Centrica To Build Largest Battery Storage Project To Date
The title of this post, is the same as that of this news item from Centrica.
These three paragraphs outline the news.
Centrica Business Solutions has secured the development rights to a 65MW two-hour battery storage plant in Perthshire, Scotland, its largest battery storage acquisition to date.
The site in Abernethy is located near a connection for North Sea offshore wind farms and will help manage grid capacity by charging when demand for power is low, and discharging when demand is at its highest.
Once connected to the grid in 2028, the 65MW two-hour battery will be able to store enough electricity to power 130,000 homes for an hour – the equivalent to a town the size of Aberdeen. The discharge could happen up to four times a day.
This map shows the site of the substation at Abernethy.
It seems a site with enough space for a 65 MW/130 MWh battery.
But is that a railway running past the site in the South-East corner of the map?
Yes! It is the single-track unelectrified railway that is used by trains to go between Edinburgh and Perth.
- There are stations at both ends of the single-track section at Ladybank and Perth.
- Abernethy substation looks like it is about halfway between the two end stations.
This page on Scotland’s Railway is entitled Fife Electrification and lists these four phases.
- Haymarket and Dalmeny
- Kinghorn and Thornton North
- Thornton and Lochgelly
- Thorton and Ladybank
The page also says that the electrification will support BEMUs (Battery Electric Multiple Units)
I feel that the electrification to Ladybank and Centrica’s battery could be linked.
- If the electrification was extended a few miles to Abernethy substation, this would surely be a reliable way to power the electrification.
- It would also be ideally placed, if Perth and Ladybank were to be electrified.
- The new battery would surely smooth out any deviations in the power supply.
I certainly don’t expect that Centrica will object to a new customer.
Electrification Between Edinburgh And Ladybank
Consider.
- Edinburgh and Ladybank is 39 miles and takes a couple of minutes over an hour.
- Once, the four phases of the electrification are complete, only the 13.6 miles between Dalmeny and Kinghorn, will be without electrification.
- I doubt that Dalmeny and Kinghorn will ever be electrified, as it includes the Forth Rail Bridge.
- Dalmeny and Kinghorn is 13.6 miles and takes around twenty-four minutes.
It looks like the BEMUs will be under wires for 25.4 miles and nearly forty minutes, which will be more than enough to charge the trains.
Edinburgh And Aberdeen
In Thoughts On Batteries On A Hitachi Intercity Tri-Mode Battery Train, I said this about services between Edinburgh and Aberdeen.
Consider.
-
- The gap in the electrification is 130 miles between Edinburgh Haymarket and Aberdeen.
- There could be an intermediate charging station at Dundee.
- Charging would be needed at Aberdeen.
I think Hitachi could design a train for this route.
The 25.4 miles of new Fife electrification between Haymarket and Ladybank will reduce gap in the electrification to 105 miles and ensure trains leaving Ladybank for Aberdeen had a full battery.
North From Thornton Junction
This Google Map shows how all the railways connect at Thornton junction.
Note.
- The village of Cameron Bridge is in the North-East corner of the map.
- The A 915 running diagonally across the map and to the East of the village of Cameron Bridge.
- In The New Cameron Bridge Station On The Levenmouth Rail Link, I showed how Cameron Bridge station was positioned to the East of the A915 and the village.
- The Levenmouth Rail Link would appear to pass to the South of the village, according to a Network Rail map in the related post.
Thornton junction is a large triangular junction in the South-West corner of the map.
- Thornton North junction is close to Thornton Golf Club, which is shown by the green marker.
- Glenrothes with Thornton station is at the Eastern point of Thornton junction.
- Trains going West from Glenrothes with Thornton station go through Dunfermline and over the Forth bridge to Edinburgh.
- Thornton South junction is South of Thornton Golf Club and leads South through Kirkcaldy station and over the Forth bridge to Edinburgh.
This second Google Map shows the main Edinburgh and Dundee rail line between Thornton Golf Club (Thornton North junction) and Markinch station, which is the next station to the North.
Note.
- The village of Cameron Bridge in the East of the map.
- Markinch station is in the North-West corner of the map.
- Thornton Golf Club (Thornton North junction) is in the South-West corner of the map.
Looking at various maps, Thornton Junction appears very complicated.
- The North-South leg of the junction is at least double-track.
- The North-East leg of the junction appears to be single-track.
- The South-East leg of the junction appears to be single-track.
- The former Levenmouth Rail Link appeared to join the main line at a single-track junction to the North of Thornton North junction
- There is lots of space.
.I’m sure Network Rail can come up with an efficient track layout, that will enable the following.
- Trains can go between Glenrothes with Thornton and Kirkcaldy stations in both directions, as they do now.
- Trains can go between Glenrothes with Thornton and Levenmouth Rail Link in both directions.
- Trains can go between Kirkcaldy station and Levenmouth Rail Link in both directions.
This would enable the service provision, that was specified in Service Provision On The Levenmouth Rail Link.
What Will Be Electrified At Thornton Junction?
This page on the Network Rail web site, says this about the trains that will run the service on the Levenmouth Rail Link.
And while the line will be electrified with overhead wires, services will be operated initially by battery electric units in order to reduce the number of diesels operating on the network as early as possible.
I wouldn’t be surprised to see full electrification between Glenrothes with Thornton and Leven stations, to make sure that the battery-electric trains had full batteries for the run South to Edinburgh.
- The other two legs of Thornton junction would also be fully electrified to give all passing trains a good charge.
- The distance between Kirkcaldy and Markinch stations is 7.3 miles and trains take about ten minutes. I suspect most of this section of the Edinburgh and Dundee line will be electrified. There looks to be about six overbridges that might need raising, but I suspect it would be nothing too terrible, with about the same degree of engineering difficulty as electrifying the Gospel Oak to Barking Line in London.
- I feel with good engineering and guile, enough electrification can be added to the route through Kirkcaldy to get the trains to the South.
- West of Glenrothes with Thornton station, the track looks to be good territory for electrification and enough wires can be added, so that by Cardenden station, there is enough power in the batteries to get the trains to the South.
I have a feeling that by intelligently using the two routes via Kirkcaldy and Dunfermline, Network Rail can increase the frequency of trains over the Forth Bridge.
- This probably partly explains, why trains to Leven go alternatively via Kirkcaldy and Dunfermline.
- 100 mph battery-electric trains help too with their sparkling acceleration.
- Who’d have thought, that at the age of one hundred and thirty, the Forth Bridge will be at the heart of an electrified local train network?
And the only new electrification is based on Thornton junction, over twenty miles to the North.
Electrification Between The Forth Bridge And Edinburgh
Without doubt, the electrification to the South of the Firth of Forth must reach as far North as possible.
Dalmeny station is the most Northerly station South of the bridge and I feel that this could be a practical place for the electrification to end.
Distances from Dalmeny to stations further North include.
- Leuchars – 41.4 miles
- Leven – via Dunfermline – 28.2 miles
- Leven – via Kirkcaldy – 27.3 miles
- Dundee – 48.8 miles
- Perth – 47.4 miles
All these destinations would be within range of Hitachi Regional Battery Trains, which are described in this Hitachi infographic.
Note that the range on battery power alone is 90 km or 56 miles.
Given that the battery-electric trains would be able to grab a battery charge as they passed through Thornton junction, I am fairly certain that Hitachi Regional Battery Trains could reach Leuchars, Dundee or Perth.
An Electric Service Between Edinburgh And Dundee
Dundee is a new station and I doubt, that it was rebuilt without provision for full electrification.
It has two through platforms for Aberdeen and Edinburgh services.
There are also two South-facing bay platforms for regional services from the South.
This picture shows the two bay platforms with an Edinburgh-bound train to the left.
Note.
- In the picture the two Class 170 diesel trains will be going to Edinburgh or Glasgow.
- Scotrail’s plans include an hourly train to both of Edinburgh and Glasgow.
If these two bay platforms were electrified with 25 KVAC overhead wires, these battery-electric services will be possible.
- Edinburgh and Dundee via Haymarket, Kirkcaldy, Thornton junction and intermediate stations.
- Glasgow Queen Street and Dundee via Stirling, Dunblane, Perth, Gleneagles and intermediate stations.
I suspect other routes battery-electric will be possible.
An Electric Service Between Dundee And Aberdeen
The distance between Dundee and Aberdeen stations is 72 miles.
In Solving The Electrification Conundrum, I described techniques being developed by Hitachi Rail and Hitachi ABB Power Grids to electrify routes like Dundee and Aberdeen.
With Hitachi looking to give battery-electric trains a range of over forty miles, it could be just two hops between Dundee and Aberdeen.
I suspect Montrose could be the charging point, as it is forty miles South of Aberdeen.
Conclusion
It appears that the proposed electrification of Levenmouth Rail Link creates an electrification island at Thornton junction, that enables battery-electric trains to reach Dundee.
Coupled with plans to electrify between Stirling and Perth, this means that both Perth and Dundee will be connected to Scotland’s electrified rail network.
I suspect it is also possible to easily extend battery-electric trains all the way to Aberdeen, with only short sections of carefully positioned overhead wires.
