across borders. On the one hand, Danish power stations and wind turbine owners can sell more electricity to German consumers and make a profit on it. On the other hand, Danish consumers can buy electricity in Germany, for example when the wind is not blowing and the wind turbines are not spinning. This makes the green transition less expensive and more effective, said Torben Glar Nielsen, Executive Vice President, CTO, at Energinet.dk.

…The Danish offshore wind farm, Kriegers Flak, which the Folketing decided to erect in the Baltic Sea based on the energy agreement from 2012, will be connected to the submarine cables, which run from the German side to the two German offshore wind farms Baltic 1 and Baltic 2.

…The unique Combined Grid Solution (CGS) can thus not only transport electricity from three offshore wind farms to consumers in the two countries, it can also export electricity from power stations, onshore wind turbines, solar cells, etc to consumers in the other country. As the interconnection connects two different electricity areas, it is necessary to build a facility in Bentwisch which can synchronise electricity from the Eastern Danish and German systems.

The connection is expected to be ready by the end of 2018, and will feature a budget of €320 million. The EU is apparently putting €150 million from the European Energy Programme for Recovery into the project.

Is this Infographic on Electric Vehicles Right?

written by Walter Wang

Here’s an infographic (see below) from the Union of Concerned Scientists on electric transportation, whose point is that, where only 1% of the cars on roads currently are EVs, 42% “could be” – meaning that their drivers meet all the criteria: dedicated parking, limited range, no towing, no need to transport full soccer teams, etc. The piece

How Solar Tech is Breeding Independence from The Grid

written by Walter Wang

For thousands of years, the sun has been revered by many cultures for its enormous power and size. Now, people are admiring the giant star for a very tangible reason: its ability to help lower electric bills. Installing solar panels will save the average person around $1000 a year on their energy bills, notes SolarEnergy.net – not too shabby!

Their Own Sunny Idaho

written by Walter Wang

Rooftop solar rights recently scored another win! This one from Idaho where the state’s major utility, Idaho Power Company (IPCo) had set out to weaken its net metering program and otherwise penalize solar customers by changing their rates. Well, the verdict came out July 3rd, and the Commission stood strong for Idaho’s rooftop solar customers.

The Smart Grid and Electric Car Charging

written by Walter Wang

Widespread adoption of electric vehicles will reduce greenhouse gas emissions significantly. Some are worried that the electric grid will be stressed leading to a decrease in its reliability. In related news today, Battelle and AeroVironment have a technology that will address this concern, and help EV’s charge when the grid is most able to support charging.

São Paulo To Pilot Grid-Connected Solar Farm

written by Walter Wang

Brazil is known for its non-fossil energy matrix largely thanks to its reliance on hydropower, which comes with its fair share of controversy as the case of the mega dam Belo Monte exemplifies. Wind power is starting to grow in the country but solar photovoltaic is still a minuscule, virtually non-existent industry.

Therefore, it comes as good news that the fifth global

The Migration to Electric Vehicles — It’s Complicated

written by Walter Wang

Here’s an overly simplistic article that questions the validity of electric vehicles as “green” transportation, suggesting that charging EVs can require more coal to be burned. I note the comment: “I power my electric car totally from solar PV panels. This article should be citing coal-fired power plants, not electric cars.” He has an excellent point, but, since most EV

What’s Old is New Again – Revisiting Energy Storage

written by Walter Wang

The electrical grid is a complex network connecting thousands of power sources with millions of consumers all across the U.S. While producing enough power to supply the energy needs of a nation is an extremely difficult task, just as challenging, if not more so, is the need to balance supply and demand on the grid.
