Webinar: When are commercial storage systems worthwhile?

April 26, 2018: In the context of the much-discussed energy transition, the use of large-scale storage systems is taking on an ever-greater role in commerce and industry, as well as for utilities. The aim is for storage systems to bridge the gap between the volatile infeed from renewable energy sources on the one hand and grid electricity demand on the other. As the grid is unable to store energy, exactly the same amount of power must be fed into it as consumers are drawing from it at any given moment. Linking up grids over large areas is of course another way to mitigate this issue. Economic assessments of storage system projects show that – with just a few exceptions – battery storage systems must perform multiple tasks to generate a good return on investment. As every task contributes to the storage system’s overall revenue, it is common to look at it in terms of multiple revenue paths that combine to give the total profit margin. Possible streams of revenue and cost savings include for example cutting peak loads, avoiding grid charges, atypical grid usage, marketing balancing power, optimizing self-consumption and providing reactive power.

The webinar with Hans Urban, a consultant in the field of renewable energies and e-mobility, will bring participants up to date on the latest expertise in this area.

The webinar has taken place on Thursday, May 17, 2018 at 4:00pm (in German only)

sonnen und Engie Agree on Partnership

April 26, 2018: Since 2017, PV self-consumption systems in France have been supported with an investment bonus. At the same time, the electricity price has risen by about 20% in the past five years. In order to offer the two-thirds of the French population who are interested in a photovoltaic installation the opportunity to offer self-generated electricity in the evening and at night, the storage provider sonnen and Engie have joined forces to offer the customer of the energy supplier a complete package for self-consumption. Under the name My Power they receive a PV system and a sonnenBatterie.
The French storage market is still in its early stages, but exactly for that very reason it has great potential. The cooperation gives sonnen access to 4.4 million homeowners and new customers.
sonnen already had its sonnenBatterie on the French market, certified it and trained numerous fitters on site. In addition to its  most important market Germany, sonnen also operates in other European countries, as well as in the USA and Australia.

End customers focus on a combination of electric mobility and photovoltaics

March 8, 2018: A current survey from EuPD Research reveals that German home-owners are highly interested in using cost-effective self-generated photovoltaic energy for their electric vehicles. Home-owners, who are currently considering the purchase of an electric vehicle, are also intent on buying a photovoltaic system. Furthermore, it is seen as the utilities’ responsibility to offer specific automotive electricity tariffs. more

Messe München: More than 20 charging stations for visitors of The smarter E Europe

January 26, 2018: At least since driving bans have loomed in big German cities like Munich, the subject of electric mobility has been relevant to society as a whole. Klaus Dittrich, Chairman & CEO of Messe München, thinks that companies in particular have a duty here. “By putting the e-charging infrastructure into operation, we are setting a milestone in the area of electric mobility and are affirming our pioneering role in environmental and climate protection. more
