Connecting 25 gigawatts of offshore wind to the grid among the goals

Germany Plans 3800-Kilometer, $25 Billion Transmission Network for Wind Power

Fresh off the record-setting solar weekend in Germany, the country's transmission operators say plans are in the works for a huge transmission line buildout to accommodate growing wind power resources.

The goal is to build 3800 kilometers (more than 2300 miles) of high-voltage lines—2100 km direct current lines and 1700 alternating current lines—stretching from the coasts of the Baltic and North Seas toward the southern parts of the country. The North Sea is already home to a few offshore turbines (and the government wants about 10 gigawatts of offshore wind installed by 2022 in order to help meet the country's renewable energy goals). By 2030, the hope is that more than 25 gigawatts will be installed—something on the order of 5000 turbines, depending on size.

Transmission is no easy thing to build, however. The new lines will cost around €20 billion (close to $25 billion), and there will need to be some serious buy-in from the public and politicians alike to get the project done. "We need to see a closing of ranks with politics to make sure the network expansion works," said Klaus Kleinekorte, CEO of transmission operator Amprion, in the Financial Times.

He emphasized the importance of starting on these projects as soon as possible with the aim of having them delivering power by 2020 at the latest. Germany will spend the next few decades in a bit of an energy crunch, having already taken some nuclear plants offline after Fukushima and the remainder scheduled to be totally shuttered by 2022. The strained grid will face a higher risk for big blackouts as nukes shut down and renewables come online, which good new transmission networks could ease.

And that $25 billion price tag may seem steep, but it's just a tiny part of the overall energy picture in Germany. Earlier this year, Siemens estimated that the nuclear phaseout overall could cost more than $2 trillion. It's refreshing to see the country staring some of these big energy issues so full in the face—even with logistical and cost difficulties everywhere, Germany is clearly not fooling around when it comes to renewable energy.

This photograph shows a car with the words “We Drive Solar” on the door, connected to a charging station. A windmill can be seen in the background.

The Dutch city of Utrecht is embracing vehicle-to-grid technology, an example of which is shown here—an EV connected to a bidirectional charger. The historic Rijn en Zon windmill provides a fitting background for this scene.

We Drive Solar

Hundreds of charging stations for electric vehicles dot Utrecht’s urban landscape in the Netherlands like little electric mushrooms. Unlike those you may have grown accustomed to seeing, many of these stations don’t just charge electric cars—they can also send power from vehicle batteries to the local utility grid for use by homes and businesses.

Debates over the feasibility and value of such vehicle-to-grid technology go back decades. Those arguments are not yet settled. But big automakers like Volkswagen, Nissan, and Hyundai have moved to produce the kinds of cars that can use such bidirectional chargers—alongside similar vehicle-to-home technology, whereby your car can power your house, say, during a blackout, as promoted by Ford with its new F-150 Lightning. Given the rapid uptake of electric vehicles, many people are thinking hard about how to make the best use of all that rolling battery power.
