Battery Storage as a Strategic Asset for Municipal Utilities
Many municipal utilities face major challenges in a changing energy market. The energy transition requires the expansion of renewable energy, the integration of decentralized and intermittent generators and consumers, the digitization of grids, and the creation of flexibility options. At the same time, competitive pressure is increasing due to new market entrants, declining margins in traditional business areas, and high investment costs.
In recent years, the electricity market has become increasingly volatile due to the expansion of renewable energy. This leads to extreme price fluctuations and presents new challenges for municipal utilities. Battery storage could be a solution to this problem. But are batteries really the new power plants for municipal utilities?
Focus on Flexibility and Cost-Effectiveness
Batteries have the potential to play an important role for municipal utilities, especially when it comes to shifting the timing of energy supply and managing peak loads. Unlike conventional large-scale power plants, which are often not flexible enough to respond quickly to changes in the power grid, batteries can rapidly store and release energy to stabilize the grid. Another advantage of batteries is their ability to take advantage of price fluctuations. When electricity prices fall, batteries can store energy at a low price and sell it later when prices rise again due to increasing electricity demand. This can help increase the profitability of municipal utilities and offer end customers an attractive dynamic electricity rate while simultaneously stabilizing the grid and reducing the load on it.
Another opportunity for municipal utilities to benefit from batteries arises from the mandatory introduction of dynamic electricity rates starting in 2025 for electricity providers with more than 100,000 customers. These rates—or rather, their pricing components—vary depending on supply and demand in the electricity market. This gives end customers an incentive to adjust their consumption to the market situation and use energy when it is inexpensive due to an oversupply. This can lead to better utilization of the existing grid infrastructure and reduce the need for expensive grid expansions. Dynamic electricity rates could also increase the adoption of electric vehicles and smart home devices, which offer additional flexibility options. For municipal utilities, offering flexible rates can also lead to greater customer loyalty, as customers engage more deeply with the topic of energy and their consumption habits.
Expanding battery storage or making demand more flexible?
Municipal utilities face a question when considering a potential investment in new battery storage: Which will happen faster—the expansion of battery storage or the increased flexibility of demand? Batteries have an advantage here, as they compete with efforts to increase demand flexibility. The 7,000-hour rule still requires the industry to consume power as evenly as possible and avoid power spikes. This means that battery investors will enjoy a favorable and profitable period in the coming years.
Intelligent marketing can replace a power plant
The design of a battery depends on its application. Factors such as capacity, power, and cycle life play a role. Intelligent allocation across different markets—such as the balancing energy market and the wholesale market—can significantly increase a battery’s value and thus optimize energy costs for municipal utilities. The question, therefore, is no longer whether to market balancing energy or trade on the intraday market; rather, a smart combination of both marketing approaches leads to the highest possible returns.
Here, ESFORIN can serve as an experienced and independent partner for municipal utilities, offering an innovative Cross-market marketing strategy for battery storage systems offers. ESFORIN has been active in the short-term trading markets since 2015 and therefore has extensive experience, which it applies today in the marketing of batteries. –Through the continuous and dynamic optimization of battery storage systems in various markets, including intraday trading, ESFORIN can leverage the volatility of the electricity market as an opportunity and maximize the return on battery storage systems for municipal utilities. In doing so, ESFORIN takes into account the individual conditions and restrictions of each municipal utility and offers transparent and fair billing.
In summary, batteries have the potential to play an important role for municipal utilities. They offer flexibility, can take advantage of price fluctuations, and help stabilize the power grid. With their enormous flexibility, battery storage systems can help make the electricity mix even greener and align it with renewable generation, thereby contributing to an energy system that is both green and secure!
