The global household savings cycle is here! Surging electricity prices + geopolitical conflicts catalyze a full-scale takeoff in Europe, the United States, and emerging markets.

Electricity prices are skyrocketing, subsidies are being rolled out intensively, and the structure of the essential-demand market is expanding. The global residential energy storage industry is now entering a new, protracted upswing cycle.

In a storage industry in-depth report published on the 31st, Guolian Minsheng Securities noted that in 2025, global residential energy storage system shipments were approximately 35GWh, up nearly 50% year over year, signaling that the industry—after going through an inventory adjustment—has entered a new demand-release cycle.

Looking ahead to 2026, geopolitical conflicts in Europe are driving up natural gas and electricity prices; Australia’s subsidy budget has been increased to 7.2 billion Australian dollars; ongoing U.S. power shortages are deepening; in emerging markets, electricity shortage essential demand is compounded by lower costs for PV plus storage. The four key core regions are expected to enter installation-related upswing cycles in sync.

The European market’s catalyst is the most direct. The conflict between the U.S. and Iran leads to a blockade of the Strait of Hormuz, causing Europe’s benchmark Dutch TTF natural gas price to double within a few weeks after the outbreak of the conflict, at one point exceeding 60 euros/MWh. As of March 23, 2026, the average day-ahead electricity spot prices in countries including Italy, Austria, Hungary, and Romania have already exceeded 150 euros/MWh, and Germany and the U.K. are also above 140 euros/MWh. Meanwhile, multi-country subsidies for residential storage in the U.K., Poland, Hungary, and others have been gradually rolled out. The further retreat of net metering policies and the普及of dynamic electricity pricing further improve the economics of residential storage.

Europe: Rapid surge in electricity prices + intensive subsidies; low-penetration markets are set for full-scale catalysts

The European residential storage market has a dual logic of both structural demand and policy catalysts, and the current sharp rise in energy prices is accelerating demand release.

On the supply-and-demand pattern level, in 2025 the share of wind and solar generation in the EU reached 30%, exceeding fossil fuels for the first time, but the time mismatch between wind/solar output and electricity load further increases pressure on grid absorption. In 2025, the duration of negative electricity prices in Spain, Germany, and the Netherlands exceeded 500 hours; Belgium, France, Poland, and others exceeded 450 hours. The smoothing role of energy storage is becoming increasingly evident.

Penetration is still at a low level, with substantial room for improvement. As of end-2024, Europe’s rooftop PV installed capacity was about 215GW. Compared with the potential installable capacity of 2340GW, penetration is only about 10%. Between 2022 and 2024, the average penetration rate of residential storage in residential PV in Europe was 20%. By country, in 2024, Germany and Italy’s incremental residential storage versus residential PV penetration rates reached 79% and 76%, respectively. The U.K., Austria, and Sweden were also between 29% and 54%, indicating that the activity level of new installations is clearly higher than penetration of existing stock.

On the economics level, three factors combine to systematically improve residential storage returns. First, the retreat of net metering is forcing self-consumption demand. The Netherlands plans to fully abolish the net metering system in 2027, while Germany will cancel fixed feed-in tariff subsidies for distributed PV systems below 25 kilowatts starting in 2027, which is expected to trigger a rush-install effect. Poland, France, Romania, Croatia, and others have also tightened net metering policies in succession. Second, the普及of dynamic electricity pricing opens up peak-valley arbitrage space. Since January 2025, Germany has been mandating smart meters and dynamic electricity pricing. According to data from German smart home company Tado°, in the first half of 2024, residential users adopting dynamic electricity pricing saved up to 34% on electricity bills compared with the wholesale average price. Third, the improvement of the virtual power plant (VPP) mechanism provides an additional channel for incremental earnings. The EU has explicitly clarified that aggregators may represent small distributed energy resources to participate in all electricity markets, including wholesale, balancing, and ancillary services. Countries including Germany, the U.K., France, and Italy have followed with supporting policy rollouts.

Subsidies are being pushed intensely. By the end of January 2026, the U.K. will launch the “Warm Home Plan,” planning to invest 15 billion pounds by 2030 to promote PV plus storage普及, with a target of 3 million households installing rooftop PV. Poland plans to implement a “residential energy storage subsidy” program with a total budget as high as 1 billion Polish zloty between 2026 and 2030, with subsidies covering 30% of eligible costs. Hungary has introduced residential storage subsidies with a total budget of 100 billion forints; the maximum per household can cover up to 80% of investment costs, with applications opening in February 2026. Germany has set up a climate transition fund of 100 billion euros (KTF). In Spain, among the 700 million euros aid programs approved by the EU, the subsidy proportion for user-side storage projects can reach 65%.

Overall, in 2025, the EU’s incremental installed capacity for residential storage was 9.8GWh, declining for two consecutive years. Looking ahead to 2026, with the combined effects of intensive subsidy rollouts, improvement of earnings models, and geopolitical conflicts driving up electricity prices, Europe’s residential storage installed capacity is expected to return to a high-growth trajectory. If the U.S.-Iran conflict continues for longer, European natural gas prices and electricity prices may rise further, bringing additional upward upside elasticity.

Australia: Severe shortfall in storage despite high PV penetration; subsidy effects significantly exceed expectations

Australia has a structural contradiction of high PV penetration but a severe mismatch in energy storage. After government subsidies were introduced, the market response was significantly beyond expectations.

As of end-2025, Australia’s rooftop PV installed capacity had reached 28.3GW, exceeding the total capacity of all domestic coal-fired power generation units of 22.5GW; more than 4.3 million households have completed installations, and penetration is 39%. The share of rooftop PV generation also rose from 7.2% in 2020 to 14.2%. However, as of end-2025, only 454,000 households had installed energy storage batteries, and residential storage penetration was only 10.6%, highlighting a pronounced mismatch.

The rapid expansion of renewable energy has led to increased intra-day electricity price volatility and more frequent negative electricity prices. In Q4 2025, the share of renewables in Australia’s energy mix first exceeded half; in all trading intervals in South Australia, 48.4% saw negative electricity prices. The widening peak-to-valley price spread and the frequent occurrence of negative prices create objective space for residential storage arbitrage, strengthening residents’ economic motivation to install energy storage systems.

Subsidy policies are activating potential demand. In July 2025, the Australian federal government launched a 2.3 billion Australian dollar “Home Battery Subsidy Program,” providing subsidies of up to 372 Australian dollars/kWh for energy storage batteries with capacity from 5 to 50kWh, roughly covering 30% of installation costs. According to data from the Clean Energy Council of Australia, in the second half of 2025, incremental installed capacity for residential storage reached 183,000 sets, up 305% year over year, and for the full year incremental installations were 269,000 sets. In December 2025, the Australian government increased the subsidy budget to 7.2 billion Australian dollars and introduced a capacity-tier subsidy mechanism, targeting 40GWh of incremental energy storage capacity by 2030. Guolian Minsheng Securities expects that in 2026, Australia’s residential storage demand is likely to continue growing rapidly.

U.S.: Ongoing deepening of power shortages; TPO model and VPP jointly underpin medium- to long-term installations

After experiencing policy shocks in 2025, the U.S. residential storage market is expected to maintain a high level of demand support in the medium and long term, backed by both persistent power shortages and new business models.

In 2025, the “Big Beautiful” bill removed a 30% tax credit for residential PV and storage projects, triggering large-scale rush installations. According to Wood Mackenzie data, in 2025, incremental installed capacity for new U.S. residential energy storage was 2.685GW/3.318GWh, with both power and capacity increasing by 92% and 39% year over year, respectively. Looking ahead to 2026, under the third-party ownership (TPO) model, residential systems are commercial projects and can continue to enjoy tax credits. Users will use the systems through lease or power purchase agreements, or it may become a substitute for owning PV plus storage systems, providing continuity support for the market after policy exits.

Power shortages are a deeper structural driving force. The surge in AI data centers combined with the wave of retirement of traditional power sources keeps widening the power supply-demand gap. According to a Rand estimate, by 2030, the power demand driven by AI data centers is expected to reach 158 to 253GW, while the net available capacity increase in the U.S. front-end power grid will be only about 33GW. The supply-demand imbalance has already appeared in the price signal: in 2025, the average U.S. residential electricity price rose 5% year over year to 17.30 cents/kWh; in January 2026, it rose another 9.5% year over year. Increases in Virginia and Florida were 13.8% and 10.4%, respectively. In February 2026, a strong winter storm left more than 500,000 users without power, again exposing grid fragility.

The VPP mechanism is becoming increasingly mature, further expanding the sources of residential storage earnings. Currently, in about half of U.S. states, owners of residential storage batteries have the opportunity to join virtual power plants, provide grid services, and receive compensation. The U.S. Department of Energy plans to increase VPP installed capacity to 80 to 160GW by 2030 to meet peak-load demand needs of 10% to 20% nationwide. Wood Mackenzie predicts that from 2026 to 2031, U.S. residential storage installed capacity still has the potential to remain at a high level.

Emerging markets: Essential demand driven by power shortages combined with falling costs; off-grid potential not yet fully released

Residential storage demand in emerging markets has a distinct essential-demand attribute, and as PV plus storage system costs continue to fall, latent purchasing power is being unlocked.

Regions including India, Pakistan, Southeast Asia, and Africa face long-term instability in power supply due to fuel shortages, weak generation capacity, and aging grids, leading to frequent blackouts and electricity price hikes. As PV plus storage system costs decline, more households will have the ability to install. Residential PV plus storage not only can guarantee power supply during outages, but also can reduce overall electricity costs through self-generation and self-consumption, providing sustained support for a period of high demand optimism.

Geopolitical conflicts in the Middle East also constitute a catalyst. In regions such as Iraq, Israel, and Lebanon, instability is causing frequent electricity shortages and outages, highlighting residential storage’s essential-demand profile. The U.S.-Iran conflict may further tighten power supply conditions in the Middle East. Combined with post-disaster reconstruction needs, it may spur faster rollout and scaling of residential storage installations in the region.
