The differentiation is carried out by the neural network, which functions as the basis of the forecast calculation in each zone. The neural network is well proven, stable and very fast. • Delay intervals of heat consumption in accordance with source.

Mentor Planner Version 8 is an automated tool for planning and reporting in the production of heat and power plants. This way Silkeborg combined heat and power plant can target the best possible production schedule while simultaneously freeing resources. • “Instead of spending three hours a day on planning the production of the plant, we can spend three quarters of an hour on that task. That way Mentor Planner helps us to not only to produce according to the highest possible profit but also to free resources for other tasks,” says Lars Mikkelsen. • First class service • • At Silkeborg combined heat and power plant they used an earlier version of Mentor Planner before deciding to upgrade to the new Version 8. “Not many days went by from deciding to upgrade our existing Mentor Planner until everything was running smoothly with Version 8. • In a normal running-in period problems often occur, but in this case it was completely problem-free. We must say that OE3i have delivered an above average job and that the service has been first class,” says Lars Mikkelsen. • • • Lars Mikkelsen and his colleagues at Silkeborg combined heat and power plant attach great importance to the way Mentor Planner presents data, takes weather into calculation and plans the schedule of the plant in accordance with the greatest possible profit. “By using Mentor Planner we are able to simply plan a better production schedule than if we had to use hours and hours on doing the same job in a spreadsheet layout. Mentor Planner does the same – only easier, more effective and without errors,” says Lars Mikkelsen. OE3i ApS Hunderupvej 48 5000 Odense C Email: [email protected] Telefon: 21 20 72 20 10
