Notes: |
| 1. RO period is the 12 months from 1 April to 31 March |
| 2. Capacity is the total installed generating capacity in kW |
| 3. Load Factor is calcuated for the 12 months of the RO period. |
| 4. An asterisk (*) denotes fewer than 12 months of data is available in a given period; the actual number of months of data is in brackets in the first column. |
| 5. The number of ROCs per MWh depends on whether the generator is subsidised under the RO and, from April 2009, the band into which the generator and technology falls. |
