How Businesses can Turn Cost Pressure into New Revenue with Behind-The-Meter Energy Storage

Taipei, June 24, 2026 – As AI data centers, high-performance computing (HPC), advanced semiconductor manufacturing processes, and AI supply chain production continue to expand, Taiwan is facing a new wave of electricity consumption growth pressure.

Taipower estimates that total new electricity demand across Taiwan will surge 2.5 times over the next five years. At the same time, the Executive Yuan has recently passed a partial amendment to the Energy Management Act, mandating that large electricity consumers with contracted capacity above a certain threshold must install self-generation and energy storage equipment within a specified deadline. Coupled with Taiwan’s carbon fee officially entering the substantive payment phase this year, large electricity consumers are now confronting a new set of simultaneous challenges: rising electricity costs, power supply stability, and increasing pressure to reduce carbon emissions.

Enel X, a global leader in Virtual Power Plants (VPP) and Demand Response, noted that the industries affected by this amendment span semiconductors, electronics manufacturing, AI data centers, metalworking, chemicals, and large commercial venues that are among high electricity consumption sectors. Particularly in the AI era, businesses are no longer facing merely rising electricity prices, but the challenge of building resilient, autonomous energy dispatch capabilities, shifting the energy management mindset from “energy saving” to “energy asset management.”

Enel X stated that, given installation costs that often start in the millions, energy storage systems should not be regarded solely as a regulatory compliance expenditure. In fact, through professional management of “behind-the-meter battery energy storage systems (BTM BESS)” and “demand response”, businesses not only can reduce electricity bills, meet regulatory requirements, and avoid penalties, they can also shift from a passive to a proactive stance, transforming energy storage equipment into a financial management tool and creating an entirely new revenue stream for the business.

The growing penetration of renewable energy is transforming the electricity system. The variability of solar and wind energy increases the importance of flexible energy resources that can respond quickly to changing grid conditions. For example, during evening periods when solar generation declines rapidly, fast-responding distributed energy resources are needed to help maintain grid stability.

The International Energy Agency (IEA), in its Electricity 2026 report, highlights that global energy management is shifting to demand flexibility management. Businesses are no longer mere electricity consumers, they must develop the ability to respond dynamically to changes in the power system. BTM BESS is one of the most effective technologies available to support this transition.

Enel X pointed out that BTM BESS can help major energy consumers meet mandatory requirements while also providing backup power and unlocking additional value. Depending on a company’s scale and energy profile, one or more of the following benefits may be achieved, and in many cases, stacked simultaneously:

• Time-of-Use (TOU) Arbitrage: One of the most common applications of energy storage is charging during lower-cost off-peak periods and discharging during higher-cost peak periods. Under Taiwan’s current three-tier TOU pricing structure, the average price difference is approximately NT$4.7 per kWh, creating meaningful opportunities for cost optimization.
• Demand Charge Management: By discharging the BESS during peak demand periods, businesses can suppress partial peak demand, reducing their draw on the grid. This can lower contracted capacity, avoid penalties for exceeding the contracted limit, and reduce electricity costs.
• Participating in Ancillary Services on the Energy Trading Platform to profit: The key to monetizing energy assets. By joining a Virtual Power Plant (VPP) such as Enel X’s, the BESS can respond when the grid needs support, helping to maintain grid stability while generating additional revenue.
• Supporting 24/7 Renewable Energy Balance: For businesses with renewable energy procurement needs tied to international supply chains (such as RE100 or CBAM), BESS can help reduce wasted surplus power, and significantly improve procurement efficiency.

Enel manages over 10 GW of flexible energy resources globally. To help Taiwanese businesses maximize the economic value of BESS, Enel X has been actively bringing its globally leading VPP and demand response aggregation expertise to Taiwan since 2016. The company is now looking to introduce BESS optimization through an all-in-one integrated platform, helping businesses automatically evaluate factors such as electricity tariffs, contracted capacity, battery lifespan, and system safety constraints to determine the optimal charge and discharge strategies. This allows businesses to participate in complex energy market opportunities through a single integrated platform, without requiring additional operational resources.

For example, a business with a 1 MW/2 MWh BESS may be able to combine TOU arbitrage, contracted capacity management, and ancillary services to generate annual revenue exceeding tens of millions of New Taiwan dollars.

Enel X stressed that as the trend towards decentralized grids accelerates, maintaining grid stability no longer relies solely on large generation units, but increasingly depends on the active participation of distributed resources located on the demand side.

BTM BESS is more than a backup solution. It is a strategic investment that can help businesses strengthen operational resilience, optimize energy costs, and build a smarter, more flexible energy future. Contact us to learn how you can monetize your energy assets today.
