Hydro Lake Level Data

Posted: June 27th, 2009 | Author: barnaclebarnes | Filed under: Dataset | Tags: , , | No Comments »

OPUS International has prepared a report “Lake level history” for the Commission which provides a brief history of the fluctuations in the levels of the major lakes used for hydropower generation in New Zealand. The lakes covered are Ohau, Tekapo, Pukaki, Te Anau, Manapouri, Hawea, Wanaka, Wakatipu, Taupo and Waikaremoana. The report describes the recording equipment used to measure levels and provides some guidance on how to interpret the data.

The report is accompanied by a dataset which includes average daily lake levels for the entire length of record available. These data have been obtained from the Power Archive, which is maintained by OPUS International under contract to the various power generation companies.

The Commission thanks Genesis Energy, Mighty River Power, Meridian Energy, and Contact Energy for supporting the project and providing data.


Electricity Commission Centralised Dataset

Posted: June 27th, 2009 | Author: barnaclebarnes | Filed under: Dataset | Tags: , | No Comments »

The Electricity Commission is required to establish, maintain, and publish a Centralised Dataset (CDS) under Part F of the Electricity Governance Rules.

The purpose of the Centralised Dataset is to support efficient planning processes by ensuring the collection and maintenance of historical information required to make decisions on transmission and transmission alternatives.

The Centralised Dataset includes:

Half – Hourly Data
Meter data

HVDC flows
Active power by grid exit point
Reactive power by grid exit point
Generation by grid injection point
Bids and offers

Prices

Final prices
Binding constraints

Hydrology data
Historic hydro inflows (New Spectra Update to end of June 2008 now available)

Historic lake levels (new report)

Network configuration data
Transmission network
System load flow models
PSS/E
DigSilent
Line diagrams
Circuit breaker information
Circuit breaker ratings
Bus fault levels

The Commission will maintain a register of recipients of the Centralised Dataset. The Commission requires this information to:

Inform you of any future updates to the CDS
Record recipients of the CDS due to the sensitive nature and copyright status of some of the material.
Archived Centralised Dataset documents

Web interface

Casual users may prefer the Web Interface to the CDS. The Web Interface allows users to access summarised half-hourly data from the CDS with a simple query tool. It is free and does not require registration.

Energy Use 2002-2005 Report tables

Posted: June 27th, 2009 | Author: barnaclebarnes | Filed under: Dataset | Tags: , | No Comments »

Energy is an essential element of any contemporary society and economy. Virtually all everyday activities and productive processes involve energy in one form or another. Internationally, economies are extremely reliant on energy, especially in the form of non-renewable oil-based fuels, such as petrol and diesel.

Questions on where the available energy is being used, and how efficiently it is being used are becoming increasingly important, as governments plan their energy futures. The focus of recent strategies is on tackling carbon emissions by increasing the uptake of low-emission technologies, such as electricity generation from renewable resources.

This report presents measures of energy use (in petajoules) and economic performance (in constant price GDP) at a national and industry level. The information presented in this report identifies where and how efficiently energy is being used in New Zealand’s economy.
