The first of tens of thousands of felled trees are arriving on Teesside to fuel an environmentally-friendly power station.
The power station requires 30,000 tonnes of timber a year
The Forestry Commission is sending 22,500 tonnes of timber from Cumbria and Northumberland to the £60m Wilton 10 wood-burning power station.
The SembCorp Utilities plant will generate enough green power to heat and light 30,000 homes.
Stockpiles are being stored ready for the plant's switch on next spring.
Timber for the plant is being harvested as part of normal felling operations from Kielder Forest in, Northumberland and Kershope and Spadeadam Forests in Cumbria.
Forestry Commission operations manager Doug Howieson, said: "This is an exciting new market for our timber.
"Using wood produces less emissions than fossil fuels and comes from a renewable source.
"Our forests are managed for people and wildlife, but they could have a crucial role to play in green energy generation."
Kielder Forest District manages 80,000-hectares (200,000-acres) of woodlands in Northern England, all of which have been certified as meeting top environmental standards by the Forest Stewardship Council.
The Wilton 10 boiler will require 300,000 tonnes of chipped wood every year.
About 20% will be supplied by Kielder Forest District and from the Forestry Commission's woods in the North York Moors.
Steve Bishop, biomass manager for SembCorp Utilities UK, said: "The Forestry Commission is one of our key suppliers and it's great to see wood arriving at the site."
