Feed In Tariffs – The Devil Lies In The Details
Climate Change “is the greatest market failure the world has seen”
-Sir Nicholas Stern
This analysis and other similarly dire predictions have stimulated decision makers in many countries to consider new approaches to energy policy. The daunting challenge they face, has been to make the cost of renewable energy competitive with heavily-subsidised conventional energy. In the past, householders or energy companies who wanted to install wind turbines or solar panels have been faced with lengthy pay-back times. They have been forced to make a choice based on ethics rather than economics. Without increased consumer demand and political measures to facilitate access to the market, manufacturers of, for example, wind turbines and solar photovoltaic (PV) panels, cannot produce the unit volumes needed to bring prices down and drive technological innovation. (Access economics, 2008)
The Feed-In Tariff (FIT) has proven to be the most effective policy instrument in overcoming these barriers. Led by Germany and Spain this simple, relatively low-cost mechanism has turned several European countries into world leaders in the renewables sector. Under a feed-in tariff mechanism, eligible renewable electricity generators (which can include homeowners and businesses) are paid a premium price for any renewable electricity they produce. Typically utilities are obligated to take the electricity and pay them. (Bender et al, 2009).
Close to 75% of the world’s residential solar photovoltaic (PV) installations have occurred with the support of national, state or provincial FIT policies. (Solangi et al, 2011). In 2009, 45 countries and 28 states/provinces/territories had FIT programmes in place. (International Energy Association, 2010)
Gross or Net?
There are two metering options for solar PV FIT programmes: 1) net metering (also referred to as net export, or import/export metering), and 2) gross metering.
Under a net metering scheme, residential energy generators are paid for the net quantity of electricity exported to the grid after accounting for in-home consumption. In other words, Net Export = Gross Production - Household Load. Western Australia currently offers its incentive on a net export basis.
By contrast, under a gross metering system (as in the ACT and NSW), PV owners receive the premium tariff for all electricity produced by their systems (whether consumed at home or exported). They then pay the retail price for the electricity they actually consume.
It is interesting to note that gross FITs schemes appear to have become the worldwide default standard. Of the 45+ international examples of feed-in tariff schemes, Australia appears to be among the very few, if not the only country to adopt this form of metering for feed-in tariffs (McKinsey & Co, 2009)
The Consumer’s Perspective
Gross FIT schemes are widely believed to be a more effective policy instrument than Net in achieving customer uptake of solar PV renewable energy technology; (International Energy Agency 2010, World Futures Council 2008) for reasons that are discussed below.
Net Feed In Tariffs are not without their supporters, some of their arguments are outlined below;
In sum, net FIT schemes appear to lack several key attributes of successful consumer policy instruments. I.E. concrete, salient examples with cost/benefit information (Tversky and Kahneman 1974) designed to be as specific, detailed, and practical as possible (Stern 1976; Dresner 1990; Dennis et al. 1990) so as to allow participants to know the advantages and disadvantages of each measure and feel in control of their choices (Dennis et al. 1990).
Furthermore, with net metering this difficulty in gauging energy usage may actually serve to undermine the core purpose of FIT schemes, that is to stimulate energy conservation; as households using net metering cannot actually determine their own energy consumption, and therefore cannot use the meter to guide energy saving measures. (Pichert and Katsikopoulos 2007)
What are the others doing? - policies and responses worldwide
Ontario’s recently commenced renewable strategy and residential Gross FIT scheme is among the most ambitious globally. The provincial government is on track to close all its coal-fired power plants by 2014. The 694 large scale FIT contracts announced to date are expected to create 30,000 direct jobs and attract an estimated CAN $14 billion in private sector investment. (Pietruszko,2006)
In Germany, a Gross FIT program has been offered to PV operators since 2001. The success of the FIT along with solar PV purchase subsidies have enabled Germany to reach its goal of a 12.5% renewable energy supply three years early, in 2007. (Pietruszko,2008)
The rapid growth in Germany post 2004 (Figure 1) can be seen in response to a raft of new more attractive policies introduced in that same year. In Spain the first FIT scheme was launched in 2005 and then upgraded in 2007. (International Energy Association, 2008) In Japan meanwhile, between 1996 and 2007 subsidies of around AUS$2400 were allocated by the Japanese government for systems up to 10kw. With the conclusion of the subsidy programme, Japan did experience a reduction in demand from 290 MW in 2006 to 210 MW in 2007. (International Energy Association, 2008). Perhaps as a reaction to this drop in household demand for solar PV, the Japanese government instated a gross feed in tariff of AUS $80c/kwt in 2009 for residential solar generators.
Within the United States, California is recognised as one of the pioneering states in the adoption of FIT policy instruments for solar PVs. In an interesting format, generators can choose between a 10, 15 or 20 year contract and can opt for a gross FIT or Net Fit themselves.
Figure 1 also shows how Australia’s share of the solar PV market has fallen from around 7 per cent in 1992 to 1 per cent in 2007. (International Energy Agency, 2008)
If only! - Designing an optimal gross national FIT
Based on experience from overseas FIT schemes, and modelling by Access Economics; the Clean Energy Council PV Directorate (2008) maintains that FITs schemes should include the following principles:
It should be noted that within Australia, no state or territory deploys a FIT scheme with the aforementioned attributes.
