Grid Connected Microgrids

Microgrid benefits

Microgrids have historically been popular in remote areas like islands that are without access to a national electricity transmission network. Substantial cost reductions in solar PV and lithium-ion batteries are enabling clean energy microgrids to be built in cities.

Planet Ark Power is able to create a grid-connected microgrid. This enables major benefits including:

  • Economics are much improved through the ability to trade the spot market and engage in Frequency Control Ancillary Services (FCAS).
  • Improves grid security and stability by enabling participation in FCAS. With AEMO and state governments, like SA, encouraging distributed energy sources.
  • Enables the unlocking of other income streams from the connection of onsite diesel or gas generators that would otherwise be idle and only used for backup.
  • Provides the site with cheaper, cleaner power, at zero marginal cost, unlike other energy sources such as gas.
  • Power security through islanding capability as the battery and the solar can come on to power the site almost instantly ensuring no loss of power continuity

Planet Ark Power Microgrid - Adelaide SA

Planet Ark Power is expected to install a very large Microgrid in 2020

  • 1.21 MW of rooftop solar + 3.0MW (3.4MWh) lithium-ion batteries stacked in 3 x 40ft on-site containers with an additional 20ft container for specific demonstration of eleXsys® and VAR control for the network.
  • Excess solar energy (.31MWh*) is stored in the batteries and then sold to the network at optimal times via FCAS & spot- market trading.
    NB: without eleXsys this would not be economically viable.
  • This project will help prove the scalability of the solution.
