Energy Exchange Reverse Auctions

Since launching in August 2016, the Energy Exchange has run reverse auctions covering a range of site types and sizes, proving its ability to deal with the wide range of needs typical of many larger electricity consumers.

What drives electricity prices?

What drives electricity prices? Demand? Fuel costs? Losses? Transmission constraints? Carbon costs? The cost of new generation? Inflows? Well they all have an impact to a certain degree. The time frames vary but the answer in the long run is surprising, especially given that we are currently running at over 80% renewable generation.

Back-casting 2016

One of the many challenges for anyone forecasting electricity spot prices, as Energy Link has done since first trading in 1996, is that some key factors affecting spot prices are fundamentally unpredictable in the short to medium term: inflows to the hydro lakes are a case in point.

2016 in Retrospect

Over the last 20 years, spot prices in the electricity market were highly volatile. But 2016 will be remembered as one of the least volatile years on record.

Energy Link’s January 2017 Price Path

This week we released our latest quarterly Price Path, a long term forecast of spot prices, to our subscribers. 2016 has indeed been an uneventful year on the spot market, a function of a warm winter and lots of rain for generation and for pastures. However, the last quarter delivered up some very significant news on the gas front.

Futures Efficiency and 100% Renewables at the OERC Symposium

The 10th annual Symposium of the Otago Energy Research Centre (OERC) was held in Dunedin on 10th and 11th November. I presented at the conference, and Fergus Bevin-McCrimmon gave a presentation of the results of his research on the efficiency of electricity futures markets. Energy Link was very pleased to sponsor the prize for the best student presentation, won by PhD candidate Paul Crane for his presentation titled “Helping Support Energy Management Systems at the University of Otago”.
