5 September 2016, Renew Economy, One small gain for battery storage, one big win for fossil fuel industry. Australia’s principal policy maker for the energy markets has waved through a rule change that could accelerate the use of battery storage to provide grid stability as more renewables enter the market. But the rule maker has shocked participants with another decision that may reinforce the dominance of the big fossil fuel utilities. The Australian Energy Market Commission late last week made two rulings that it was first asked to consider way back in 2012 (such is the glacial pace of change in Australian regulatory circles) but which seen as critical as more wind and solar enter the market and old fossil fuel generators are phased out. One of the rulings was good news and largely expected: The AEMC said it would allow “unbundling” of ancillary services for the grid – which provide fast-acting balancing responses following a “contingency” event, usually the unexpected loss of a large thermal generator. This means that these services, known as FCAS, can now be more easily provided by more players, and not just the big generators, which currently control the supply (and thus the price) of FCAS services. Allowing new players like batteries and demand response loads should increase the supply of FCAS, and lower market prices. That ruling was largely uncontroversial and expected, with any opposition by incumbents lukewarm at best. The second ruling, however, has stunned some participants in the industry, because it effectively limits the amount of battery storage and new ideas – such as aggregating power plants in homes – by leaving it in the control of the major players. The proposal was to create a “demand response” mechanisms in the spot market to respond to times of high load, and high electricity prices, as were experienced in South Australia and other states in recent months, and which used to be frequent years ago, and may well become regular again as gas prices rise.
