More about the ESS

An ESC is a tradeable certificate. ACPs create ESCs from eligible activities. Scheme participants surrender ESCs. 

ESS activities and equipment must meet eligibility requirements. 

These are specific activities that are excluded from the scheme. They cannot be used to create ESCs.
