põhivõrgu

Põhivõrgu is an Estonian term that translates to "main grid" or "primary network". It most commonly refers to the electricity transmission network in Estonia. This high-voltage network is responsible for transporting electricity from power generation plants to regional distribution networks and major industrial consumers across the country.

The Estonian main grid is operated by Elering AS, a state-owned company. Elering's responsibilities include maintaining and developing the infrastructure, ensuring the reliable supply of electricity, and managing the flow of power across the network. The main grid plays a crucial role in the stability and security of Estonia's energy supply, connecting the country to neighboring networks in Latvia and Finland, which allows for electricity trade and enhances overall system resilience.

The infrastructure of the põhivõrgu consists of high-voltage power lines, substations, and control systems. Investments are continually made to upgrade and modernize these components to meet growing demand, integrate renewable energy sources, and comply with European Union standards for energy market integration and grid security. The safe and efficient operation of the põhivõrgu is paramount for the functioning of the Estonian economy and the daily lives of its citizens.
