Aiviekste Hydroelectric Power Station
Aiviekste hydroelectric power station is the first hydroelectric power station constructed in Latvia. It is located on the Aiviekste River. The power station was commissioned in 1925 and until 1938 it was the largest in Latvia. The power station was decommissioned in 1969; however, in 1988 it was decided to restore it. In 1993, the power station restarted power generation. The power station has total capacity of 0.8 MW. In 2007, it generated 3GWh of electricity. The power station is operated by Latvenergo Latvenergo is a state-owned electric utility company in Latvia. Latvenergo Group provides energy supply services in the Baltics. The Group comprises the parent company Latvenergo AS, with decisive influence, and five subsidiaries. Latvenergo ....

Watt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : ...

Aiviekste River
Aiviekste is a river in Latvia.Latvian Soviet Encyclopedia, p. 1-99. It begins at Lake Lubāns (the largest lake in Latvia) and drains into the Daugava (the largest river in Latvia). Aiviekste is the largest tributary of Daugava in Latvia. Aiviekste, along with the Pededze, forms the unofficial border between two historical Latvian regions Vidzeme and Latgale, although the administrative border was slightly different. The river is 114 kilometers long, with annual drainage 1.81 km³. Aiviekste is about 10-12 thousand years old, formed at the end of the last ice age and nearly after the ice age. Nearly a quarter of the river's flow is unregulated, but most of the river has been excavated, including with explosions. Aiviekste flows from the northern end of Lake Lubāns, where it does a wide semicircle and then turns southwest. At this stage is the smallest drop, in addition, here Aiviekste receives the largest tributaries Pededze, Bolupe and Iča. Furthermore, it was straighte ...
