Query: When South Australians buy electricity at $14,200/MWh, they are paying the equivalent of $400 a litre for petrol.

Relevant passages:
Kilowatt hour <=SEP=> The kilowatt-hour ( symbol kWh , kW ⋅ h or kW h ) is a derived unit of energy equal to 3.6 megajoules . If the energy is being transmitted or used at a constant rate ( power ) over a period of time , the total energy in kilowatt-hours is the power in kilowatts multiplied by the time in hours . The kilowatt-hour is commonly used as a billing unit for energy delivered to consumers by electric utilities .

Energy policy of India <=SEP=> The energy policy of India is largely defined by the country 's expanding energy deficit and increased focus on developing alternative sources of energy , particularly nuclear , solar and wind energy . India ranks 81 position in overall energy self sufficiency at 66 % in 2014 .   The primary energy consumption in India is the third biggest after China and USA with 5.3 % global share in 2015 . The total primary energy consumption from crude oil ( 195.5 Mtoe ; 27.91 % ) , natural gas ( 45.5 Mtoe ; 6.50 % ) , coal ( 407.2 Mtoe ; 58.13 % ) , nuclear energy ( 8.6 Mtoe ; 1.23 % ) , hydro electricity ( 28.1 Mtoe ; 4.01 % ) and renewable power ( 15.5 Mtoe ; 2.21 % ) is 700.5 Mtoe ( excluding traditional biomass use ) in 2015 . In 2013 , India 's net imports are nearly 144.3 million tons of crude oil , 16 Mtoe of LNG and 95 Mtoe coal totalling to 255.3 Mtoe of primary energy which is equal to 42.9 % of total primary energy consumption . About 70 % of India 's electricity generation capacity is from fossil fuels . India is largely dependent on fossil fuel imports to meet its energy demands -- by 2030 , India 's dependence on energy imports is expected to exceed 53 % of the country 's total energy consumption . In 2009-10 , the country imported 159.26 million tonnes of crude oil which amounts to 80 % of its domestic crude oil consumption and 31 % of the country 's total imports are oil imports . By the end of calendar year 2015 , India has become a power surplus country with huge power generation capacity idling for want of electricity demand . India ranks second after China in renewables production with 208.7 Mtoe in 2014 .   In 2015-16 , the per-capita energy consumption is 22.042 Giga Joules ( 0.527 Mtoe ) excluding traditional biomass use and the energy intensity of the Indian economy is 0.271 Mega Joules per INR ( 65 kcal/INR ) . Due to rapid economic expansion , India has one of the world 's fastest growing energy markets and is expected to be the second-largest contributor to the increase in global energy demand by 2035 , accounting for 18 % of the rise in global energy consumption . Given India 's growing energy demands and limited domestic fossil fuel reserves , the country has ambitious plans to expand its renewable and most worked out nuclear power programme . India has the world 's fifth largest wind power market and also plans to add about 100,000 MW of solar power capacity by 2020 . India also envisages to increase the contribution of nuclear power to overall electricity generation capacity from 4.2 % to 9 % within 25 years . The country has five nuclear reactors under construction ( third highest in the world ) and plans to construct 18 additional nuclear reactors ( second highest in the world ) by 2025 .

National Electricity Market <=SEP=> The National Electricity Market ( NEM ) is the Australian wholesale electricity market that covers the electrically connected states and territories of eastern and southern Australia , and the associated synchronous electricity transmission grid . The Australian Energy Market Commission develops and maintains the Australian National Electricity Rules , which have the force of law for the NEM in the participating states and territories . The Rules are enforced by the Australian Energy Regulator .   The NEM began operation on 13 December 1998 and operations currently cover the electrically connected states and territories of eastern and southern Australia of Queensland , New South Wales , Australian Capital Territory , Victoria , Tasmania and South Australia . Western Australia and the Northern Territory are not connected to the NEM . The NEM comprises five regions , with the ACT being in the NSW region . Tasmania joined the NEM in May 2005 and became fully operational on 29 April 2006 when the Basslink interconnector was fully activated . The Snowy region was abolished as a region on 1 July 2008 and the components split between New South Wales and Victoria . The Northern Territory has adopted parts of the National Electricity Law , with the Australian Energy Market Commission becoming the rule maker for the Territory for parts of the National Electricity Rules from 1 July 2016 . Western Australia is also considering adopting parts of the NER .   The NEM operates the world 's longest interconnected power systems between Port Douglas , Queensland and Port Lincoln , South Australia with an end-to-end distance of more than 5000 kilometres , and 40,000 circuit kilometres . Over A$ 11 billion of electricity is traded annually in the NEM to meet the demand of almost 19 million end-use consumers .

Solar power <=SEP=> Solar power is the conversion of energy from sunlight into electricity , either directly using photovoltaics ( PV ) , or indirectly using concentrated solar power . Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam . Photovoltaic cells convert light into an electric current using the photovoltaic effect .   Photovoltaics were initially solely used as a source of electricity for small and medium-sized applications , from the calculator powered by a single solar cell to remote homes powered by an off-grid rooftop PV system . Commercial concentrated solar power plants were first developed in the 1980s . The 392 MW Ivanpah installation is the largest concentrating solar power plant in the world , located in the Mojave Desert of California .   As the cost of solar electricity has fallen , the number of grid-connected solar PV systems has grown into the millions and utility-scale solar power stations with hundreds of megawatts are being built . Solar PV is rapidly becoming an inexpensive , low-carbon technology to harness renewable energy from the Sun . The current largest photovoltaic power station in the world is the 850 MW Longyangxia Dam Solar Park , in Qinghai , China .   The International Energy Agency projected in 2014 that under its `` high renewables '' scenario , by 2050 , solar photovoltaics and concentrated solar power would contribute about 16 and 11 percent , respectively , of the worldwide electricity consumption , and solar would be the world 's largest source of electricity . Most solar installations would be in China and India . Currently , as of 2016 , solar power provides just 1 % of total worldwide electricity production but growing 33 % per annum .
