Queensland switches back to coal

February 5, 2014

Once upon a time Australia had among the lowest electricity costs in the world but that was in the days where the market was not distorted by carbon taxes, mandatory renewable energy targets and subsidies for solar power. Coal prices are declining while gas prives are rising. This from The Australian as Queensland goes the way of Germany:

QUEENSLAND’S largest power generator will today declare that Australia is one of the world’s most expensive countries for energy and warn that the electricity market is being distorted by the carbon tax, mandatory renewables target and solar-rooftop subsidies.

After Stanwell took the extraordinary step yesterday of announcing it would mothball its biggest gas-fired power station and resurrect a coal facility built in the 1980s – sparking predictions that gas-fired power plants would be withdrawn in other states – it will today call for a scaling back of the renewable energy target.

Before the introduction of the carbon tax, the RET scheme and solar feed-in tariffs, the abundance of coal had made Australia a source of low-cost electricity, the company will say. “These policies appear to have been implemented for ideological reasons with little analysis of the impact on electricity prices and economic growth,” Stanwell chief executive officer Richard Van Breda will say.

Stanwell will issue its warnings as part of its submission to the federal government’s energy white paper, being developed by Industry Minister Ian Macfarlane.

The submission will caution that a raft of energy policies is eroding Australia’s competitiveness in manufacturing, which is a sensitive issue for the government amid internal tensions over taxpayer handouts to businesses, including SPC Ardmona.

Yesterday, Stanwell revealed it would withdraw its Swanbank E power station, near Ipswich west of Brisbane, from service for up to three years from October so it could sell the gas rather than use it in electricity generation. …….. A unit at the Tarong coal power station – in cold storage since late 2012 – will be returned to service later this year.

….. Germany is shifting back to more coal-fired electricity generation, reopening some of its dirtiest brown-coalmines that have been closed since reunification, despite having spearheaded Europe’s push into renewable energy. China has plans to add another 860 million tonnes of coal production by 2015. ………  

Stanwell’s energy white paper submission will raise concerns that the surge in rooftop solar panels has increased the capacity of the market, making cheaper coal-fired power stations run less efficiently. It says solar feed-in tariffs (state government schemes) have resulted in high ongoing costs for network infrastructure. …

 

Wind Power Sector struggles

August 21, 2010

Wind Power is still a long way from being commercial and is  still critically dependent upon subsidies. Austerity packages resulting from the financial crisis have sharply reduced subsidy programs and there have been a spate of cancelled and delayed projects. There is also some disillusionment evident as wind turbines demonstrated their weaknesses during the last cold winter when many had to be shut down in Europe for fear of ice on the turbine blades. The requirement for back-up power and the instability they add to the grid has not helped either. The Spanish support for renewables has dried up as the financial crisis has hit hard.

An injection of realism and common sense to the the use of renewable energy is long overdue. Wind and Solar and tidal and geothermal energies all have their place but they will not – and cannot – provide the base load power generation that coal, nuclear and hydro power have provided.

The FT reports that shares in Vestas Wind Systems lost more than a fifth of their value on Wednesday after the world’s largest wind turbine manufacturer slumped to its second consecutive quarterly loss and cut its profit guidance for the year.

Vestas warned that some expected orders from Europe and the US had been delayed as banks take longer to approve financing and deficit-laden governments review their support for wind power. Analysts highlighted regulatory uncertainty in Spain, which recently cut subsidies for renewable energy as part of its fiscal austerity programme, and the US, where legislation to promote clean energy has stalled on Capitol Hill. Low natural gas prices, caused in part by the surge in supplies from newly exploited US shale gas reserves, was another factor deterring investment in more costly renewable energy, analysts said.

New wind power installation in the US declined by more than two-thirds in the first half and fell below new coal power capacity for the first time in five years.
