Danish offshore wind energy giant \u00d8rsted is currently well into constructing what will be the world\u2019s largest offshore wind farm, the 2.9-gigawatt (GW) Hornsea 3 project, which will also be the first project in the world to feature a utility-scale battery integrated directly into an offshore wind farm\u2019s transmission infrastructure.<\/p>\n

\u00d8rsted began installing the foundations for the wind farm earlier this year, with the first mammoth monopile being sunk into the seabed in May<\/a>. The wind farm, which will feature 197 wind turbines and is expected to be completed by the end of 2027, will generate power equivalent to the needs of 3.3 million UK homes.<\/p>\n

In addition to the massive number of wind turbines, Hornsea 3 is also adding a two-hour 300-megawatt (MW), or 600 megawatt-hours (MWh) battery energy storage system.<\/p>\n

Construction of the Iceni\u00a0battery energy storage system (BESS) \u2013 named for the Norfolk-based warrior tribe of the Roman era \u2013 began in March<\/a> and is expected to be operational sometime in the first quarter of 2027.<\/p>\n

Iceni will feature Tesla batteries and be capable of storing power equivalent to the daily consumption of 80,000 UK homes. <\/p>\n

It is also the world\u2019s first utility-scale battery system to be directly integrated into an offshore wind farm\u2019s transmission infrastructure. Iceni will be built on the same land as the onshore converter station, and instead of boasting its own standalone grid connection will share transmission assets and an onshore grid connection with Hornsea 3.<\/p>\n

The 300 MW\/600 MWh Iceni BESS will also utilise the Nimbus optimisation, asset management, and trading platform designed by London based renewable energy services firm Arenko.<\/p>\n

Under an agreement signed this week, Arenko\u2019s will deploy its full Nimbus platform to manage trading, optimisation, and asset management of Iceni.<\/p>\n

\u201cIceni is a highly sophisticated project, coupling a grid scale battery with one of the UK\u2019s biggest offshore wind farms,\u201d said Rupert Newland<\/a>, CEO of Arenko<\/p>\n

\u201cThis creates significant opportunities, but also operational and trading challenges, from forecasting and deciding how and when to allocate capacity in real time, to the technical, data and controls integrations between the two assets.<\/p>\n

\u201cWe\u2019ve worked closely with \u00d8rsted over time as their thinking around flexibility has evolved, and with projects like Iceni they are taking a pioneering role in bringing truly significant generation capacity and utility-scale storage together.<\/p>\n

\u201cNimbus is built for that kind of environment, providing the automation and optimisation capabilities needed to manage increasingly large and complex assets, across multiple markets.\u201d<\/p>\n
