Investment Opportunities in the Green Energy Wave: How Energy Storage and Power Saving Concept Stocks Drive the transition?

A major transition in the energy structure is underway. As global climate policies tighten, electric vehicle penetration increases, and renewable energy (wind, solar) installed capacity rapidly grows, energy storage has become the hub of the new energy industry. This not only drives the popularity of energy storage concept stocks but also generates related investment opportunities such as power-saving concept stocks. This article will analyze the investment logic of the energy storage industry chain in depth and outline noteworthy Taiwan and US stock targets.

Global Net-Zero Goals Drive Energy Storage Demand

A report from the United Nations Climate Organization states that to limit global warming to 1.5°C, countries must halve carbon emissions by 2030 and achieve net-zero carbon emissions by 2050. Under this consensus, government investments have increased significantly, and technologies previously costly, such as wind and solar, have become commercially viable.

However, the intermittency of new energy generation has emerged as a challenge. For example, in the UK, wind power contributed 32.4% of electricity supply in the first half of 2023 but experienced negative electricity prices during low-demand periods. Such volatility is precisely where energy storage technologies can demonstrate their value. According to BloombergNEF and DNV forecasts, the global cumulative energy storage demand will surpass the terawatt-hour (TWh) mark by 2030, with lithium-ion batteries dominating.

Multi-Dimensional Investment Opportunities in the Energy Storage Industry Chain

The scope of energy storage concept stocks is broad, spanning the entire industry ecosystem. Investors can approach through the following four segments:

Battery Manufacturers are the core link. The shipment volumes of lithium batteries, solid-state batteries, sodium-ion batteries, and other technologies will directly benefit from demand growth. Challenges include raw material fluctuations and international competition. Taiwan’s Xinshengli (4931), Changyuan Technology (8038) are representative companies.

System Integrators add value by coordinating overall solutions. They not only supply batteries but also integrate inverters, battery management systems, and energy management systems to deliver complete solutions. Hwa Sheng (1519), A-Li (1514), and Chung Hsing Electric (1513) are major Taiwanese players.

Power Infrastructure involves connecting energy storage systems to the grid, including transformers, distribution panels, and other equipment suppliers, also covered by companies like Hwa Sheng and A-Li.

Upstream Supply Chain includes cathode materials (nickel, cobalt, lithium iron phosphate, etc.), electrolytes, separators, and other key raw materials, as well as downstream battery management and cooling systems. Formosa Plastics (6505) holds a significant position in electrolytes.

Power-saving concept stocks approach from another angle—reducing energy storage demand by optimizing energy efficiency. These companies are also worth investor attention.

Q2 revenue of $363 million exceeded expectations, but Q3 guidance was weak ($330–370 million), reflecting short-term demand pressure. The risk of the US residential solar subsidy ending at year’s end is considered a major challenge by brokers. TD Cowen has downgraded to Hold with a target price of $45–$55.

Generac Holdings (GNRC) focuses on backup power equipment. Q2 adjusted EPS was $1.65, up 22% quarter-over-quarter, with revenue of $1.06 billion also beating expectations. Market expectations for 2025 full-year EPS are $7.54, with a target price of $206.67 compared to the current $179.50, leaving about 15% upside.

NextEra Energy (NEE) is the world’s largest utility company. Its subsidiaries Florida Power & Light and NextEra Energy Resources cover traditional and green energy businesses. In 2024, revenue is projected at $24.75 billion, with a total generation capacity of 73 GW. Q2 adjusted EPS was $1.05, up 9% year-over-year; it added 3.2 GW of renewable and energy storage projects, with a planned capacity exceeding 10.5 GW, leading in AI data center energy demand. The target price is approximately $84–$86, about 15–20% higher than the current $72.65.

Fluence Energy (FLNC) is a leading global provider of energy storage products, jointly launched by Siemens and AES in 2018. Q3 EPS was $0.01, in line with expectations, but revenue of $603 million was far below the expected $770 million, causing a stock decline of over 13%. Delays in capacity expansion and supply chain challenges in the US led to shipment postponements, but the company maintains its 2025 revenue target of $2.7 billion.

EnerSys (ENS) specializes in industrial energy storage solutions, headquartered in the US, with operations in over 100 countries. Q1 performance was strong: adjusted EPS of $2.08 and revenue of $893 million, both exceeding expectations. With a market cap of $3.86 billion, P/E ratio of 11.8, and a dividend yield close to 1%, it is attractive to conservative investors.

Leading Taiwanese Energy Storage Stocks Perform Strongly

Delta Electronics (2308) is a global leader in exchange-type batteries. Q2 consolidated revenue reached NT$124.035 billion (up 20% YoY, a new quarterly high), net profit after tax NT$13.948 billion (up 40%), and EPS of NT$5.37, also a record high. Gross margin is 35.5%, operating margin 15.1%, significantly better than previous periods. The company will strengthen R&D and expand US capacity in the second half, with continued growth momentum expected.
