Project development company RES Deutschland GmbH (Renewable Energy Systems) has won a contract put out to tender by Versorgungsbetriebe Bordesholm (VBB) for the construction of a 10-MW battery storage system to supply reserve power. In addition to supplying an operating reserve, the battery storage system will operate as a stand-alone power system to provide back-up power to the region – sourced primarily from renewables – in the event of a mains network failure. The state of Schleswig-Holstein is providing financial support to fund the pilot of the stand-alone power system. For global project development company RES, the project is the first multi-megawatt storage project on German soil.
The dismantling of conventional power stations and the increased use of renewable energy sources means that new, more flexible frequency stabilisation solutions are required. Depending on the situation, and whether there is an excess or shortfall of energy in the supply network, the use of power from volatile sources can cause fluctuations in frequency which, in turn, can result in problems. By installing a new battery storage system on its own site, Versorgungsbetriebe Bordesholm (VBB) is helping to stabilise the network. The municipality already meets 75 per cent of its annual energy needs with renewable sources. The storage system is designed to provide energy for a limited geographical area – with no interruption to supply – in the event of a fault in the main grid or the total failure of the upstream network. The Bordesholm battery storage system will boast a marketable output of 10 MW, with a storage capacity of 15 MWh.
Battery storage systems: A growth market
Battery storage systems, like those offered by the RES Group for the German and European markets, are ideal for system service applications: If surplus energy is available, they store it and feed it back into the network in a fraction of a second when demand starts to exceed supply, making them a fast, cost-effective and environmentally friendly solution. "We're pleased to be able to work with RES – a company with many years of experience in the global storage solutions market – as a partner for our pilot project. The bid submitted by RES demonstrated a high level of technical expertise, and we were impressed by the detailed concepts and exceptionally competitive pricing", says Frank Günther, Managing Director at VBB.
The technical specifications for the project are demanding: In addition to a closed network infrastructure, the storage system must be equipped with additional features such as synchronous coupling switches. The system will also incorporate a powerful fibreglass network to enable real-time communication between the technical components and customers.
Dr. Matthias Leuthold, Head of Energy Storage Systems at RES Deutschland GmbH: "The RES Group has already implemented numerous energy storage projects for network services in the UK, USA and Canada. We're really pleased to have won the contract with VB Bordesholm. This is an important step towards bringing our expertise to the German market. Reserve power is a cost-effective solution that will grow in importance over the coming years, including in Germany, as we continue to phase out fossil fuels."
Construction work on the storage system in Bordesholm is set to commence in summer 2018; VBB plans to commission the system in spring 2019. Upon completion of the pilot, the findings from the research will be available to research institutions as a source of data for further investigations. Furthermore, the storage system is expected to generate annual revenue of around a million euro by providing reserve power for the primary energy market.

Der Projektentwickler RES Deutschland GmbH (Renewable Energy Systems) hat die Ausschreibung der Versorgungsbetriebe Bordesholm (VBB) für den Bau eines 10 MW-Batteriespeichers zur Erbringung von Regelleistung gewonnen. Zusätzlich zum Regelbetrieb soll der Batteriespeicher beim Ausfall des übergeordneten Netzes die kommunale Stromversorgung im Inselnetzbetrieb aus überwiegend erneuerbaren Energien sichern. Die Erprobung des Inselbetriebs wird als Pilotprojekt vom Land Schleswig-Holstein gefördert. Für den international erfahrenen Projektentwickler RES ist es das erste Multimegawatt-Speicherprojekt in Deutschland.
Der Rückbau von konventionellen Kraftwerken und die verstärkte Einspeisung von erneuerbaren Energien erfordern neue, flexiblere Lösungen für die Frequenzstabilisierung. Durch die Einspeisung von Strom aus volatilen Erzeugungsquellen kann je nach Situation zu viel oder zu wenig Energie im Stromnetz zu Frequenzschwankungen und damit zu Problemen führen. Die Versorgungsbetriebe Bordesholm (VBB) tragen mit einem neuen Batteriespeicher auf dem eigenen Firmengelände zur Netzstabilisierung bei. Die Kommune deckt bereits 75 Prozent ihres jährlichen Strombedarfs aus regenerativer Erzeugung. Zusätzlich soll der Speicher bei Störungen in der Stromversorgung über das Hauptnetz oder bei einem kompletten Ausfall des vorgelagerten Netzes ein regional begrenztes Gebiet weiter mit Energie versorgen – ohne Unterbrechung der Versorgung. Die vermarktbare Leistung des Bordesholmer Batteriespeichers wird 10 MW betragen, bei einer Speicherkapazität von 15 MWh.
Batteriespeicher, wie sie die RES Gruppe für Deutschland und Europa anbietet, sind bestens zur Erbringung von Systemdienstleistungen geeignet: Bei einem Überangebot an Strom nehmen sie Energie auf und geben sie bei einer Unterversorgung binnen Sekundenbruchteilen wieder in das Netz zurück – schnell, kostengünstig und umweltfreundlich. „Wir freuen uns, mit RES einen Partner für unser Pilotprojekt gefunden zu haben, der mit langjähriger Erfahrung am internationalen Speichermarkt punkten kann. In der Ausschreibung hat uns das Angebot von RES aufgrund der technischen Kompetenz, der Qualität der detailliert ausgearbeiteten Konzepte und letztlich auch der sehr wettbewerbsfähige Preis überzeugt“, erläutert Frank Günther, Geschäftsführer der VBB.
Die technischen Voraussetzungen für den Betrieb sind anspruchsvoll: Neben einer geschlossenen Netzinfrastruktur ist unter anderem ein Speicher mit zusätzlichen Erweiterungen wie Synchron-Kuppelschaltern erforderlich. Zur Echtzeit-Kommunikation zwischen den technischen Komponenten und den Kunden dient außerdem ein leistungsfähiges Glasfasernetz.
Dr. Matthias Leuthold, Leiter Energiespeicher bei der RES Deutschland GmbH: „Die RES Gruppe konnte bereits eine Vielzahl an Speicherprojekten für Netzdienstleistungen in Großbritannien, den USA und Kanada umsetzen. Die gewonnene Ausschreibung der VB Bordesholm freut uns sehr. Sie ist ein weiterer wichtiger Schritt, um unsere Expertise auch in Deutschland einzubringen. Denn die Bereitstellung von Regelleistung wird in den kommenden Jahren aufgrund ihrer hohen Wirtschaftlichkeit und der fortschreitenden Ablösung von konventionellen fossilen Energieträgern auch in Deutschland weiter an Bedeutung gewinnen."
Baubeginn für den Speicher in Bordesholm ist im Sommer 2018, mit der Inbetriebnahme rechnen die VBB im Frühjahr 2019. Die Erkenntnisse des Forschungsvorhabens stehen nach Abschluss des Förderprojektes Forschungseinrichtungen als Datenquelle für weitere Untersuchungen zur Verfügung. Darüber hinaus soll der Speicher durch die Bereitstellung von Regelenergie für den Primärenergiemarkt Jahreserlöse von rund einer Million Euro einbringen.
This is what America's eco city of the future looks like
Georgetown mayor Dale Ross is ‘a good little Republican’ – but ever since his city weaned itself off fossil fuels, he has become a hero to environmentalists
by Tom Dart in Georgetown, Texas - The Guardian
When the caller said he worked for Harry Reid and the former Senate majority leader wanted a word, Dale Ross assumed it was a joke. “OK, which of my buddies are messing with me today?” he wondered.
He shouldn’t have been so surprised. Ross is the mayor of Georgetown, population 65,000, and he has become a minor celebrity in environmental circles as a result of a pioneering decision in 2015 to get all the city’s electricity from renewable sources.
Georgetown’s location in oil-and-gas-centric Texas and Ross’s politics add to the strangeness of the tale. The mayor is a staunch Republican at a time when a Republican president – and his Environmental Protection Agency administrator – reject the scientific consensus on climate change and are trying to revive the declining coal industry.
Ross has appeared in a National Geographic documentary, a forthcoming film about clean energy for HBO directed by James Redford (son of Robert) and in this year’s follow-up to An Inconvenient Truth, which saw the advocate and former vice-president Al Gore visit Georgetown.
The day after we met at city hall, just off Georgetown’s charming main square, Ross was set to fly to Utah to introduce a screening of An Inconvenient Sequel: Truth to Power. Then it was on to Las Vegas to reunite with Gore, a fellow speaker at Friday’s National Clean Energy Summit, an event co-hosted by Reid, a Democrat from Nevada. Next week, a conference in Oakland, California. Next month, a green energy panel in Nova Scotia.
“You should see the fan mail that I get, especially with the movies,” Ross grinned. The 58-year-old said the decision to follow the lead of Burlington, Vermont – the first US city to run solely on renewable energy – was not the product of liberal do-gooder vapours wafting up Interstate 35 from nearby Austin. It was based on cold-eyed pragmatism, the fruit of the kind of careful numerical analysis he performs in his day job as a certified public accountant.
“The revolution is here,” he said. “And I’m a good little Republican, a rightwing fiscal conservative, but when it comes to making decisions based on facts, that’s what we do.”
The facts, Ross said, are that when Georgetown negotiated power supply deals the cost was about the same between natural gas and wind and solar, but the natural gas option would provide only a seven-year guaranteed contract whereas 20-25 year proposals were on the table from renewable providers.
Georgetown officials decided to lock in a long-term rate to eliminate price volatility, mindful of the risk that future government actions might send fossil fuel costs soaring.
Prices in the city, Ross said, have declined from 11.4¢ per kilowatt hour in 2008 to 8.5¢ this year. Georgetown sources most of its power from a wind farm 500 miles away in Amarillo and will get solar energy from a farm in west Texas that is expected to be finished next June, meaning the city can attain its 100% renewable goal even when the wind isn’t blowing. This year, Ross said, the tally is about 90%, down from 100% in 2016.
“I think it’s a big step for Texas, for Georgetown,” said Christian Soeffker, who runs a toy shop on the square. “We just like the idea of being in a town that is in some ways special because we’ve got all that green energy.”
Georgetown makes headlines not only because so few US cities run entirely on renewables, but because it has a conservative mayor willing to make compromises and fraternise with high-profile Democrats in a hyper-partisan era where climate change is one of the most divisive subjects.
“How is anybody going to compete with wind and solar?” said Ross, who has ordered an electric-powered BMW scooter from California and plans to fit solar panels at his home and office.
All the same, he voted for coal’s biggest champion in last November’s presidential election – Trump was “like, my eighth or ninth choice” in the primary, he said – and went to his inauguration, which he said was “phenomenal”, even if it cost $700 for a basic hotel room. His support is not unquestioning, though.
“When Trump was campaigning he was talking about clean coal and we’re going to bring coal jobs back? That is a mirage, that is not going to happen,” he said. “Coal is one of the most expensive forms of fossil fuels to produce. And those jobs are never going to come back, ever. They’re done.”
As for any policies the federal government might enact to boost the coal industry, such as the decision announced on Tuesday to scrap the Obama administration’s Clean Power Plan?
“Isn’t that sort of like putting a Band-Aid on somebody that has terminal cancer?” Ross said. “I’m not the smartest guy in the room but it’s not that complicated, OK? How’s fossil fuels going to compete in the next five years? They’re not going to be able to compete.”
Texas is the US leader in wind energy capacity, even as many of its politicians maintain absolute fealty to fossil fuels that are a key economic driver and still the supplier of most of the state’s electricity. It has lagged behind other states in solar capacity but is starting to realise its potential.
“We have so much area in Texas that’s ideal for solar,” said Joey Romano, a 35-year-old with a small solar farm 50 miles west of downtown Houston. “Solar and wind, unsubsidised, today already can compete with coal,” he said.
Local Sun has about 100 residential customers. Completed at the end of 2015, the farm is located in a rural county that gave Trump 79% of the vote. But Romano said local officials recognised the potential for jobs and revenue and were happy to help the project get off the ground. Beehives stand among the 15,000 panels.
“We call the programme ‘farm-to-market solar energy’,” Romano said, at his office in central Houston.
Local Sun is a boutique operation in partnership with MP2 Energy, a retail company owned by Shell, and it is designed to attract those willing to pay a small premium for an eco-conscious local product, much as food shoppers might spend a little more for organic groceries.
However modest, its very existence feels like a significant marker in a city that is known as America’s oil and gas capital but is in fact the nation’s biggest municipal user of green power.
On the other hand, environmental activists worry that solar’s growth will be stunted in Texas and across the country if, as appears likely, the Trump White House imposes prohibitive tariffs on imported solar panels.
“They may harm thousands of installation jobs in favour of a few hundred manufacturing jobs, so that could hurt,” said Jim Marston of the Environmental Defense Fund, who believes renewable energy will thrive even if federal incentives end and barriers are erected.
“You can’t stop the technology. It’s too good, the prices are too good, and people want it,” he said.
Ross agrees that market forces will prevail. On Friday, the day of the clean energy summit, Texas’s largest electricity producer announced it would close two more coal-fuelled power plants in the state.
Luminant cited challenging economic conditions including low wholesale and natural gas prices and the growth of renewables. A week earlier, the company said that in January it will retire a large coal-powered plant in east Texas.
“We were on the frontier of the fossil fuel business, oil and gas,” Ross said. “And now Texas again is on the frontier of the new energy that’s going to be the future.”
