TRANSGRID, the owner, operator and manager of the high voltage electricity transmission system in NSW, has responded to the Manning Alliance’s criticisms of its planned Stroud to Gloucester power line upgrade, as reported in last week’s Courier.
It says “the conclusions being drawn by the Manning Alliance in this instance are generally based on the assumption that annual energy projections overall for the entire State of NSW and the ACT can be used to inform local transmission planning decisions for a specific region. This is akin to saying the population of NSW is growing across each region at the same rate, rather than planning specifically for Sydney or Taree as the case may be.”
It goes on to list a number of areas where it says the Manning Alliance’s statements are misleading. These include its descriptions of TransGrid’s annual energy forecasts and maximum demand forecasts.
TransGrid says the facts on its maximum demands forecasts are: “TransGrid requests and publishes 10 year forecast information from local electricity distributors such as Essential Energy, Ausgrid and Endeavour Energy; who have direct relationships and local knowledge of electricity usage patterns and demand drivers by end-users in each region. TransGrid acknowledges that peak summer demand has been extremely volatile in the Mid North Coast over recent years, that is why TransGrid deferred the Stroud to Lansdowne Project until the early 2020s in June 2012, with the publication of the 2012 Annual Planning Report.
“TransGrid is undertaking a review of the timing and scope of works of the Project with Essential Energy, this review is scheduled for completion in September 2012. The review includes consideration of alternatives such as embedded generation and demand management, in addition to two transmission line options. This information is contained within the Annual Planning Report 2012.”
