Svartsengi is a major high-temperature geothermal field north of Grindavík. It is also the location of Iceland's first combined geothermal power plant, which produces both hot water and electricity.

How is Svartsengi connected to the Blue Lagoon?

Mineral-rich separated geothermal brine from the Svartsengi operation collected in a lava-field discharge pond. That pond became the foundation of the Blue Lagoon.

Can visitors enter the Svartsengi Power Plant?

Do not treat the operational power-plant complex as a public sightseeing site. Remain on legal public roads and viewpoints and respect all fences, barriers and closures.

Is geothermal water from Svartsengi pumped directly into homes?

No. The geothermal fluid is hot and saline. Its heat is transferred to clean freshwater through heat exchangers, and that heated freshwater is then distributed to consumers across Reykjanes.

Is Svartsengi in an active volcanic area?

Yes. Since late 2023, ground uplift and magma accumulation beneath Svartsengi have been closely monitored in connection with activity on the Sundhnúkur crater row. Conditions can change quickly, so always check current official hazard information before visiting the area.

At a Glance

Visit time

Allow about 20–40 minutes as part of a wider Reykjanes route; Svartsengi itself is primarily an interpretive landscape rather than a conventional walk-in attraction.

Best season

The landscape can be seen year-round when roads and official safety guidance allow access. Clear daylight is best for understanding the lava-field and power-plant setting.

Access

The geothermal field lies north of Grindavík beside the Blue Lagoon and Svartsengi Power Plant area. The power plant is operational infrastructure; stay on public roads and outside fenced or restricted areas.

About 斯瓦茨恩吉

斯瓦茨恩吉是雷克雅内斯半岛五大高温地热区之一，位于格林达维克以北。这里自1976年开始利用地热为区域供暖，自1978年开始发电。地热系统为雷克雅内斯地区的社区提供热水，而发电过程中排出的富含矿物质的地热卤水形成了排放池，后来成为蓝湖的起源。斯瓦茨恩吉把冰岛的自然史与人类利用地热的历史结合在一起。这个名字源自过去骑马旅人使用的一处休息地；如今，这里则是冰岛地热工程与资源循环利用的重要代表。自2023年底以来，斯瓦茨恩吉还因地面隆起和地下岩浆积聚而成为火山监测的重要区域。

History & Background

斯瓦茨恩吉的现代能源开发始于1969年的地热调查。1971至1972年的钻井确认了高温地热系统，但盐度问题促使工程师采用热交换方式加热淡水。1976年开始区域供暖，1978年开始发电，斯瓦茨恩吉由此成为冰岛第一座综合地热电站。地热生产排出的矿物质卤水形成了后来蓝湖的基础。

斯瓦茨恩吉是雷克雅内斯半岛五大高温地热区之一，也是冰岛地热能源发展史上的重要地点。1969年，格林达维克开始研究利用这里的地热为住宅供暖。1971至1972年的钻井发现地下温度超过200°C，但地热流体盐度很高，无法直接输送到住宅，因此工程师开发了热交换系统，用地热蒸汽和卤水加热清洁淡水。地热利用于1976年开始，1978年开始发电，使斯瓦茨恩吉成为冰岛第一座同时生产热水和电力的综合地热电站。经过七个发展阶段，目前许可的发电能力最高为85 MW，热能生产能力约为200 MW。生产过程中分离出的富矿物质卤水在电站旁的熔岩中积聚，形成排放池，后来发展成著名的蓝湖。斯瓦茨恩吉这个名字则更古老，源于过去骑马旅人的休息地。自2023年底以来，这里还因地面隆起和地下岩浆积聚而受到持续监测。前往附近时应遵守所有限制，并查看最新官方火山风险信息。

Folklore

Story & Folklore

过去，斯瓦茨恩吉只是雷克雅内斯半岛上骑马旅人的一个休息地。到了20世纪，这片土地成为改变当地能源体系的重要实验场。钻井发现的地热流体非常热，却因盐度过高不能直接进入住宅。工程师因此利用热交换器把能量传递给清洁淡水。1976年，热水首次输送到格林达维克；1978年开始发电。剩余的富矿物质卤水在黑色熔岩中聚集，形成乳蓝色水池，最终发展成蓝湖。如今，随着2023年底以来的地面隆起和岩浆积聚，斯瓦茨恩吉又成为冰岛最受关注的火山监测地区之一。

💡 Did You Know?

Svartsengi's name comes from an old stopping place used by horsemen, while the modern power plant stands on Illahraun — lava that flowed in 1226.
