The first intelligent CrossPower energy system by Pfisterer has been up and running at the NATO Energy Security Center of Excellence in Lithuania since the beginning of February. The system was procured as part of NATO’s energy efficiency program “Smart Energy”. The aim of the program is to save fossil fuels. Remote settlements, camps, or off-shore platforms used to have to rely solely on diesel generators for a constant energy supply – fluctuating sources of regenerative energy have always been out of the question for the stable operation of IT systems, operating facilities, or cooling rooms. However, transporting fossil fuels is very expensive and can put lives at risk.
Instead, a system is needed that can supply decentralized, isolated energy networks (known as microgrids) with a stable supply of regenerative energy, no matter what the weather. At the same time, this system needs to be quick and easy to transport so that it is ready to use straight away in the event of critical situations. There is one system that meets all these conditions: the CrossPower energy management system by Pfisterer. Following a successful practical test during a NATO exercise last year, the first system with an output of around 150 kW (up to 2,500 kWh per day) and a storage capacity of 100 kWh is now in use in the Lithuanian town of Marijampolé. All of the system’s components can be transported in 20-feed-ISO containers, thus making sure they can be used as mobile solutions.
“PFISTERER was able to install a highly-complex yet very impressive system within a very short space of time”
says Sigitas Mudris with a smile, commander of the Lithuanian logistics troop.
CrossPower allows diesel generators to be combined with various regenerative energy sources in microgrids. The core of the system is formed by powerful lithium ion batteries and an intelligent control system. This automatically gives preference to solar and wind power whenever they are available. If either sources are limited, the system first falls back on the batteries. The diesel generators are only used to charge the batteries when needed and always operate at optimum conditions. Combining various energy sources saves up to 50% fuel.
