Maagaasivõrk

Maagaasivõrk, or natural gas network, is the system of pipelines, compressor and regulating stations, meters, and related equipment that transports natural gas from producers to end users. It includes high‑pressure transmission pipelines that move gas between regions and import points, lower‑pressure distribution networks that bring gas into cities, and service lines that connect to individual buildings. The network also comprises odorization facilities to give gas its distinctive smell, pressure-control stations, and metering and reconciliation infrastructure for measurement and billing. The system is designed to maintain safe, reliable, and economically viable gas supply while balancing supply and demand.

Operational responsibility is typically divided between a transmission system operator and several distribution system operators. Regulators supervise safety, market access, and price oversight, and ensure third‑party access to the network. The maagaasivõrk is built and maintained to national and European standards, and is subject to routine inspections and integrity management programs to prevent leaks and ruptures.

Safety and reliability rely on continuous monitoring, leak detection, corrosion protection, and automated control systems. Gas is odorized to aid leak detection, and emergency procedures are in place for suspected leaks, fires, or network outages. Regular maintenance, pressure management, and metering accuracy are essential for customer protection and system efficiency.

Historically, gas networks evolved from manufactured town gas to natural gas as supplies diversified. In many countries, the maagaasivõrk forms a critical part of energy infrastructure, with ongoing modernization to improve efficiency, integrate renewable and low‑carbon gases, and prepare for potential hydrogen blending.
