Wait a minute. Increased decentralization of power generation _does_ make large network improvements neccessary. This does (in the case of Australia) not have anything to do with load, but with locality and network resilience.
The traditional electricity network is a bunch of interconnected star-shaped networks, each with a large power station in the middle. You now not only have to get bigger power lines to where the decentralized "power stations" are, but you also have to increase the overall interconnectedness, to avoid instability (think parts of the network going out of phase with other parts, localized overload and so on) due to the volatility of the renewables.
Unlike Australia, some countries with unevenly distributed renewables do indeed also have to massively increase their overland capacity (central Europe).
- whatusername 13y agoYes and no. As I understand it -- most of the network improvements are to do with Peak Load. (ie -- the days where it's 45 degrees C and every household is cranking A/C). Solar PV definately helps reduce those few days a year Peaks. In the Australian context -- as I understand it -- the Privatization of the Electricity Generators was such that they are legislated to only charge a fixed % of their costs. So the only way for them to make more money is to increase their cost-base (aka "Gold Plating") and then charge their customers the additional fees.
