The Alternative Technology Association’s (ATA) Consumer Guide to Smart Meters helps households and small businesses understand and take advantage of products and services associated with smart meters. The guide provides easy-to-understand information. Some of the smart meter products and services exist now, and some are expected to become available in the next two to three years.

From It’s time for a smarter grid by Giles Parkinson:
Imagine for a moment that you are the head of a large group of network operators, faced with a decision about what to do about rising peak electricity demand. And you are presented with a choice: invest $2.6 billion over five years on upgrading your network – the route you would normally take; or spend a comparable amount on solar power and energy storage, distributed throughout the network. This was the question posed by Professor John Bell, of the Queensland University of Technology, and Warwick Johnston, a leading solar analyst with Sunwiz, when they sought to find out if there was a better way than the traditional response of building more poles and wires to cope with rising peak demand.
Using Queensland network operator Energex as an example, and its forecast peak demand growth of 1.25GW over the five years to 2014/15, the study analysed the existing approach of spending $2.6 billion augmenting the grid, or investing a comparable amount in either 25GWh of storage, or 1.25GW of solar PV and 10GWh of storage. The study concluded that a combination of battery and solar PV produced a far better outcome, because of the ability to generate revenue from the energy produced, and the use of battery storage to resell energy. Over a five year period, the net present value (NPV) of the poles and wires solution was negative $2 billion, while the NPV of the solar/storage solution was negative $750 million. But because these could produce revenue over a 20-year period, the solar/storage had a positive NPV of $2 billion over a 20 year period.
Bell and Johnston say the main take-home messages from this are that the integration of distributed PV and battery storage into the existing energy system has the potential to be cost effective now, and it underpins the case for reform of the National Electricity Market, to ensure that distributed generation is fairly treated and that network providers are encouraged to opt for the solutions that have greater market benefit, rather than simply being least upfront cost.

Effective and efficient transmission of electric power from generators to consumers is a vital part of the electricity system. Australia’s national transmission network is the longest AC system in the world, extending 5000km from Queensland to Tasmania to Port Augusta, supplying 19 million residents. As demand continues to grow and the penetration of renewables on the grid increases, the national transmission network will require significant extensions and upgrades. But what is the optimal design to support a very different energy system in the 21st century? Variable and distributed generation and potential large storage systems (such as an electric vehicle fleet) make this a diabolical question that the panel of experts will address in detail.

In 2007, 2.2 million people took part in the world’s first Earth Hour in Sydney Australia. Just one year later, 50 million people in 370 cities and towns, in more than 35 countries worldwide switched off their lights for Earth Hour.
Earth Hour 2009 aims to reach more than one billion people in 1000 cities around the world, inviting communities, business and governments to switch off lights for one hour at 8:30pm on Saturday March 28 and sending a powerful global message that we care enough about climate change to take action.
