Battery storage: The energy plant within the basement is additional expanded | EUROtoday

Bastian Pfarrherr stands subsequent to a crimson metallic field that appears like a primary help container that’s too giant. However, it’s a electrical energy reminiscence at a parking house on the corporate premises of the town community operator Hamburger EnergieSetze. “Our electricity storage here serves exclusively to support the charging stations for the electric vehicles of our employees and guests,” says Pfarrherr, head of the innovation administration division at Hamburg Energy Act.

The firm operates the city electrical energy and pure fuel community. The reminiscence within the parking zone will not be related to the publicly accessible community, “because we, as a company regulated by the Federal Network Agency, are not allowed to operate memory with access to the electricity market,” says Pastor. The system he exhibits shops 70 kilowatt hours. “This corresponds to the drive battery of an upper middle class vehicle with an electric drive,” he says. The variety of such battery storage has risen drastically in Hamburg lately: “Nowadays, a high four -digit number of battery stores in private households has been in operation in Hamburg,” says Pfarrherr. “All together have a total output of 80 megawatt hours. This could cover the Hamburg electricity needs for about three minutes.”

However, that is solely a calculation dimension. With the smaller battery storage, the main target will not be on the “swarm suitability”, the synchronized mixture of hundreds, however above all the advantages for personal or business homeowners. Many householders now set up battery storage to save lots of solar energy from the roof system as a way to implement a business benefit and make a contribution to local weather safety.

The significance of such battery storage in personal or small -scale utility will most likely enhance sharply within the coming years: “Vattenfall sees great potential for the energy transition in your own home – and therefore also battery memory as an important component, especially in combination with photovoltaic systems, heat pumps or wall boxes for the electric car,” says the corporate on request. Vattenfall is the market chief within the energy provide of personal households in Hamburg. “We are already installing a battery memory in more than 90 percent of our photovoltaic customers.”

And the interactive abilities of battery storage in households are expanded by regulation. With the introduction of the paragraph 14a of the Energy Industry Act, all newly put in battery storage must be “registered as controllable consumption units with the community operator since January 1, 2024, mentioned Vattenfall. “In return for registration as a controllable consumption device under a household meter, the legislator has provided a flat -rate remuneration of the network use fees.” From April 1, a electrical energy buyer and reminiscence operator can “then choose time -variable network charges. Customers can continue to optimize a shift in electricity consumption and also from battery charges at times with low network charges.”

The mandatory measurement and billing units required, personal households with their battery storage can now act in an identical approach to operators of economic storage systems- you possibly can both use electrical energy or promote it costlier, additionally with the assistance of latest tariffs: “Energy administration apps have gotten extra vital if you will need to do the clever interplay of family home equipment, warmth pumps, photovoltaic programs, battery shops Or E-car in addition to dynamic tariffs and consumption.

Large battery shops, then again, don’t seem appropriate for the development and use within the metropolis for the foreseeable future. The city operator of Hamburg’s power community already has inquiries for this, however the probabilities of realizing such initiatives are most likely low. “We currently have around 20 inquiries for the construction of large battery stores with access to the Hamburg power grid, which includes a total output of 2000 megawatt – two gigawatts -” says Bastian Pfarrherr. “However, we do not have enough space in Hamburg to build large battery stores. These memory release a lot of warmth, they cannot be built up.” A reminiscence with 200 megawatts of electrical energy energy would want the realm of ​​a soccer discipline, he says. And not solely on treasured areas for soccer fields in Hamburg, however above all for flats and for homes.
