Temporary power plants are necessary energy solutions for power grids or communities that are suffering from downtime. They can be set up to help stabilize towns or industries that are having problems with their local grid and provide much needed back up power until a permanent solution has been reached. You can also look for a power plant test (also known as "elverk test" in the Swedish Language) via various online sources.
When a community or industry's energy demands exceed the capacities of their current plant, a temporary solution is a good way to ensure energy is efficiently provided while a long term strategy is put in place. It's the perfect, non-permanent way to supplement a grid on a large scale and without running up large, unnecessary bills from numerous small solutions trying to do the same thing.
A temporary power plant also offers the ability to implement seasonal peak shaving. This is when a temporary or additional source of power is used during busy or peak seasons to stabilize a supply that might otherwise struggle under demand.
It is often a good and growing solution in countries that experience extreme temperatures or in hydro dependent countries that suffer from a lack of rainfall. It is used to supplement renewable energy sources that are not able to provide the energy needed during times of drought or low wind speeds.
In these tough conditions, a temporary solution can be used to help to prevent outages, and often for only a few hours a day during peak seasons. What's more, because it is only used during peak times, it doesn't accrue costs throughout the year.
Demand is also increasingly on the up due to the number of governments who are attempting to introduce renewable power solutions. These typically dependent on natural resources such as wind or rain and can therefore suffer teething problems best alleviated with some temporary help.
