Longitude: approximately 3°50′ E
Latitude: 44°07′ N
GHI: 1914 kWh/m2@35º
Space opportunities: the site has availability of a confers ground plane.
Description of the energy scenario
There are two main generation equipment: On site there are also 3 hot water boilers “Lacaze Hydrogaz” with incorporated water storage tank: one is intended to produce hot water for tank cooking (bain marie at 80°C) and two are intended to maintain rooms at the desired temperature (60°C) via heat exchangers and fans.

Description of the industrial process and current control
The ABC Industries demo site specializes in the manufacture and distribution of high-quality fresh meat products for professionals in the food industry. Since 1866, when it was founded, the company has been able to retain the fundamental values of its founders, butchers and craftsmen. ABC produces cooked ham and dry sausage through the processes shown in the Block Flow Diagram presented in Figure 5-2.
Currently, a 3.8 t/h boiler produces steam at 9 bar (about 175°C); this boiler runs on natural gas and consumes approximately 85% of the total consumption of gas of the site. The thermal energy demand of the processes is distributed at monthly level as shown in Figure 5-3 whereas the daily distribution of demand is presented in Figure 5-4.
The steam is then used mainly for:
Cooking ham in an oven at about 70°C (this steam is lost – without condensate return)
Pasteurisation at about 96°C via a tubular exchanger (this steam comes back, after use, in form of condensates and is stored in the boiler feed tank)
Heating of domestic hot water for process use but mainly for the cleaning of rooms and production equipment (at about 55°C for an amount of 250 m3/day – consumption of this water occurs between 4 PM and 11 PM)
Water heating for washing system (churns / ham molds) during production process
