摘要
地熱發電是我國重要的再生能源之一,國內之地熱潛能區計27處,初估發電潛能約1,000 MW。政府訂定2025年地熱發電之目標為200 MW,目前已有廠商投入地熱發電開發的行列。由於 我國地熱潛能區多數分布在地質災害敏感區,如何確保開發後電廠的安全是重要的課題。本研究提 出2個地熱電廠開發的重要議題,(1)背景條件:透過地熱區之地理與地形等基本人為與自然特性, 篩選出基本條件較好的潛在場址,作為場址開發的優先條件;(2)限制條件:透過潛在場址的環境敏 感區圖資整合分析,事先了解環境敏感區之限制與影響,提供未來電廠設置規劃參考。本研究以宜 蘭縣清水與土場-仁澤等兩處開發中地熱潛能區為例,進行背景條件比較及廠址環境敏感度分析。 以背景條件而言,清水地熱區優於土場地熱區;在限制條件部分,清水地熱區重要設施應注意避開 土石流,土場-仁澤地熱區應注意避開山崩與地滑潛勢區。

Geothermal power is one of the important renewable energy resources in Taiwan, there are 26 geothermal potential areas with about total 1,000 MW power generation potential that estimated in early. Based on the potential mentioned earlier, the government has set a target of 200 MW for geothermal power generation in 2025. So far, manufacturers have launched to construct geothermal power plants. Since most of the geothermal potential areas in Taiwan are distributed in sensitive areas of geological disasters, how to ensure the safety of power plants after development is an important issue. This study proposes two important topics for the development of geothermal power plants. (1) Background conditions: Through the basic anthropogenic and natural characteristics such as geography and topography of the geothermal area, screening potential sites with better basic conditions as the priority conditions for site development (2) Restrictive conditions: Through the integration analysis of environmental sensitive areas of potential sites, prior knowledge of the restrictions and impacts of environmentally sensitive areas, and provide recommendations for future power plant setting planning. In this study, the development of the geothermal potential area in the Qingshui and the Tuchang-Renze geothermal areas in Yilan County were taken as an example to compare the background conditions and the environmental sensitivity of the site. In terms of background conditions, the Qingshui geothermal area is superior to the Tuchang-Renze geothermal area; in the restricted condition, important facilities in the Qingshui geothermal area should pay attention to prevent the problems of earth and rock flow, and the Tuchang-Renze geothermal area should avoid developing in the landslide potential area.
