Finkel review

Jacobs Group modelling suggests clean energy target is also more expensive than an energy intensity scheme

Released today, five days after the report itself, the economic models that inform the report reveal the main thing the policy achieves is giving some confidence to power generators — including coal power stations — so they can make informed decisions about investments. Alan Finkel commissioned Jacobs Group to do the emissions modelling. Their report shows that “business as usual” would result in emissions from the electricity sector falling in the years to 2030 — but not quite enough to meet the target that Finkel has set of 28% below 2005 levels. Those cuts are driven by the existing renewable energy target, which runs until 2020, and then by the closure of existing coal-fired power plants as they reach the end of their life. By instituting the clean energy target (CET), the modelling suggests emissions will fall more steadily, and will reach 28% — but that is only a little below what would be achieved by doing nothing.

Under business as usual, coal generation would drop suddenly by 2045 to a figure not seen until 2050 under the CET. However, under the CET, the reduction in coal generation would reduce gradually over the entire period, rather than drop suddenly in the 2040s.

Underlying all this, the modelling also reveals that the CET, which Finkel recommended, is more expensive to the economy overall than the alternative approach — an emissions intensity scheme, which has been backed by almost every industry group as well as Labor. “The lowest-cost options for the policy scenarios are for an EIS scheme, followed closely by the CET scheme,” the Jacobs modelling paper says. The finding comes despite the energy and environment minister, Josh Frydenberg, saying on Wednesday on ABC Radio National that the emissions cut “has to be done before 2030, but it should be done with the lowest cost of abatement.” In the report, Jacobs found the CET had a cost of abatement about 30% higher than an EIS — with each tonne of CO2 costing $10.50 to abate under a CET, rather than $7.50 under an EIS.
