本文提出 Enerfree Tech 的商業計畫。Enerfree Tech 是一家位於台灣的能源服務公司，專注於工業用電池儲能系統。透過能源即服務（Energy-as-a-Service, EaaS）模式，公司協助工業客戶導入電池系統，使其不需要支付前期設備成本，也不必自行面對技術上的複雜性。這與台灣較常見的做法不同，因為多數工業用戶通常是自行購買儲能設備，或購買再生能源憑證以符合政策要求。相較之下，Enerfree Tech 扮演第三方營運商的角色，為客戶提供 BESS 設備的融資、安裝與管理服務。

公司的收入主要來自電價套利與經常性的資產管理費。本商業計畫中的財務預測，是根據實際設備效能資料與目前台電電價表所建立，而不是單純依賴理論假設。公司也與一家國內 BESS 供應商合作，其系統已被應用於半導體等級的工業環境中，這進一步強化了本模式的技術可信度。在五年的預測期間內，本計畫以三種安裝情境進行測試。Enerfree Tech 在三種情境下皆於第二年開始獲利，第五年的淨利率則從最差情境的約 22% 到樂觀情境的超過 30% 不等。依據客戶採用速度的不同，公司累計安裝量介於 460 至 1,350 台之間，並需要分階段投入新台幣 1.2 億至 2.7 億元的股權資金。其中，累計安裝 1,050 台的基本情境被視為最符合現實的規劃假設。

This paper presents a business plan for Enerfree Tech, a Taiwan-based energy service company focusing on industrial battery energy storage. Using an Energy-as-a-Service (EaaS) model, the company helps industrial customers adopt battery systems without paying upfront costs or facing the technical complexity themselves. This is different from the more common approach in Taiwan, where most industrial users either buy storage equipment themselves or purchase renewable energy certificates to meet policy requirements. Instead, Enerfree Tech acts as a third-party operator that finances, installs, and manages BESS units for its clients.

The company earns revenue from energy arbitrage and recurring asset management fees. The financial projections in this business plan are based on actual equipment performance data and current Taipower tariff schedules, rather than purely theoretical assumptions. The company also works with a domestic BESS supplier whose systems are already used in semiconductor-grade industrial environments, which strengthens the technical credibility of the model. Over the five-year projection period, the plan is tested under three installation scenarios. Enerfree Tech becomes profitable in Year 2 in all three cases, with a Year 5 net margin ranging from about 22 percent in the worst case to more than 30 percent in the optimistic case. Depending on the pace of customer adoption, the company installs between 460 and 1,350 units cumulatively and requires between NT$120 million and NT$270 million in staged equity funding. The base case, with 1,050 cumulative units, is treated as the realistic planning assumption.
