Electricity generation From the mid-1920s, the town was supplied with
direct current electricity, which changed to
alternating current in 1948. Electricity was generated at the
Playford B (240 MW) and
Northern power stations (520 MW) from
brown coal mined at
Leigh Creek, 250 km to the north. The only coal-fired electricity generating plants in South Australia, in 2009 they produced 33% of the state's electricity, but over 50% of the state's CO2 emissions from electricity generation. Playford B has not been operational since 2012. In October 2015, Alinta Energy announced the permanent closure of both Northern and Playford B in early 2016. The Northern Power Station went offline in May 2016. In 2016, a local community group was lobbying for assistance to replace the coal-fired plants with a solar thermal power station. The
premier of South Australia,
Jay Weatherill announced in August 2017 that construction would begin in 2018 and was expected to be completed in 2020. The
Aurora Solar Thermal Power Project is expected to cost to build, including a loan from the Federal Government, and deliver 150MW of electricity.
SolarReserve has a contract to supply all of the electricity required by the state government's offices from this power project.
Arid-zone horticulture Separately,
Sundrop Farms has a combined
solar power tower,
greenhouse and
desalination plant which is used to produce tomatoes near the old power station site. It opened in October 2016 and produces 39MW of thermal energy from over 23,000 mirrors and a tower, used for heating, electricity, and desalination to irrigate tomatoes in greenhouses. Sundrop has a 10-year contract to supply
Coles Supermarkets with at least 15,000 tonnes of truss tomatoes per year.
Tourism Port Augusta has been able to capitalise on the growing eco-tourism industry due to its proximity to the
Flinders Ranges. The
Pichi Richi Railway is a major drawcard, connecting Port Augusta to
Quorn via the Pichi Richi Pass. Within Port Augusta is the
City of Port Augusta's Wadlata Outback Centre, providing tourists with an introduction to life in the Australian outback. The centre recorded over 500,000 visitors in 2006. North of the town, on the Stuart Highway, is the
Australian Arid Lands Botanic Garden, a unique and award-winning garden, opened in 1996, which "showcases a diverse collection of arid zone habitats in a picturesque setting of more than 250 hectares". The gardens have a cafe/restaurant with views across the saltbush plains to the escarpment of the Flinders Ranges. The PACC annual report shows more than 100,000 people visited the gardens in 2006. Southwest of town is the El-Alamein army base.
Proposed multi-commodity port In February 2019, the site of the former Playford power stations was sold by
Alinta Energy to
Cu-River Mining as a prospective port development site. The company intended to construct a transshipment facility suitable for the export of iron ore, wheat and other commodities. ==Media==
