The following Energy System template describes the basic concept for an installation of a Kirell Power Micro-grid system and of its features providing for the surety of power from conventional and renewable energy.
‍
The “Client Energy Model” presented for generation systems represented in this discussion, is for a large Food Processing plant. The two plants require the generation of power for operations on a 24/7 basis, including the production of steam used in the food product processing facility. Again, due to Co-Gen nature for steam production required for the facility, operating natural gas generation equipment is the most capable for providing the energy needed for the facility.The core generation equipment used in the Micro-Grid system is;
• Natural Gas Engines or Turbines, 12MW capacity base load. 12MW of additional capacity with Engines for load following capacity and/or redundancy,
• Storage (Lithium Ion or Lithium Iron Phosphate Batteries) 10MW capacity 4.5MWh x 2 hrs.
• Solar, 7MW capacity
• Control system with Algorithms balancing generation systems
• New sub-station installation with a ring buss configuration (estimated at 34/36 MVa)

Using base load power generation from Natural Gas units (engines or turbines), provides the Co-Gen requirement for food processing facility. Due to the nature of the facilities operations, it is most efficient to provide heat from co-generation using duct fired boiler directly from the Natural Gas turbines rather than using boilers directly for the steam production required. There is an estimated 18% efficiency gain on duct fired boilers compared to conventional boilers at about 80% currently.

The facility retains its grid interconnection and is used to facilitate potential off-take agreements for the excess on site capacity, not primarily as backup power to the facility, unless called on due to an emergency situation.

The primary objective for this particular Co-Gen system is the absolute 100% surety that there is no power interruption in the plants during the facilities operating season. The facility processes 400 tons a day of tomato paste or diced tomato product (16,000 tons of tomato’s daily) for approximately 100 days a year.
