FAQ

What is an inverter-based resource NERC?

NERC uses the term “inverter-based resource” to refer generally to BPS-connected facilities that have a power electronic interface between the ac grid and the source of electricity. An inverter-based resource (IBR) is a source of electricity that is asynchronously connected to the electrical grid via an electronic power converter (“inverter”).

What are examples of inverter-based resources?

Battery energy storage is also considered an inverter-based resource. Many transmission-connected reactive devices, such as STATCOMs and SVCs, are also inverter-based. Similarly, HVDC circuits also interface with the ac network though converters.

What are the benefits of inverter based resources?

Advantages

• Cost savings: Using systems powered by inverters can potentially lead to cost savings.
• Reliability and efficiency: Depending on the type of inverter used, inverters can supply high levels of reliability and efficiency, so users never have to worry about their electricity or power levels.

STATCOMs

A STATic synchronous COMpensator (STATCOM) is a fast-acting device capable of providing or absorbing reactive current and thereby regulating the voltage at the point of connection to a power grid. It is categorised under Flexible AC transmission system (FACTS) devices.

Decarbonization

What Does Decarbonization Mean?

‘Decarbonization’ tends to refer to the process of reducing ‘carbon intensity’, lowering the amount of greenhouse gas emissions produced by the burning of fossil fuels. Generally, this involves decreasing CO2 output per unit of electricity generated.
