The report, authored by Hugh Saddler, notes that for nine of the last 18 months, half of all electricity supplied in S.A. has been from renewable generators, including rooftop solar.This renewable generation has at times been enough to meet all of the state’s energy demand and – as AEMO has acknowledged – will be able to gradually reduce market interventions such as directing gas generators to run as more synchronous condensers come on line.“South Australia is showing Australia and the rest of the world how best to integrate new generation on a large scale,” says Saddler. “The inter-connector between South Australia and Victoria was completed more than 30 years ago, and since then South Australia has almost always been a net importer of electricity from Victoria. Now, thanks to its strong renewables leadership and uptake, it is a net exporter of electricity to Victoria for most months of the year.”“Eliminating ‘base load’ is what the transition to a low emission renewable generation based electricity supply system is doing,” the report says; “in South Australia, in the rest of Australia, and round the world. The complement to variable renewable generation is not so-called “base load” generation (a meaningless term), but energy storage in some of its many forms and spatial/climatic diversification of renewable generation.”More: South Australia “an example to the world” of how to move beyond baseload Analysis says South Australia is setting an example for renewable energy transition
The veteran striker’s move to Sampdoria was confirmed on Tuesday and Martinez sees Arouna Kone, who is fit again after a long-term knee injury, as the player to step into the breach. Everton are enduring a difficult season and have failed to win any of their last eight games, but Martinez is in no hurry to bring in reinforcements. He told the club’s official website: “January is not the place to find solutions (in the transfer market). Our moment of form, we want to change, but the solutions are in the squad. “With Arouna Kone being fully fit, I see him as a replacement for Samuel’s position and it is more about trying to get the players back from injury. “Steven Pienaar and Leon Osman have been two players missing throughout the season, which has been disappointing because they are important in the way we want to play. “Leon played in every single game last season and we miss what he brings. So I am looking around that. “We are always working and if we can do something to help the players we have got at the club then we will do something. But what’s clear is that January is not very straightforward. “You never get value for money, first and foremost, and you will not get players you have been following for a long time. And if you want to rely on January to find solutions for your season, then it is a big gamble.” Press Association Everton boss Roberto Martinez is not looking to sign a replacement for Samuel Eto’o during the January transfer window.
