AEMO : Australian Energy Market Operator. Manager of the NEM

AEMC :  Australian Energy Market Commission. Rule maker for the electricity and gas markets

ASIC : Australian Securities & Investments Commission

ASX : Australian Stock Exchange


Baseload power : The minimum level of power generation required, supplemented by peaking power as needed


CEC : Clean Energy Council – peak body for clean energy in Australia

CEFC : Clean Energy Finance Corporation. Australian Government-owned ‘Green Bank’ established to facilitate increased flows of finance into the clean energy sector. Invests commercially to increase the flow of funds into renewable energy, energy efficiency and low emissions technologies. Read more on their website here:

CHP : Combined Heat and Power. See Co-generation

Co-generation : Also known as CHP (Combined Heat and Power).  The use of a system that converts heat, thermal energy or a power station to generate electricity and heat at the same time.


DER : Distributed Energy Resources. For example battery storage, demand response, standalone power systems, micro grids.

Dispatchable Power : Power available on-demand as required


ENA : Energy Networks Australia – the peak national body representing gas distribution and electricity transmission and distribution businesses in Australia.

Energy density : is the amount of energy that can be stored in a mass of a substance or system. Colloquially it may also be used for energy per unit mass, though the accurate term for this is specific energy. The higher the density of a substance the more energy can be stored.

EPA : Environment Protection Authority – state government authorities

ERS : Energy Recovery System

ESS : Energy Storage Systems


FCAS : Frequency Control Ancillary Services

FFR : Fast Frequency Response or Firm Frequency Response

Frequency : Refers to number of cycles per second


GAS-TESS : 1414 Degrees’ Thermal Energy Storage System (GAS-TESS) uses world-leading technology to generate heat and store energy generated during wastewater treatment. GAS-TESS stores biogas as latent heat in molten silicon at 1414° Celsius, enabling it to produce electricity on demand, as well as a stable, consistent source of heat.

The GAS-TESS project at SA Water’s Wastewater Treatment Plant is an example of how this technology can be harnessed to put biowaste to productive and sustainable use. It will deliver heat energy as hot water for SA Waters’ digesters and electricity for general operations, and thereby increase the plant’s energy self-sufficiency. This project demonstrates the potential of biogas as a reliable and stable source of energy, and thermal energy storage’s ability to make renewables more cost-effective across many different industrial applications.


IEA : International Energy Agency


kW : Kilowatt – a thousand watts

kWh : Kilowatt hour – used to describe production/consumption or storage capacity


Latent Heat : Latent heat is energy that is held in phase change materials when it becomes molten. 1414 Degrees uses silicon which has a very high melting point, 1414 degrees Celsius. This means it can hold much more energy than other phase change materials, such as molten salt which has a latent phase at approximately 220 degrees.

LCOE : The levelised cost of electricity (LCOE), also known as Levelised Energy Cost (LEC), is the net present value of the unit-cost of electricity over the lifetime of a generating asset. It is often taken as a proxy for the average price that the generating asset must receive in a market to break even over its lifetime.

LRET : Large scale Renewable Energy Target. A scheme run by the Australian Government Clean Energy Regulator to promote the growth of renewable power generation.


MW : Megawatt – a million watts

MWh : Megawatt hour – used to describe production/consumption or storage capacity


NEM : National Electricity Market (Australia)

Non-synchronous (Renewable energy, such as solar and wind) : Clean energy sources are inconsistent, and have limited ability to react to changing demand. Unexpected weather changes also can stress the electricity grid’s constant balancing act. Storage devices can help overcome this.


Off grid : a power installation which has no connection to an electricity grid

OTR : Office of the Technical Regulator


PCM : Phase Change Material

Peaking generators (rapid-response gas and diesel generators) : These high-cost generators spend most of their time sitting idle. They wait until the energy grid shows signs of an unbalancing strain on supply, such as a heat-wave or generator failure. They jump into the market in an attempt to meet this shortfall.

PPA : Power Purchase Agreement

PV : Photovoltaic.  The conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon of the creation of electricity in a material upon exposure to light. Power output is dependent on direct sunlight.


SAPN : South Australian Power Networks

Stored energy : The energy available in a storage system to perform physical work through the conversion of its chemical or mechanical energy, stated in kWh or MWh

Stability : The ability of an electric system to maintain a state of equilibrium during normal and abnormal conditions or disturbances

Smart grid : Collectively; devices, practices and protocols that enable rich monitoring and situational awareness and flexible and robust control of various parts of or entire power systems under varying conditions. Among other objectives, Smart Grid is expected to reduce peak demand, increase energy efficiency and increase electric service reliability and power quality.

Spilled energy : Energy that is generated from renewable sources that is unable to be used, typically dissipated through a resistor bank. Also includes potential energy generation that has been restrained, i.e. braking of wind turbines to limit generation.

Synchronous : Traditionally energy provided by thermal power plants such as gas or coal. If more power is needed, more is burnt, but adequate warning is needed to meet large variations in demand. On their own renewables cannot provide synchronous power. The 1414 Degrees Tess can provide synchronous power, and therefore when paired with renewables, enables clean synchronous power.


TES : Thermal Energy Storage

TESS : Thermal Energy Storage System


Watt : A unit of electrical energy. A watt is defined as energy consumption rate of one joule per second.
