Augstsprieguma tīkls
Latvian electricity transmission system operator
Augstsprieguma Tīkls AS (AST) is an independent electricity transmission state system operator in Latvia. It operates power systems with voltages of 110 kV and above, which is leased from Latvenergo. It is also the main shareholder of Conexus Baltic Grid, a unified natural gas transmission and storage operator in Latvia.
History
On 15 October 1939 the Ķegums power plant and the first substation in Riga start operation. This day is considered as the beginning of AST.
AST was a part of Latvenergo. On 2 January 2012, it was unbundled from Latvenergo and the Ministry of Finance of Latvia became the sole shareholder of AST.
In December 2017, AST bought from Uniper Ruhrgas International and Itera Latvija 18.31% and 16.05% stakes in Conexus Baltic Grid, a natural gas transmission system operator in Latvia, for €57.394 million.
Operations
AST operates Latvian power systems with voltages of 110 kV and above, which is leased from Latvenergo. Its overall strategic goal is to ensure the security of electricity supply of Latvia, to provide a continuous electricity transmission service.
Latvia and the Baltic states have historically operated in the IPS/UPS grid, controlled by Russia. The origins of the idea to synchronize with the European grid go back as far as 2007, when the prime ministers of the Baltic states proposed the idea of investigating this possibility.
Begin with the source’s own compact description: “Augstsprieguma tīkls” is latvian electricity transmission system operator. The dossier treats that line as a proposition to test through Augstsprieguma, tīkls and Latvian, not as a finished interpretation.
Why this record matters
The phrase “latvian electricity transmission system operator” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 14, 2026. The linked authority identifier is Q16822050. VIAF identifies the subject as 120145424171386790432. Authority coordinates are 56.933, 24.181. None of the 4 selected statements returned an explicit reference. The first chronological checks are 1939, 2012, 2017 and 2007.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
