Action from Workshop 3 – SUB010 National Grid NTS to rework the Easington scenario on the assumption that an exchange rate cap of two existed. Results from scenario presented at workshop 3 Revised obligated levels Easington: 139.9 mscmd (previous obligated + 10) Donor ASEPs: Reduced where capacity substituted away Aldbrough 38.8 mscmd (no change) Hornsea 20.6 mscmd (minus 0.9) Hatfield Moor 1.5 mscmd (minus 0.8) Theddlethorpe 7.3 mscmd (minus 49.2) Bacton 123 mscmd (minus 41.7) Teesside 44 mscmd (no change)

Action from Workshop 3 – SUB011 National Grid NTS to calculate SO revenue impacts per 1 mscmd of new ASEP capacity as a consequence of each of the projects outlined by JBa. Assessment undertaken for 10 mscmd.
