Rooftop solar capacity to double or even triple to replace existing thermal generation, new assessment by the energy market operator predicts

Australia’s ageing coal-fired power plants could be shuttered earlier than expected if competition from renewable generators and carbon budgets render them uneconomic, according to a new assessment by the Australian Energy Market Operator.

Aemo will, on Thursday, publish a new draft integrated system plan which snapshots the unfolding revolution underway in Australia’s energy market. The energy market operator predicts rooftop solar capacity will double or even triple, providing up to 22% of total energy by 2040.

Energy park of one or more islands would be able to supply up to 10 million households

Denmark is pursuing plans to build one or more artificial islands surrounded by offshore wind turbines with a capacity of 10 gigawatts, capable of supplying up to 10 million households, the climate and energy ministry has said.

The country, which produced 41% of its energy from wind power in 2018, the highest level in Europe, last week passed an ambitious climate act which commits it to cut greenhouse gas emissions to 70% of 1990 levels by 2030 and achieve carbon neutrality by 2050, with new, legally binding targets every five years from 2020.

Australian Energy Market Commission says prices will begin to fall next year and by 2022 will be $97 a year lower

The price of residential electricity is estimated to start falling next year and continue to fall until 2022, the Australian Energy Market Commission says.

The AEMC’s annual report on electricity price trends shows an overall falling price outlook over the next few years, mostly due to decreases in the wholesale cost from increased generation capacity, particularly from windfarms.
