Through a standardised and accurate IT system, Eress ensures:

Lower energy costs
The benefits with Erex are not only environmental, but also financial. Up to 30 per cent reduced energy consumption means considerable lowered costs for the whole railway sector. With rising energy prices, the savings will be even bigger in the future.

Lower environmental impact
On measured journeys Erex has led to decreased energy consumption with up to 30 per cent. Thus lessening the environmental impact. With more and more countries using Erex, the total eco-effect is considerable.

Increased competitiveness
Erex increases the competitiveness of the railway. It is the only system that works truly cross-border, independently from the countries or train operators involved. Erex is also open-source and easily adapted to any existing system. This makes it a crucial cornerstone in building a single European railway area.

Eress organisation and its Erex system give obvious advantages for railway business:

A single European railway area
Erex is the only system that works truly cross-border, independently from the countries or train operators involved. Erex is also open-source and easily adapted to any existing systems. This makes it a crucial cornerstone in building a single European railway area.

Traffic moved from road to railway
Erex system makes the railway a more attractive choice. Through making the railway more efficient and reducing its energy consumption and costs, Erex increases the competitiveness of the railway against all other transportation modes. It helps moving traffic from road to railway.

Increased interoperability
With a more attractive railway, there will be stronger forces for transporting goods by rail. Directly or indirectly, this is likely to increase the efforts for enlarged interoperability between different transportation modes.

"Energy settlement systems facilitate energy supply from a competitive energy market"

Increased cross-border rail operations requires the use of different energy suppliers. Energy settlement systems helps Rail Undertakings and Infrastructure Managers monitoring their energy consumption and related costs. This, of course, encourages competition; the systems facilitates for energy supply from a competitive energy market. Concepts such as Third Party Access encourages operators to buy electricity at an open and non-discriminatory way.
