The NEPTUN system protects water engineering facilities against fish entering their area of operation. The efficiency of this technology is confirmed by inspections and tests carried out by independent entities throughout the world.
The Neptun technology is based on an animal-friendly method of generating an increasing non-linear electric field in the aquatic environment.
3600 MWh more energy can be generated by the power plant on the Madeira River in Brazil due to the implementation of the NEPTUN system (by eliminating two downtime days of the 75 MW turbine) – MORE – IMPLEMENTATIONS

In addition to the NEPTUN electric barrier system, PROCOM SYSTEM offers complementary behavioral fish deterrent technologies designed to meet site-specific hydraulic, environmental and regulatory requirements. Depending on biological conditions, migration patterns and project constraints, alternative or hybrid configurations may be considered.
Other available technologies include:
Technologies based on acoustic deterrence, bubble curtain systems, or light stimulation may operate as standalone solutions or in combination with NEPTUN as part of an integrated fish protection strategy.
Between September 28 and 30, 2025, we took part in a technical visit organized for representatives of Swedish companies, including AFRY, Statkraft, Uniper, Fortum Sverige, Vattenfall, Tekniska Verken, and Skellefteå Kraft AB. During the event, we had the pleasure of presenting the NEPTUN electric barrier systems installed on the Meuse River in Grande Malades and… Read more
On September 2–5, we had the pleasure of participating in the international SUSHP 2025 – Sustainable Hydropower conference in Austria, where we presented our NEPTUN solution. 💧 The NEPTUN system is a durable and effective fish protection technology that supports the balance between renewable energy production and the preservation of aquatic biodiversity. We would like… Read more
