Rolls Royce Power Systems and batteries, a combination that is being consolidated. The company’s investments, starting with the acquisition of Quinos, and its pioneering spirit in the smart grid, suggest that the road is clear. Today we’re going to tell you a couple of stories. The first one is from the German State of Niedersachsen, where “An mtu EnergyPack from Rolls-Royce is at the center of a field test begin carried out with the aim of supplying power sustainably and as far as possible, independently of the public utility grid. The project name is ‘energy platform Twistringen’ and in it grid operator Avacon is simulating the operation of local grids by energy communities independently of the public grid. Part of the project involves the delivery by Rolls-Royce to Avacon Netz GmbH of a 20-ft mtubattery container with 1,000 kWh capacity and 800 kVA output. The growing demand for electrical power and the call for climate-neutral, efficient power generation represent a challenge to grid operators like Avacon. New solutions need to be developed and one of them could be the formation of local energy communities’ who obtain their electrical power from wind turbines, solar panels and electrical generator sets. In the current pilot project, Avacon is examining how such an energy community could generate, store and consume electrical power. The main job of the mtu EnergyPack will be to bridge the gap between the supply of green energy, which tends to fluctuate, and the power needs of households and businesses within the local grid. The project is supported by PlatOne (PLATform for Operation of distribution Networks), a consortium of energy grid partners funded by the EU.”
EnergyPack battery in Norway
The second case study is from Scandinavia. “Norwegian utility company Arva is to use three Rolls-Royce mtu EnergyPack battery energy storage systems to investigate how a public power grid can be stabilized using electricity stored in batteries. Rolls-Royce is supplying three mtu EnergyPacks QL with an output of 4.25 MVA and 3.79 MWh of capacity to the Norwegian island of Senja. They will be used to iron out voltage fluctuations in the towns of Husøy and Senjahopen which are dominated by the power-hungry fishing industry. Rolls-Royce will be involved in the research project for five years and is to provide maintenance for ten years under a long-term service agreement (ValueCare Agreement). Senja, a few hundred kilometers north of the Arctic Circle, has a highly industrialized fish processing industry. Its modern production facilities require reliable power supplies which the grid is currently unable to provide due to the town’s location on the outside periphery of Arva’s supply area. This not only results in temporary production losses, but also prevent further expansion of the fishing industry.
This is why Arva has ordered three top-of-the-range mtu EnergyPacks QL from Rolls-Royce. Two of these battery containers will be installed in Husøy, and one in Senjahopen, and will be hooked up to the supply grid. From autumn onwards, they will act as buffer storage units to solve quality problems in the power supply and compensate for fluctuations in the grid. They can supply local businesses and private households with electricity for up to one hour at a time in the event of a power failure, or be used to compensate for additional electricity demand. Modern power management systems in companies and private households are to be integrated, as are local solar power systems. The findings from the research project are to be used to help improve security of supply across the entire Arva grid.
