Project details

Carie is a ‘run-of-river’ hydropower design. Water is abstracted from the river and diverted through the penstock (pipe) to the powerhouse where the power is generated via the turbine. The water is then discharged through the tailrace back into the river.
No water storage is required and notches in the intake weirs ensure that a level of water continues to flow down the section of river between the intake and the tailrace. When water flows are low, all the water stays in the river and in times of spate, most of the water also carries on down the river.

GreenPower owns and operates the project.

One of the main challenges during construction was the possibility of finding unexploded ordnance (UXO) on site. Anecdotal evidence of UXO from WWII in the area had been received.

One live mortar was discovered which was blown up in situ by the Ministry of Defence. Several other redundant mortars were also discovered which were disposed of. The presence of UXO did cause delay to the project programme, however, through collaboration with the on-site team to work on other parts of the site the schedule of works was maintained and most importantly the safety of all workers on site was ensured at all times.
