DEPARTMENTS ACROSS ESTONIA

We keep Estonia’s power grid running in every situation

We maintain more than half of Estonia’s high-voltage substations and build electrical installations across the country, from Jõhvi to Valga. Our 4 departments and 35 employees keep our national grid running every day — for almost 20 years now.

High-Voltage Substation Maintenance

330 kV110 kV

We maintain 8 of Estonia’s 330 kV substations and numerous 110 kV substations across the country — periodic servicing, repair, and fault clearance for primary and secondary substation equipment. We have the technology and training to service fluorinated-gas-filled electrical equipment, as well as oil-filled equipment.

SF6 Gas Handling

High-voltage equipment can contain tens to hundreds of kilograms of SF6. One kilogram of this gas is equivalent to 23.5 tonnes of CO2 — roughly the same as driving nearly 157,000 km in a petrol car, or almost four times around the globe. Filling and emptying the equipment requires specialized equipment and training.

Newin’s Role
1
Phase 1: We built the grid-connection substation with a bidirectional 110 kV grid link — the foundation supporting all of the plant’s generation and energy storage, connecting the solar plant directly to the transmission grid.
2
Phase 2: As part of the park’s expansion, we installed additional energy storage capacity, bringing the plant’s total capacity to 25 MW.

ENVIRONMENT

We Protect the Environment

Every project starts with the question of what mark it leaves behind. We avoid pollution and handle hazardous waste responsibly.

QUALITY

We Uphold Standards

Quality isn’t an endpoint for us, but an ongoing process — every material and every job undergoes strict inspection.

SAFETY

We Look After Our People

High voltage doesn’t give a second chance. Proper protective equipment and continuous training are part of every workday.
