Consultation on removing constrained on payments for generation ramping down
The Authority is proposing to remove constrained on payments for generation that is dispatched down at its maximum ramp rate.
This consultation paper proposes amending the Electricity Industry Participation Code 2010 (Code) by inserting a new clause in Part 13 of the Code to stop constrained on payments to ramp-constrained generators when they are dispatched down at their maximum ramp rate – who would instead be paid the nodal price. In all other respects constrained on payments would not change.
This is a five-week consultation and will close at 5pm on Tuesday, 30 April 2019.
Given the technical nature of the proposal, we would like to hear from interested parties on whether they see value in a workshop or webinar to explain the proposal. Please let us know by emailing the Authority at submissions@ea.govt.nz with “Constrained on payments – Possible workshop” in the subject line. Please let us know by 5pm on Tuesday, 2 April 2019.
Electricity Authority/system operator joint development programme update
The Code requires the Authority and the system operator (Transpower) to agree and publish a joint development programme at least annually. We have recently agreed updates to the programme that reflect progress, changes to priorities, and other project agreements that have occurred since the last publication in August 2018.
The current programme is available on our website. Please email any questions about the programme to info@ea.govt.nz.
Reminder: 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.
Reminder: Registry questionnaire on RESTful web services
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.
The questionnaire closes on Tuesday, 2 April 2019.
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. This project aims to develop a dispatch-based real-time pricing option to deliver more certainty, accuracy and efficiency.
