Medium voltage - i.e. large commercial centres 

Substation between medium voltage and low voltage

Low voltage (i.e. residential network)

High voltage transmission network

Baseload generators are able to ramp quickly, such as hydro power, meeting high demand during (for example) heatwaves

Baseload is the minimum demand over a period of time, that the market can best meet with generation that provides constant output

Baseload describes the increase in demand on a typical day when conditions are mild

Baseload is the name given to generators that have constant output

Victorian energy companies had built new coal and gas fired power stations in recent years, increasing supply

There had been decreases in demand due to energy efficiency measures

There had been an increase in the uptake of rooftop PV

The heatwave in 2014 occurred in the middle of the week, when demand is typically lower

a & b

South Australia

Queensland

Victoria

Tasmania

All of the above

Creating incentives for PV owners to invest in batteries could alleviate grid congestion

Collecting revenue from PV owners to invest in the network is fair as the PV owners get the benefit of selling power into the grid

Creating incentives to reduce export onto the grid during peak times will help maximise the benefits of existing PV

Inertia

a, b and c

Record uptake of rooftop PV is reducing net demand

Answers a, b and c

The market operator needs to have some large-scale, dispatchable generators running above their minimum output
