Consultation on remaining elements of real-time pricing
We are consulting on three remaining elements of the design for spot market settlement on real-time pricing (RTP). This project aims to develop a dispatch-based real-time pricing option to deliver more certainty, accuracy, and efficiency.
The three remaining elements of the design presented in this second consultation paper are:
full details of our proposal for ‘dispatch-lite’ (a form of dispatchable demand for smaller purchasers), now expanded to include distributed generation
the pricing that should apply during shortfalls in instantaneous reserve cover
a process for reviewing the dollar amounts assigned to the default scarcity pricing values.
The consultation paper also provides the final draft of the proposed amendments to the Electricity Industry Participation Code 2010.
Public briefing for remaining elements of real-time pricing – 29 March
The Authority, with the assistance of the system operator, is holding a public briefing for the real-time pricing project. This project aims to develop a dispatch-based real-time pricing option to deliver more certainty, accuracy, and efficiency. We have been considering three real-time pricing design elements and have now published a consultation paper. At the briefing you will hear about what we are proposing and have the opportunity to ask questions.
The public briefing will be held on Friday, 29 March 2019 between 9.00am and 2.00pm at Transpower in Wellington.
Post-implementation review of the wholesale settlement and prudential security arrangements
The Authority has completed a post-implementation review of the wholesale settlement and prudential security arrangements introduced in March 2015. Our analysis shows the initiative has been successful, delivering benefits far in excess of the implementation costs.
We would like to know if participants would use RESTful web services in the registry. Currently, the registry has a SOAP based web service, which functions reliably but is not used by all participants. Participants need to employ specialists to develop SOAP connectors between the registry and their back-office systems, which increases the cost due to custom development and maintenance requirements.
Most modern tools such as Customer Relationship Management (CRM) and workflow/work tracking systems base a lot of their operation around REST. A number of these tools have out-of-the-box functionality that reduces the need for participants to employ specialists.
As registry users, we would like your feedback as to how a RESTful web services interface would be used and any specific requirements that would benefit you.
