Jannik Carl, from Kraken Technologies under Octopus Energy Group, elaborates on the significance and financial prospects of Battery Energy Storage Systems (BESS) in contemporary energy frameworks. BESS is pivotal for incorporating renewable energies into power grids by ensuring stability as traditional generators are phased out. The rise of renewables like solar and wind has reduced costs compared to conventional sources but introduces challenges such as curtailment due to their intermittent nature. Batteries provide rapid response times essential for system balance amidst these changes. Carl notes shifts in both supply and demand: household solar reduces daytime demand while electrification increases peak demands through heat pumps and EVs, leading to unpredictable consumption patterns globally. Financially, BESS can leverage ancillary services or balancing markets alongside day-ahead trading—buying low-cost energy to sell during high-demand periods—to generate revenue despite market saturation risks from increased battery deployment. The discussion also covers complexities in European battery trading focusing on ancillary services and arbitrage opportunities amid rising renewable penetration causing market volatility—a scenario ideal for profitable arbitrage strategies requiring technical expertise supported by robust software solutions like Kraken's platform that optimizes asset management across utility-scale operations or behind-the-meter setups efficiently managing operational intricacies crucial as individual assets encounter similar challenges previously observed in British markets.

Jannik Carl
The utility-scale BESS market in Germany has experienced significant growth in the last two years. Typical project size has increased by an order of magnitude over that timeframe from 20 MW to 200 MW. The number of developers in this sector has increased at a comparable rate. But how can developers make key decisions around project design when they are often not the long-term asset owners? How integrated are developers with investors during the project design phase, and what could be done more effectively? In this panel, major players from the investor and developer communities will discuss project design, commercial models including the rise of contracted off-take agreements and expected returns in this fast-growing market.
