#IRON GRIDS FOR FENCES HOW TO#

On the surface, iron-flow batteries seem like a solid solution to how to run an electricity grid dominated by variable renewables.īut to be deployed at scale they will need a supportive regulatory environment that will enable sufficient land, grid connections and economics that make sense to utilities. They also are too large for residential use, although if regulations were amended it's possible they could work on a neighbourhood basis, or in remote towns unconnected to the main grid. They do have some disadvantages, namely being they are much larger than equivalent capacity lithium units, meaning they need space to be installed. Parry also says iron-flow batteries work out about a third cheaper than lithium ion units when looking at the cost on a MWh basis. Parry doesn't see iron-flow batteries replacing lithium-ion units, rather they are complementary with lithium batteries able to arbitrage power prices by acting rapidly, while iron-flow units are more likely to act as baseload firming for the grid when renewables tail off. 'There hasn't been a need for them up to now, you need to see large-scale generators drop off,' he said.

With the retirement of coal-fired generators over the coming decade, iron-flow batteries can fill in the gap, Parry told Reuters in an interview on Oct. Iron-flow batteries can provide electricity for longer durations than typical lithium-ion alternatives, lasting up to 10 hours, meaning an 150 MW battery plant could power 50,000 homes overnight.ĮSI Managing Director Stuart Parry believes iron-flow batteries are an idea whose 'time has come.' The project plans to have a 150 MW battery in commercial operation by 2029.

The new code section requires fencing to be. Most substations are utility owned and therefore not covered in the NEC ® but once in a while, a substation is privately owned and the NEC ® applies. 5, also gives Stanwell the right to purchase up to 200 MW of storage a year from 2026. Section 250.194 is new in Part X of Article 250 and covers the grounding and bonding requirements for metal structures and fences near a substation. This comes in the form of 20 12-metre (39 foot) batteries that will be installed at the Stanwell power station in the Queensland regional city of Rockhampton.

However, Stanwell Corp, an electricity generator owned by the Queensland state government, has entered into an agreement with Energy Storage Industries Asia Pacific (ESI) to develop a 1 megawatt (MW)/10 megawatt-hour (MWh) pilot plant.

Iron-flow batteries were developed decades ago but have yet to be deployed as a grid-scale energy storage solution. They can operate for up to 25 years, require minimal maintenance and can work over a wide temperature range. This is a type of redox-flow battery and typically consists of two tanks for a negative and positive electrode and pumps. One of the lessons of the energy transition is that there is room for numerous different solutions and to meet the need for extended storage, it's possible that iron-flow batteries may be the answer. These have the advantage of being rapid response and also able to help with frequency control on the grid.īut they also have disadvantages, including they are costly, they don't last long and if there is a fire, they are difficult to extinguish.
