In 2008 the City of Sydney launched a master plan – Sustainable Sydney 2030- The Vision.
The goal is to reduce greenhouse gas emissions by 18 to 26% below 2006 levels across the entire City of Sydney by 2030. This is to be achieved by building a micro-grid within Sydney, using biofuel, mini-hydro, photo-voltaic (PV) solar arrays and tri-generation power plants.

In what ways can the concept of a micro-grid be applied to reduce costs and improve reliability?
The purchase of individual assemblies and devices without consideration
of the interconnection can lead to significant interface issues during
construction and commissioning.
The interface issues at site may be eliminated by an integrated approach
during the design phase.
For instance, different packages may be sourced from different suppliers, each with vendor specific standards. The vendor interface may suit the vendor but may not suit interfacing to other packages or to the central plant system.
The interconnecting cables may not be optimised and changes may be required for the interface to operate. Additional design time is required to prepare the interface as this will
not be part of the vendor’s scope. The need for additional design time may not be realised until late in the construction phase, when the design team may no longer have the resources to cope with the new demands. Additional cables may be required and on-site modification of vendor packages.
A different approach is to integrate the design of the vendor packages, interconnecting cables and systems interface during the design phase. For example, the interconnecting cables may be arranged so that the terminal strip for each cable is cable specific and all cores are terminated, including spares. Hard-wired interfaces may be arranged to suit the necessary signalling and switching requirements. Voltage and current supplies may be finalised.
In this way, interface issues at site may be eliminated, reducing site costs and allowing faster completion of commissioning. The interconnecting cabling may be optimised and the need for unforeseen additional cables to be installed eliminated.
The Buckeye Bullet team at Ohio State University is building a battery powered, electric vehicle that it hopes will be the first electric vehicle to exceed 400 miles per hour (670 km/hour).
The vehicle will be four-wheel drive and fitted with four electric motors each rated at 400 HP (total 1,600 HP). The power is provided by 80 flat “pouch” battery modules. Each module will hold 25 pouch cells. The pouch type batteries are a prototype iron nanophosphate lithium-ion battery from the manufacturer of A123 systems.
