台電文創攜手物外YSTUDIO，結合台電的永續循環精神與物外對精品文具的專注，以創意與精良技術將退役封水銅條轉化為生活中的文創用品。製作過程中保留銅條原始紋理，CNC切削後回收金屬碎屑再熔煉，實現零廢棄循環工法，讓這些曾肩負水力發電任務的銅條，持續承載著歷史的記憶，也成為書寫生活的一部分。

TPCreative collaborates with YSTUDIO, blending Taipower’s commitment to sustainability through circular economy with YSTUDIO’s dedication to crafting premium stationery. Through creativity and craftsmanship, they transform decommissioned brass sealing strips into lifestyle products. The process preserves the original texture of the brass, while CNC cutting recycles metal shavings for re-melting, achieving a zero-waste closed-loop production. These brass strips, once part of hydropower generation, now carry the legacy of energy history into everyday writing experiences.

要了解封水銅條的故事，就得從日月潭的水力發電說起

1919年，台灣總督府成立台灣電力株式會社，並開啟日月潭水力發電工程，以水位高低落差轉換的能量來推動發電機。
1950年，水力發電曾經肩負全台灣過半的發電總量，當時的生產製造、家電運作、電影播放都有賴台電與日月潭的辛勤作業，照亮了整個時代。
2024年，日月潭依然是全台灣最複雜的水力發電系統，不僅能像常規水力發電廠一樣利用水位落差進行發電，更能善用上下池抽水蓄能，成為全台最大的儲能電池。

The story of the Brass Sealing Strip starts with the hydropower of Sun Moon Lake.

In 1919, Government-General of Taiwan founded the Taiwan Electric Power Co. Ltd. and implemented the Sun Moon Lake hydropower project, in which water level difference was adopted to convert energy for driving generators.

In 1950s, hydropower once was responsible for more than half of total electricity generation in Taiwan. The manufacturing, household appliances, and film screenings all depended on Taipower and the diligent operation at Sun Moon Lake power plants. It could be said that hydropower plants illuminated the entire era.

To date, Sun Moon Lake remains one of the most complex hydropower systems in Taiwan. It not only generates electricity using water level differences like conventional hydropower plants, but also effectively utilizes pumped storage in upper and lower pools. This has led Sun Moon Lake becoming the largest energy storage battery in Taiwan.

We’ve thoughtfully integrated elements of the Sun Moon Lake hydropower system and power plant into the design. The outer packaging features a laser-etched circuit diagram that gleams with electric flow under refracted light, while the inner box is laser-etched with contour lines of the Sun Moon Lake area, creating shimmering ripples of light that evoke the beauty of the lake’s surface.

封水銅條－抽蓄電廠變身的關鍵

封水銅條是抽蓄發電機組中不可或缺的零件，負責密封導翼間隙，確保機組在發電與抽水模式間切換順利。它由鋁青銅與砲金合金製成，具備優異的強度與耐用性，廣泛應用於船用螺旋槳與軸承等設備。這些退役的銅條來自日月潭旁的大觀與明潭發電廠，因每部機組僅十年一次大修且非每次都汰換，四年內僅收集到180條，極為珍稀。再製過程中保留原始紋理，表面自然生成的氣孔，是歲月與工藝交織的獨特印記，如今化身為承載水力記憶的書寫工具。

Brass Sealing Strip

The Brass Sealing Strip is an essential component in pumped-storage hydropower generators, sealing the gaps between guide vanes to ensure smooth switching between generation and pumping modes. Made from aluminum bronze and gunmetal alloys, it offers excellent strength and durability, commonly used in marine propellers and bearings. These retired strips come from Taiwan’s Daguan and Mingtan power plants near Sun Moon Lake. Since each generator undergoes major overhaul only once every ten years, and replacement is not always needed, it took four years to gather just 180 strips, making them truly rare. During the remelting process, the original texture and natural pores are preserved—each pen becoming a unique fusion of craftsmanship, history, and the enduring memory of hydropower.

因為珍貴，所以更加珍惜。
每一根封水銅條都經過十年以上的水流沖刷，歷經四年蒐集而來—每一件，都是時間淬鍊的禮物。

Because it’s rare, we treasure it even more.

從供電到書寫的永續旅程

日月潭水力書寫計畫以180支、約390公斤的退役封水銅條展開循環再造，透過CNC切削、熔煉翻砂、切銷等工法，讓退役材料在製程中被完整運用，實現零廢棄目標。水力筆的循環材料使用率達70%，筆座更達到100%無添加新料。這些再生的筆與筆座，延續了封水銅條的使命，從供電轉化為書寫，承載著日月潭水力電氣工程的歷史與文化價值。電力點亮了城市與工廠，也推動台灣邁向現代文明；如今，我們以筆作為載體，將電力的精神透過書寫，傳遞至日常生活的每一刻。

A Sustainable Journey from Power to Pen

The Sun Moon Lake Hydropower Writing Project repurposes 180 retired Brass Sealing Strips—totaling about 390 kilograms—through circular production. Using CNC cutting, remelting, sand casting, and machining, the materials are fully utilized, achieving zero waste. The Hydropower Ballpoint Pen uses 70% recycled material, while the pen stand achieves 100% recycled content with no added materials. These regenerated pens and stands extend the mission of the Brass Sealing Strip, transforming its role from generating power to inspiring writing, carrying the historical and cultural legacy of Sun Moon Lake’s hydropower engineering. Electricity once lit up cities and factories, driving Taiwan’s path to modernity; now, through each stroke of the pen, we carry that spirit of energy into daily life.
