A new survey has found British businesses are seriously concerned about rising gas and electricity prices.
Only 66% of businesses interviewed said they had drawn up a strategy to manage energy bills.
Business gas and electricity use is unlikely to dwindle as the year progresses, even with double-digit price rises.
RWE npower found many companies had now prioritised generation of their own energy, with many major companies already pressing ahead with biomass, wind turbines and combined heat and power plants.
David Cockshot, from npower, said: "As demand on the grid starts to become a major issue, large energy users in particular will need to look at new ways to manage their energy more intelligently; whether through self generation or through demand management tools such as load management."
