15. Quality and security of supply 15 What, if any, changes to the gas DPP quality standards (or information disclosure requirements) could be made to provide the ‘right’ incentives in respect of the security of supply? What changes to the gas DPP quality standards could be developed to encourage the ‘right’ investments more generally? High-impact, low-probability events?

16. Major projects 16 What kind of scrutiny should be placed on investments key to security of gas supply under either a DPP or CPP, and what is the appropriate regulatory mechanism for dealing with projects where there is a single project makes up a very high proportion of total capex (eg, DPP re- openers for specific projects, single issue CPPs / ‘mini’ CPPs) etc?
