The Energy Heritage Collection specialises in the national energy sector, namely the electric sector, and has a collection that dates back to the 19th century.
It is made up of approximately 3500 pieces inventoried into thematic units, such as measuring devices and meters, household appliances, illumination and lab equipment, among others.
Building the collection, which inherited all of the original machinery and equipment from the Tejo Power Station, began in 1998 by gathering and cataloguing pieces and equipment that were spread across several EDP facilities, in order preserve, conserve and divulge a historic legacy inherited from the numerous companies that produced, transported and distributed electric energy in the country. This collection also includes other pieces that were gifts from private and institutional entities.
The Power Station Circuit allows visitors to discover an important part of this collection.
