Datacentre sector hits back at claims that West London electricty grid capacity crunch is its fault

The notoriously secretive datacentre industry has found itself villainised by the national press to be an insatiable, power-hungry entity that’s sucking the West London electricity grid dry and exacerbating the capitals housing crisis.

That is on the trunk of a briefing note, distributed to property developers and trade associations on 22 July by the higher London Authoritys (GLA) Development Service, entitled West London electrical capacity constraints, having said that an instant influx of server farms across the M4 corridor has left the electricity transmission and distribution networks in the London boroughs of Ealing, Hillingdon and Hounslow suffering capacity issues.

Datacentres use large levels of electricity, the same as towns or small cities, to power servers and ensure resilience operating, said the note, seen by Computer Weekly. The scale of electricity demanded by these datacentres [has absorbed] the rest of the electricity capacity in SSENs [Scottish and Southern Electricity Networks] West London region for the rest of the decade.

Consequently, the developers of major housing, commercial and industrial developments have told the GLA they face a wait of many years to possess their builds installed to the grid, with some applicants being told it might take until 2035 to obtain a grid connection.

The Financial Times ran a tale concerning the notes contents, with the headline West London faces new homes ban as electricity grid hits capacity.

However, it seems the contents of the GLAs briefing note might have been sensationalised somewhat, with energy market sources telling Computer Weekly that there surely is no immediate shortage of power capacity in West London.

Instead, the constraints discussed will be the volumes contracted in some instances for post-2030, they said. There is absolutely no ban on new-building housing developments because of electricity connections.

Eddie Lavery, Hillingdon Councils cabinet member for residents services, described the Financial Times reporting of the problem as a somewhat scaremongering story that had blown the truth of the problem out of proportion.

He said: We have been unaware of any housing schemes planned for the borough being affected. Addititionally there is evidence that power capacity has been reserved for developments that could never happen which latent capacity ought to be distributed around schemes that’ll be delivered.

We understand the GLA is spending so much time to resolve the problem as fast as possible. In the meanwhile, we’ve every confidence well be delivering on our housing promises.

Matthew Evans, director of markets at TechUK, told Computer Weekly that the tech trade association had received a clarifying statement from the GLA that reiterated that there surely is no ban on new housing developments due to the datacentre sectors rapid growth in West London.

In a recently available statement of clarification carrying out a roundtable with the info Centre Council at TechUK, the GLA has stated that the West London electrical capacity constraints document will not imply a ban on future housing in London, as previously reported by way of a few news articles, said Evans.

TechUK and the [datacentre] operators we represent welcome this clarification, which dispels the adversarial framing towards among cross-industry collaboration. We think that obtaining the relevant stakeholders round the table may be the only solution to solve the existing crises.

Several days following the Financial Times article appeared, The Daily Telegraph published articles concerning the GLAs note, where it described datacentres to be energy vampires which are sucking Britains grid dry.

It really is fair to state the datacentre industry have not taken kindly to being characterised in this manner, considering that some operators are pairing their West London datacentre builds with investments in propping up the grid in the encompassing area.

Colt Datacentre Services got the green light from Hillingdon Councils Major Applications Planning Committee in April 2022 to proceed using its plans to create a 400m campus comprising two datacentre buildings in Hayes, West London.

An infrastructure assessment completed within the planning process figured there is insufficient electrical capacity to meet up certain requirements of the brand new datacentre, as detailed in a planning document circulated to committee members and seen by Computer Weekly.

However, Colt has decided to fund the reinforcement of an area electricity substation and cover the expense of new cables and connections at another substation nearer to its proposed datacentre.

These upgrades will need four years to perform and can provide additional convenience of other users and invite expansion in to the 2030s, the report said.

Accordingly, the applicant has had proactive steps to meet up the infrastructure requirements of the development and demonstrates the scheme won’t negatively impact future electricity suppliers within the Hayes area, the document added.

Datacentre industry scapegoat for government under-investment

The prevailing feeling on the list of datacentre industry players Computer Weekly spoke to concerning the GLAs note (and the press coverage of it) is that the sector has been made a scapegoat for a long time of under-investment by successive governments in the UKs energy generation, transmission and distribution networks.

As proof this, Ed Ansett, chair and founder of datacentre engineering consultancy firm i3 Solutions Group, remarked that having less capacity in the united kingdom grid is a way to obtain ongoing concern and discussion for a lot more than 15 years.

The moral panic being created about datacentres preventing housing development in West London comes hot on the heels of weekly in which it had been reported that the united kingdom procured power from Belgium at an archive price of nearly 10,000 a megawatt hour, that is 5,000% greater than typical, to overcome a potential blackout the effect of a coalition of peaking power demand and a bottleneck in the grid, Ansett told Computer Weekly. The shortcomings of UK grid capacity aren’t new.

Further proof this is the work of Ian Fells, an Emeritus professor of energy conversion at the University of Newcastle upon Tyne, who has written and spoken prolifically during the past concerning the shortcomings of the united kingdom grid.

In a 2008 article for The Engineer, Fells spoke of the necessity for considerable investment to be produced in the National Grid and the nations own energy generation capabilities in the light of the UKs growing electricity usage.

For days gone by 15 years at the very least, he’s got been very vocal concerning the insufficient capacity in the united kingdom grid, pre-dating by some time and effort the expansion of the datacentre sector, which includes been a hallmark of modern times, said Ansett.

The Institution of Mechanical Engineers also raised a red flag in 2016 concerning the looming threat of an electricity supply crisis in the united kingdom, because the government had didn’t build sufficient replacement resources of energy generation before its plans to close all coal-fired powers stations by 2025.

And Computer Weekly has unearthed further and much more recent evidence that suggests the federal government continues to be dragging its feet on matters of the UKs energy security.

When Computer Weekly initially contacted the GLA for touch upon this story, it received a statement on 27 July having said that the London mayor, Sadiq Khan, wrote to the Department for Business, Energy and Industrial Strategy (BEIS) weeks hence to request a gathering to go over the electricity capacity issues in West London, however the request was declined.

Several days later, and following the story garnered further national and tech press coverage, the GLA gave Computer Weekly an updated statement that confirmed Khans meeting request with BEIS had now been accepted. Amid a housing crisis, he could be contacting the ministers to utilize him to solve this problem urgently, the statement read.

Cross-industry collaboration to improve grid stability

The GLA document said the West London capacity constraints are particularly acute in Hounslow and Ealing, but elements of Surrey and Berkshire like the datacentre hub town of Slough may also be feeling the power pinch.

The document also featured a call to arms from the GLA fond of property developers, datacentre operators, local councils and regulators to supply it with feedback on how to generate more grid capacity.

Our collective aim would be to help find innovative answers to mitigate the immediate constraints, unblocking developments that could otherwise be delayed or stopped within their entirety, while ensuring economic development isn’t adversely affected, the GLA document said.

i3 Solutions Groups Ansett said a proven way the datacentre industry can lend its support to the GLA is by making the large sums of spare power capacity they hold open to the grid.

A very important factor which today isn’t being considered [enough by operations] may be the level of spare power capacity actually held by datacentres, as well as their power generating and energy storage capabilities, he said.

Taken together, this capacity incurs gigawatts of power enough in order to avoid the necessity to build at the very least two power stations, and certainly a game-changer with regards to the power that might be distributed around support the grid sometimes of peak demand.

This might require datacentre operators to become active participants popular response schemes, which may require some easily made adjustments with their server farm setups therefore the power stored within their backup generators for instance could be distributed around the grid during peak times.

Basically, datacentres could disconnect from the grid and operate on their very own generators or generate straight into the grid, said Ansett. In any event, being an energy-intensive industry, it could seem sensible for the grid to possess a dialogue with the datacentre industry, simultaneously gaining insight to the sectors power requirements and capacity when shortages are forecast.

Rees Westley, head of utilities at datacentre design consultancy Business Critical Solutions (BCS), said his firm has been advising the operators it works together with to accomplish their bit to make sure their operations usually do not put undue and extra strain on the grid for some time.

We have been currently advising clients on several answers to reduce their reliance on the National Grid, including creating more efficiency and/or scaling back on size, he said. In some instances there is the choice to take into account generating their very own capacity to supplement any shortfall, utilising renewable power such as for example wind, hydro, solar and waste to energy.

This could be built by the datacentre owner or funded by among the growing amount of financial institutions which are starting to spend money on power generation because they start to see the demand and resulting opportunities. However, the reliability of the kind of renewable energy isn’t guaranteed since it isnt always sunny or windy, which means this often must be associated with a kind of battery storage.

Another way operators might help is by broadening their horizons when deciding where far better locate their datacentres and perhaps consider opening sites where there’s surplus grid capacity, said Westley.

We’ve a scenario where we’ve a concentration of demand in West London and the National Grid is indeed constrained that it’s struggling to import or export power, he said. However, the Scottish network is under-utilised to this extent that it’s being powered down at times since it isnt used. Addititionally there is significant alternative power generation through on and offshore wind generators.

The problem is that the lines that run from north to south are constrained and so are struggling to move power between them. Construction work to handle that is currently under way but will need around eight years.

Which means that the more power-hungry facilities will have to consider locating in the north of the united states. This is practical once we are seeing more industry doing exactly the same, such as for example Rolls-Royce.

This type of strategy may need some trade-offs to be produced, given that one of many explanations why the M4 corridor is this type of popular location for datacentres is how well connected it really is, which is very important to operators that are looking to provide end-users low-latency connectivity.

The M4 corridor is served by transatlantic cables that run from Cornwall to London, and locating a datacentre further afield might mean needing to compromise on connectivity speed for power and the chance to obtain server farms built quicker.

The GLA has given stakeholders until today (Friday 5 August) to place forward suggestions on how far better address the grids supply constraints, and without doubt the datacentre community will undoubtedly be waiting with bated breath to see what the implications of the consultation exercise may be for this.

For the time being, the power Networks Association, which represents the interests of UK and Irelands energy networks business, said it really is using every tool open to manage the problem.

Electricity networks are employing every tool available, including deploying innovative technologies, to accelerate connections and make sure that future demands are managed as efficiently as you possibly can, a spokesperson told Computer Weekly.

There’s significant collaboration over the industry, the higher London Authority sufficient reason for the housing developers themselves to handle these challenges, but a long-term method of investment is necessary. We have been in dialogue with [regulator] Ofgem to create changes with their reactive regime and make sure that where new infrastructure is necessary, network companies can build it once and build it right.
