How we plan the network

Review of need drivers to inform decisions

Typically when updated forecast become available

Less frequently other factors such as changes to

Generation

Capability and performance of the existing network


A shift in focus for capital works


Demand Management – Our commitment

TransGrid is committed to delivering cost-effective non-network

options

These options can defer or avoid investment in the electricity

transmission network, delivering benefits to consumers.

Investment in innovation is crucial in order to unlock the full potential

of demand management in NSW.

TransGrid is proposing to invest $18 million in demand management

innovation from 2014 to 2019.

Transmission Annual Planning Report

The Transmission Annual Planning Report is a key output from

the NSW Annual Planning Review, the central vehicle by which

TransGrid provides an assessment of the capabilities and

constraints of our network for the upcoming 10 year period.

The 2014 Transmission Annual Planning Report includes:

outcomes of the annual planning review including planning analysis

of network capabilities and constraints, and potential solutions within a

10 year planning horizon;

completed, committed and planned projects;

energy and demand forecasts;

network replacement projects; and

opportunities to collaborate with providers of non-network solutions.
