Security of electricity supply is important and for this reason a back-up fuel to LPG is often a requirement. This is especially critical in smaller isolated power systems with a limited number of plants and units in the system.
Wärtsilä offers two different multi-fuel solutions that use LPG as fuel. One solution can, during operation, be switched to run on diesel as a back-up fuel. This is valuable not only in the case of a disruption in the LPG supply for any reason, but also in case of e.g. a seasonal LPG price hike. The other solution burns either LPG or natural gas, and is ideal for plants where natural gas is expected to be available in the future. Also, in small and medium-sized power systems with varying system demand, large single-unit power plants can be problematic. Here flexible baseload, multi-unit power plant solutions as provided by Wärtsilä are ideal. The plants give both the highest possible availability at system and plant level, as well as the highest possible overall efficiency for the power system.
