In Transmission Tomorrow, we predicted that in the future battery technologies will change the operation and role of the National Grid. Learn how we explored the value that batteries can add for New Zealand electricity consumers and the power system, now and in the near term.
Transpower regularly publishes a Transmission Planning Report (TPR) which details the grid asset capability over the next 15 years.
We have evolved our TPR this year to include a Grid Enhancement Approach. These new sections, in each regional chapter, provide more detail on active and potential investment investigations, linking the current investigation status to our planning processes and portfolio funding.
The methodology to allocate the HVDC costs to South Island (SI) generators was changed in 2015. This change involved transitioning from the peak-based metric (HAMI) to an average-based metric (SIMI) from the 2017/18 pricing year (PY). The allocation based on HAMI resulted in a strong incentive for SI generators to maintain generation below established HAMI levels (HAMI limits) thus avoiding increased allocation of HVDC costs. The change to SIMI was intended to reduce this incentive, thus increasing the availability of SI generation capacity.
This publication presents an update to the ten year forecast fault levels report. The Connection Code contained in Schedule 8 to the Benchmark Agreement requires Transpower to publish a ten year forecast of the expected fault levels at each customer point of service annually.
Transpower last published the Ten Year Forecast of Fault Levels in September 2015.
Transpower's report on the availability and reliability of interconnection assets for the year ending 30 June.
Each year Transpower publishes an Annual Planning Report which details the status of all projects that Transpower considers possible over the next 15 years.
A guide to what Demand Response is, why it is important, and how it works.
From April 2008, Transpower is required to use the Electricity Authority's Transmission Pricing Methodology (TPM) to allocate Transpower's revenue requirement via connection, interconnection and HVDC charges for its customers.
This report describes the analysis undertaken by Transpower at the request of the Industry Transmission Pricing Project working group.
