1. Market-wide Half-Hourly Settlement
  2. Migration - accreditation, planning and terminology

Could you please confirm that you’re planning to qualify as an agent in MHHS and will be capable of operating in legacy and MHH over the migration period with no impact to operations?

We are preparing to qualify in the Advanced Data and Metering Services roles and our systems will be able to operate before and after the MHHS programme is complete. 

We are also seeking an update on your qualification status. If you have a specific MHHS mailbox for us to contact please send it over. 

We will make sure you are kept as up to date as possible and if you do have any questions about MHHS, you can ask them by clicking on the button at the bottom of this email.

Also, will new MHHS references will be communicated to us once confirmed? i.e. Contract/Service/Service Level references. 

We will make sure you are kept as up to date as possible and will be adding information and FAQs to our MHHS hub.
