Energy storage technology is a critical component in modernizing and transforming Europe's energy system. To rectify the strategic position of energy storage within the energy ecosystem and stimulate the sustainable and healthy development of the energy storage industry, the European Union and various European governments have formulated a series of policy measures, creating a more favorable environment for the development of the energy storage industry from all aspects.

Precise Control of Electricity Price Management Policies

To address the risk of energy supply shortages, maintain market supply and demand balance, and rationalize the electricity price formation mechanism, reforming the European electricity market is a top priority. In response to the recent shortage of traditional energy sources and soaring electricity prices, the EU has adopted multiple temporary control measures, such as setting a market revenue cap and levying an energy windfall tax, to curb disorderly market fluctuations and mitigate the impact of rising prices on people's livelihoods. These temporary control policies may have a certain impact on the profitability of energy storage projects in the short term. However, in the long run, they will further reduce the proportion of fossil fuels in electricity supply, forcing Europe to accelerate its transition to clean energy and creating demand for large-scale energy storage technology deployment. At the same time, these measures will compel Europe to address the root cause of electricity price fluctuations fundamentally. The large-scale integration of renewable energy will drive more households to install residential energy storage systems for self-consumption, freeing them from the impact of electricity price volatility.

Coordinating Overall Energy Storage Development Planning

To clarify the development road map for renewable energy in the energy structure, the EU has formulated a series of strategic plans, including the "Fit for 55% Emission Reduction Target" and the "REPowerEU Plan", which set specific planning targets for energy storage capacity requirements. The EU requires that by 2030, the share of renewable energy generation should strive to reach 45%, and it has made a binding requirement that the rooftops of certain new residential and commercial buildings must install photovoltaic systems, reserving a vast market space for residential energy storage systems. This also accelerates the deep integration of energy storage with distributed photovoltaic, directly driving a significant increase in energy storage capacity demand.

In addition to overall planning, European countries have formulated specific energy storage capacity targets based on their respective development realities. For example, Greece has proposed a target of adding 15 GW of energy storage capacity by 2030, while Italy plans to build several large-scale energy storage projects in its southern regions and islands, injecting policy momentum to promote the leapfrog development of its domestic energy storage industry. The UK has removed the capacity cap for residential energy storage projects, enhancing households' autonomy in choosing to install energy storage systems.

Consolidating Domestic Industrial Chain Construction

Reducing external dependence and enhancing Europe's autonomous and controllable capabilities in the domestic battery industrial chain is a current priority. The European Battery Alliance and the European Commission have jointly released strategies such as the "Green Deal Industrial Plan" to systematically deploy the development of domestic battery production capabilities, independently meeting battery demand and promoting the innovation and upgrading of energy storage technologies. The plan is expected to create a battery market worth around one trillion euros for Europe, generating millions of job opportunities.

Meanwhile, the EU has also vigorously introduced the "Innovation Fund", the "Net-Zero Industry Act", the "European Critical Raw Materials Act", and other regulations and funding support to strengthen the supply base for energy storage raw materials, expand domestic manufacturing scale, catalyze industrial technological progress, and construct policy guarantees for the sustainable and high-quality development of the energy storage industry.

Fiscal and Tax Policies Incentivizing End-User Applications

To boost the enthusiasm for end-user energy storage applications, various EU countries have opened green channels for fiscal and tax incentives. Germany has exempted income tax on rooftop photovoltaic systems and value-added tax on residential photovoltaic and energy storage systems, significantly reducing the investment threshold for households. The UK has allocated funding to support pilot applications of advanced long-duration energy storage technologies in the residential sector, while Italy has implemented a tax credit policy for energy storage investments. These fiscal and tax incentives aim to reduce the operating costs for end-users adopting energy storage systems, enhancing the overall economic viability of energy storage systems and greatly boosting households' enthusiasm for residential energy storage installations.

Creating a Fair and Efficient Market Environment

To open up a broader arena for energy storage technologies in the electricity market, the rules of the European electricity market are continuously optimized and adjusted to remove obstacles and grant energy storage a higher participation status and flexibility. Germany has enacted legal amendments to clarify the legal status of energy storage systems, streamline registration processes, and grant energy storage systems greater market participation flexibility. The UK has removed the capacity cap for battery energy storage projects, improving deployment efficiency, and continuously enriching the range of services that energy storage can participate in within the electricity market.

Such policy adjustments create a more fair and orderly market environment for energy storage projects, eliminating barriers, facilitating supply and demand, opening up new profit growth points, and enhancing the important role of energy storage technologies in power grid operations, ancillary services, and balancing, enabling them to compete on an equal footing with traditional energy sources.

Overall, the development policies for the European energy storage industry have formed a multi-level and comprehensive policy system spanning various segments of the upstream and downstream industrial chains, covering areas such as planning, power sector reform, fiscal and tax incentives, and market regulations. Under the guidance of these favorable policies, residential energy storage, as an essential complementary facility, will have an increasingly broad development prospect in Europe. Energy storage technology is ushering in an unprecedented strategic opportunity period, and its important position and role in Europe's energy system are becoming increasingly prominent, poised to become an accelerator and stabilizer driving the energy transition.
