SYDNEY/SINGAPORE, Feb 4 (Reuters) - Australia is on the verge of a boom in renewable energy projects but lack of spending on power lines and an indifferent regulatory environment threaten to hamper even greater investment.
Analysts and industry officials say billions are expected to be spent between this year and 2020, with most of the money going on wind farms, which are the least costly option, versus coal and gas, as Australia cracks down on greenhouse gas emissions.
Solar power also holds promise in a country known for its sunshine and, further out, wave power and geothermal will also probably see increased investment.
New transmission lines will be needed as windfarms and other renewable projects are built. But unless regulatory hurdles are overcome, some potential investors will steer clear, leaving the country struggling to meet a mandatory renewable energy target (MRET) of 20 percent green power by 2020.
"The MRET will drive around A$20 billion to A$30 billion, or 11,600 megawatts (MW) of new capacity, between now and 2020," said Sean Lucy, head of nabCapital's Carbon Solutions Group in Melbourne, which is investing in wind farms.
The MRET has been enshrined in legislation released for public comment until Feb 13. A national emissions trading scheme from mid-2010 will also help drive investment because it will put a price on big coal-fired power generators' carbon emissions, making greener power more attractive.
"We're expecting to see significant investment in 2009," Lucy added, referring to three wind power projects totalling 711 MW in development or construction.
Industry body the Clean Energy Council also sees major investment if the renewable target legislation is designed correctly, Chief Executive Matthew Warren said.
"There's an immediate response if and when that legislation is finally passed by parliament this year," he said, echoing Lucy's view that billions of dollars would be invested.
CONSERVATIVE
But a study by economics consultancy firm ACIL Tasman found that to reach the 20 percent target, more than 4,000 MW of new wind generation and an anticipated 1,500 MW of new geothermal capacity would be needed. This would require at least A$4 billion of additional investment in electricity grid infrastructure.
Energy Supply Association of Australia acting chief executive Clare Savage says ACIL Tasman's estimates are likely to prove conservative but attracting investment could prove difficult because of proposed regulatory changes.
Savage said a move by the regulator of Australia's national electricity market to lower the returns on energy infrastructure investments could derail projects aimed at feeding renewable energy into the national grid.
In a draft decision late last year, the Australian Energy Regulator moved to lower cost of capital assumptions used to calculate "the adequate" return that determines prices charged by the owners of energy transmission networks.
"Like anything else, to attract investment you need adequate returns but we've got the regulator wanting to lower returns on energy infrastructure," said Savage in an interview.
More than 80 percent of Australia's electricity is generated using black and brown coal, with a further 12 percent from natural gas. Less than 7 percent comes from renewable sources.
A government report says total energy consumption is expected to rise 19 percent between 2009/10 and 2019/20 and by 40 percent over the next two decades, driven largely by manufacturing, mining, transport and a rising population.

The government is establishing a A$500 million renewable energy fund to boost investment in the sector but billions more are needed from the private sector to reach the MRET goal.
The renewable energy target will be driven by the existing Renewable Energy Certificate scheme, in which green power producers receive a REC for each megawatt/hour produced.
Under the scheme, electricity retailers must buy RECs in proportion to the amount of energy they sell. RECs were selling for A$50.50 on Wednesday.
WINNERS
Winners from MRET are likely to be wind farm developers, such as Pacific Hydro and Roaring40s, and equipment makers such as India's Suzlon as well as solar water heater and panel makers.
Generators such as Origin Energy and AGL Energy also stand to gain because green energy investments will cut their carbon emissions under the emissions trading scheme.
"There will be an extraordinary amount of investment and there are a lot of companies that are positioning to make that happen," said Lucy, adding that a lot of Australia's wind resource was still untapped.
One of the largest windpower commitments to date has been made by Spanish firm Union Fenosa, which plans to invest US$1.2 billion developing seven wind farms in southeast Australia.
On completion in 2013, the seven wind farms will add 850 MW of generation capacity.
AGL Energy, Australia's largest energy retailer, also plans to be major player in the renewable energy sector, committing more than A$2 billion to wind and hydro generation projects.
But analysts and industry officials say lack of investment in transmission lines will still hold up some projects.
"We have some wind farm opportunities that just sit in limbo at the moment that we would love to develop but we can't because the network capacity is not there," said Lane Crockett, general manager, Australia/Pacific, for Pacific Hydro, which invests in wind and hydro.
The unlisted company, one of the country's largest green power producers, has about 800 MW of projects in the pipeline, of which 300 MW is either stranded or at risk due to infrastructure.
"While we are hearing talk about connection issues in the market, it is not currently impacting our deal flow," said Lucy of nabCapital.
In South Australia, for instance, the grid needs to be overhauled to allow proposed wind farms along the coast to be connected.
The state's north also has large potential for geothermal power generation but a lack of transmission lines to carry the power to New South Wales, Victoria and Queensland states has hobbled major investment.
"One of the best examples I can think of is to connect transmission lines from Queensland, South Australia to the East Coast grid interconnector and even the East Coast to the West over the Nullarbor Plain," said Barry Brook, director of the Research Institute for Climate Change and Sustainability at the University of Adelaide.
"By doing that you have provided a link by which a whole bunch of renewables can come on to the grid where it can't right now, and that it is one of the major limitations for investment," Brook said, calling also for greater focus on energy efficiency. (A$=64.7 U.S. cents)
