The European renewables market is driving the battery storage boom

The battery storage capacity in Europe is expected to increase five-fold between now and 2030. This will bring increased returns for energy companies, traders, and project developers, as new projects become cheaper.

The use of wind and solar energy has increased to around a third in Europe's mix. However, because they are intermittent sources, there is also a demand for backup batteries.

Battery technology has also made great strides. Smaller battery packs can store more power and lower costs.

According to estimates from the industry, even the anticipated leap in capacity will not be enough to meet national demand and balance energy grids.

Aurora Energy Research predicts that capacity will rise to more than 50 gigawatts by 2030, which represents investments worth approximately 80 billion euros (82.80 billion dollars).

The European Association for Storage of Energy estimates that 200 GW of storage will be required by 2030.

According to Aurora Energy Research, a total of 10.8 GW in Europe's battery capacity has already been added by 2024.

Some investors have been disappointed by the renewable energy industry in general. In Europe, wind turbine manufacturers have seen their profits eroded by technical issues, supply-chain problems, rising costs, and planning disputes.

After the oil price recovery, following a slump in demand caused by pandemic locksdowns, energy majors are also under pressure from shareholders to focus on fossil fuels.

Battery storage is a great way to earn money.

Project operators can secure what is known as ancillary contract from grid operators who pay them for helping to balance the system. For example, capacity market contracts pay generators and battery owners for being available during times of high demand.

Price volatility on the wholesale energy market offers traders the opportunity to make a lot of money.

When the amount of wind or solar energy produced exceeds the demand on the grid, the electricity price can go negative. Battery operators are paid to store power in case it is needed.

The traders can make money if they can charge their battery at a low price because the prices are negative, and then sell it at a higher price at sunset at six o'clock. This is what Roberto Jimenez said, the executive director of BW ESS. BW Group, whose global infrastructure company includes BW ESS.

LSEG data shows that the number of hours with a price below zero or at a negative value in Britain's electricity day-ahead market reached a record 176 in 2024. It predicts a nearly four-fold rise to 792 hours by 2026.

Similarities are seen across Europe. LSEG predicts that the number of German negative hour will increase from less than 500 in 2024 to over 900 in 2026.

MAJOR PROFITS

BW ESS and oil giant Shell have an agreement for the 331 MW capacity of a battery project in Britain. Shell will pay a fee of fixed amount to BW ESS for the battery to be available to Shell when it sees a business opportunity.

TotalEnergies, another major, bought German battery storage firm Kyon Energy in the last year. The first project, a 200-megawatt-hour project, will begin operating in 2026 with an investment of 75 million euros.

TotalEnergies spokesperson said that the German market is interconnected with 11 other countries. This provides ample opportunity for trans-border electricity trade.

In order to attract investment, new markets will also offer initial revenues that are contracted. Italy's grid operator Terna announced that it will conduct a first auction for battery storage capacity before the end of 2025. The projects are expected to become operational by 2028.

Statkraft is Europe's biggest renewable generator. It has a portfolio of large batteries, including projects in Britain and Ireland. It has said that it will bid in the Italian auction.

RETURNS ARE RISING, COSTS ARE DRIVING DOWN

RBC analyst Joseph Pepper stated that the growing revenue from contracts and trade has pushed UK batteries revenues to their highest levels in two years. They are now at approximately 90,000 pounds ($112,617) each MW per annum.

The price of battery storage has also decreased due to the oversupply of batteries from China, and the shrinking size of the battery packs as a result of technological improvements.

Pepper said that the cost to build a project in Britain had fallen by around 30% over two years, and is now just a little above 500,000 pounds for a 2-hour project.

He said that the result of a British project will be returns in the range of 12%.

The main driver (to improve returns )...) is the large decrease and reduction of CAPEX for Batteries, said Tom Vernon. Statera Energy has over 1 GW in pipeline projects that are in operation or under construction in Britain.

This trend is likely to continue. Goldman Sachs analysts said that average battery prices could drop to $80/kWh in 2026 from $153 per Kilowatt-hour in 2022. ($1 = 0.9662 euros) ($1 = 0.7992 pounds)
