Commercial Users Seize Electricity Price Arbitrage Opportunities: Billion Watts’ Behind-the-Meter Energy Storage Enhances Competitiveness

2024 Nov 21

The user-side energy storage site in Eastern Taiwan showcases neatly arranged Billion Watts' commercial and industrial energy storage systems.

As the demand for commercial and industrial (C&I) electricity continues to rise, businesses are facing dual pressures of insufficient power supply and increasing electricity rates. According to data from Taiwan's Bureau of Energy, electricity demand is projected to grow at an annual rate of 2.03% from 2023 to 2029, with peak load growth reaching 2.04%. This trend is particularly prominent in the semiconductor and electronics manufacturing industries. Additionally, high-voltage users face a peak-to-off-peak electricity price difference of up to TWD 7 per kWh, with some high-energy-consuming industries experiencing electricity rate hikes of up to 14%, further challenging operational costs. In response, Billion Watts Green Energy, a subsidiary of Billion Group (Stock Code: 3027), offers diversified solar-plus-storage solutions to help enterprises address electricity price pressures. By leveraging price arbitrage models and peak-to-off-peak load-shifting strategies, Billion Watts enables businesses to enhance energy efficiency, promote sustainability, and achieve win-win outcomes.

Taiwan’s Power Supply and Demand Challenges: Solutions in Sight

In Taiwan, where land is scarce and densely populated, distributed energy systems and demand management are critical to addressing energy allocation challenges. The rising electricity demand driven by science parks, AI computing data centers, and industrial upgrades has highlighted a growing imbalance between regional supply and demand. For example, the southern high-tech industrial zone is increasingly reliant on stable power while grappling with tight supply. Delayed progress in natural gas and renewable energy projects further exacerbates the strain.

Amid difficulties in expanding power generation ("Developing new sources"), Taiwan urgently needs to explore "energy conservation" strategies to optimize existing resources and mitigate supply-demand imbalances. Investing in behind-the-meter energy storage systems provides enterprises with practical solutions such as virtual power plants (VPPs) to balance electricity supply and demand. These systems can be dispatched by utilities during peak hours or shortages, playing a crucial role in grid stability. By aggregating resources such as microgrids, load adjustments, electric vehicles, and behind-the-meter solar-plus-storage systems, energy storage systems can store surplus power and release it during peak periods, reducing both power loads and costs.


Billion Watts offers innovative cooperation models, including profit-sharing energy savings plans, enabling businesses to adopt behind-the-meter energy storage systems at minimal cost. These models promise annual returns of 10% to 20%, helping enterprises achieve a balance between electricity price arbitrage and energy conservation.

Diversified Green Energy Applications and Business Models Help Enterprises Tackle Rising Electricity Costs

Billion Watts, one of the few energy companies deeply integrating solar, storage, and monitoring technologies, leverages the resources of the Billion Group to offer locally manufactured green energy products and customized battery systems. This ensures stringent quality control standards. The Billion Group’s proprietary brand, Billion, offers a wide range of green energy products, including photovoltaic inverters, energy storage systems, and EV charging stations. Among these, the Fusio One 100kW/215kWh Commercial & Industrial All-in-One Energy Storage System features modular design for ease of installation and operation, coupled with advanced energy management technology, making it an ideal choice for businesses facing high electricity prices and market volatility.


Billion Watts addresses market demands with innovative technologies and exceptional services, highlighting the pivotal role of energy storage technology in energy transitions. To date, Billion Watts has serviced over 1,500 solar power plants with a total monitored capacity of 550 MW and completed the installation and grid connection of over 350 MW of solar inverters. Notably, Billion Watts has developed Taiwan’s first large-scale energy storage site in the Yunlin-Chiayi region, a 64MW/262.43MWh E-dReg project. Expected to begin operation in the first quarter of next year, the site will provide energy transfer and dynamic regulation services for grid frequency stabilization. This achievement not only demonstrates Billion Watts’ technical leadership in Taiwan’s energy storage market but also underscores its active contribution to energy system stability.

Successful completion of Yunlin 64MW/262.43MWh E-dReg project, ready to Join Taipower’s energy trading platform next year.

Billion Watts continues to expand its market influence by actively venturing into behind-the-meter markets and establishing virtual power plants. Recently, the company completed multiple behind-the-meter energy storage installations for major power users. By the end of the first quarter of 2025, it plans to deploy 2.6 MW of behind-the-meter energy storage resources, joining real-time reserve bidding and energy price arbitrage operations.



Global expansion efforts in the energy storage market have also yielded significant results. Collaborating with partners, Billion Watts has recently developed several solar-storage microgrid projects in Palau, Tuvalu, and the Marshall Islands, with a total capacity of 350kW/1978kWh, providing a model solution to address power shortages in Pacific Island nations. Meanwhile, Billion Watts is actively targeting other high-potential markets, focusing on Japan's JEPX and Australia’s NEM power trading markets since the third quarter of this year. The company aims to complete 20 MW of grid-connected energy storage and solar-storage projects by next year.

近期新北市發生疑似因「消費性應用鋰電池」充電意外引起的火災事故,導致有部分民眾因近期建置中的雲林斗六儲能案場使用的鋰電池擔心是否有安全的疑慮,本公司特此澄清與說明如下: 鋰電池為現今市面上應用面最多的儲能設備之一,為目前應用最廣泛且穩定的充電電池,按應用場景分為 「消費性電池」、「動力電池」和「儲能電池」三種。從應用場景來看,「動力電池」主要用於電動汽車、電動自行車以及其它電動工具領域,作為移動電源且採高功率充放電 (1-3C) 供載具車輛使用,對於能量密度則有更高的要求;反觀目前國內外電網級靜置型態儲能系統,絕大多數儲能裝置無需移動屬於慢充慢放 (0.5C-1C) 達到電能轉移之效用,本儲能場依照《經濟部能源署併網型儲能系統設置區域及設置安全規範》、《內政部消防署提升儲能系統消防安全管理指引》,以及《經濟部標檢局戶外併網型鋰電池儲能系統驗證制度》等法規建置,規模跟安全性達到國家最高要求。 本案採用安全性高、全球著名的儲能系統品牌,以整機系統取得國際安全標準UL 9540與IEC 62933-5-2安全證書,並符合UL 9540A燃燒測試之要求與美國消防協會NFPA 855 及國際消防規範IFC的相關規定,無延燒之風險,設備從零組件層級到整機系統層級均符合國際安全認證與台灣在地法規要求。 本案儲能系統採用符合全球最高規格「UL9540A大型防延燒測試」的水冷式電池外,將電池藉由水循環系統來降低溫度;也符合《提升儲能系統消防安全管理指引》明定儲能系統案場之外牆或相當於外牆之設施與鄰近建築物等場所應保持30公尺的安全距離 (所稱「外牆之認定,係以儲能系統燃燒輻射熱或火焰之起點計算,若儲能系統為裝置於貨櫃或箱體內,該貨櫃或箱體得視為相當於外牆之設施,計算與鄰近場所之安全距離),儲能消防規範規定防火牆設置耐燃2小時 (厚度即10公分即可) 本案場施作25公分,高於中央所規範的牆厚2.5倍的鋼筋混凝土防火牆,案場也設置防溢堤、灑水設備、消防蓄水池與鋰電池專用滅火器,皆依照「各類場所消防安全設備設置標準」進行消防設計,使用消防署屬認可安全設備,且設計圖面、計算書應由消防設備師設計及簽證,並提供消防防護計畫、與當地消防單位聯繫提供緊急應變之規劃、每年應定期檢修消防安全裝置。 本起新北市火災事件依目前調查進度顯示之資料為「消費性電池」而非「儲能電池」,而民眾所疑慮斗六儲能案場的部分,所設置的專用滅火器是專為鋰電池火災設計的新型滅火藥劑專用規格,如遇電池過熱情況,依循消防署火災撲滅流程及方式SOP進行操作,更好的滅火方式是不斷噴灑大量的水,以達散熱與降溫,減低和阻斷電池芯產生的熱失控,經消防技師計算,建置80噸消防水池及消防泵浦供消防灑水使用,24小時/365天電池溫度監控,具備故障自動連鎖解聯、多方監控機制、定期巡檢,對於設備的安全性無需顧慮。 盛齊綠能呼籲各界,避免引用容易誤導民眾、或引起不必要恐慌、且與本案場無關之言論,傷害再生能源發展業者之信譽,並能理解與共同支持國家再生能源政策,使人民有更好的用電環境。
