Replace, 22 April
Within the two weeks since our first daytime plunge, there’ve been a number of extra days the place AgileOctopus costs have dropped under zero for lengthy durations – for the final three consecutive days, the truth is. That is nice information for our clients who’re paid for the facility they use, but additionally provides us an unprecedented alternative to see the challenges of a greener vitality system.
Common demand in April has to this point fallen 17% under the anticipated degree for this time of 12 months as companies stay closed because of the Coronavirus outbreak. Coupled with sunny and windy climate throughout a lot of the UK, there’s been a far greater share of renewable technology feeding the grid than ever earlier than. With extra wind, photo voltaic and hydro within the technology combine comes extra variability, which requires flexibility to maintain the grid in fixed equilibrium the place provide and demand steadiness completely.
Sometimes, the grid has met this balancing problem by counting on conventional, highly-polluting technology (gasoline, coal and oil) which could be turned down flexibly and on the expense of renewables. By providing to pay clients to make use of extra throughout occasions when there may be an abundance of potential inexperienced technology AgileOctopus pays clients to show up their demand. This implies fewer renewable crops sitting idle and extra of our vitality is coming from carbon impartial sources.
On Sunday Fifth April, 1000’s of consumers on our AgileOctopus tariff bought paid to make use of energy between 10.30 and 4pm. Agile is a great tariff, designed to move on the extremely changeable market value of electrical energy to clients as a option to reward them for utilizing energy when there’s numerous renewable vitality on the UK grid, and fewer demand for it. Typically, costs even go detrimental, and clients are paid for the facility they use.
First, how do Agile value plunges occur?
The wholesale worth of vitality adjustments each half an hour, based mostly on elements like vitality demand (i.e., how a lot energy properties and companies will use in whole at the moment) and what sorts of gasoline can be found.
Vitality demand is especially vital in pricing as a result of the vitality grid at all times must be balanced. For each lightbulb and kettle that will get switched on across the nation, there must be an actual match for that energy being pumped into the networks. When demand is decrease than regular, the grid can find yourself with an excessive amount of energy and danger changing into unbalanced, which might in some circumstances result in blackouts. To keep away from conditions like that, when demand is low, the grid must discourage turbines from producing vitality, and desires to encourage suppliers to take extra vitality – and this occurs by the worth of vitality going up and down. When there may be an excessive amount of energy within the system the grid can generally even pay for suppliers to make use of extra or turbines to supply much less – and that’s when costs can go detrimental.
Whereas most standard vitality tariffs clean out these value fluctuations for customers, AgileOctopus passes them on – so clients can get the advantages of free or low-cost vitality, and are empowered to determine for themselves in the event that they wish to use much less when energy is in excessive demand, or to make use of extra when there’s a surplus.
All previous Agile ‘value plunges’ we’ve had have been within the early hours of the morning, when few individuals are utilizing vitality (so demand is de facto low) and there’s numerous wind blowing. This time, for the primary time ever, we had an almost six hour value plunge all through the day!
So, why was there a daytime value plunge on Sunday?
Take a look on the graph under for visualisation of what occurred…
Forecasted wind and photo voltaic technology vs whole UK vitality demand, April 4th-Fifth 2020
The Coronavirus outbreak has brought about a giant general lower within the UK’s whole vitality demand.
Whereas family vitality use goes up, enterprise vitality use goes approach down. It’s true that many people are at house utilizing extra vitality than we would’ve earlier than, although it’s rather a lot lower than you would possibly assume as we’re beginning to come into hotter climate so excessive heating payments are coming down. Our knowledge scientists have used good meter readings from 60,000+ properties to work out that the common isolating family was utilizing round 4% extra vitality within the very first week of social isolation (learn their full findings right here). However the outbreak has additionally meant numerous massive industrial buildings with far greater vitality demand – from massive workplaces and factories to pubs and purchasing centres – have needed to shut their doorways. This massive drop in enterprise vitality consumption far outweighs the small improve in home vitality consumption. General, the UK’s vitality demand is down someplace between 9-13%.
Then, on Sunday morning, the particularly sunny and windy climate introduced a surge in renewable technology. This, coupled with the UK’s decrease vitality demand, meant that renewables offered a record-breaking share of the UK’s vitality wants on Sunday – 40% from wind and virtually 20% from photo voltaic.
This mix of things meant market vitality costs went detrimental, and so Agile costs plunged:
The 1000’s of consumers on AgileOctopus had been despatched an alert on Saturday night to allow them to know they’d be paid to make use of vitality the following day. Everybody scrambled to prepare to make use of as a lot energy as they might through the plunge to assist dissipate the grid’s greenest electrons – whether or not that is perhaps charging an electrical automotive, charging up different batteries from energy banks to telephones and laptops, placing on a great deal of washing, even baking bread…
Issues I’m doing throughout @octopus_energy Agile plunging value interval..
⚡️Charging the automotive
⚡️Dishwasher on
⚡️Washing on
⚡️Dryer on
⚡️Oven clear perform on
⚡️Sizzling water on for showers we delayed this morning
⚡️Children charging their energy banksAm I lacking something 😂

Right here’s one buyer’s invoice for Sunday – 44 kWhs used, for a complete price of -£0.09.
This weekend’s report excessive numbers of renewables present a vital alternative for this business to expertise what an vitality market of the longer term would possibly appear to be – and actually confirmed the worth of dynamically-priced tariffs like Agile.
Agile’s low costs reward clients for utilizing vitality when it’s greenest, reasonably than at occasions when it’s most handy. If clients dissipate as a lot vitality as they will throughout occasions when the electrons coming down the wires are largely inexperienced ones, there’ll be much less want for them to make use of energy through the each day vitality ‘peaks’, when there’s tons extra vitality consumption and so extra fossil gasoline turbines need to be referred to as upon to satisfy the demand. Taking Sunday for instance – all these clients did the washing, charged their automobiles, cooked, and charged their home equipment in the course of the day utilizing solar and wind energy, which means they wouldn’t need to do it at 7pm that night when everybody else within the nation is utilizing numerous (much more polluting) vitality.
That is a part of an enormous plan to assist decarbonise vitality, experimenting with an vitality system dictated by provide reasonably than demand. This shift is essential as we transfer in direction of being powered extra by ‘intermittent’ vitality sources like solar and wind energy.
In a system dictated by provide, when our vitality sources are considerable (i.e., a windy or sunny day) folks would swap on and use all of the vitality they will – a completely totally different system to our present demand-based one, the place folks use vitality each time they need, and the grid does something it may possibly (together with firing up coal energy stations) to satisfy that demand. This weekend offered the vitality networks a chance to handle this provide and demand with a far greater share of energy coming from intermittent renewable sources.
As an increasing number of wind and photo voltaic farms go stay across the UK, we’ll proceed to see the next share of our vitality coming from intermittent, renewable sources. Meaning we’ll must collectively adapt with options to verify we are able to both retailer the vitality in batteries so it may be used later, or get good house merchandise that automate home equipment to be used on the most cost-effective and greenest occasions into the mainstream. In a approach, Agile clients are prototype “load shifters” for this future vitality system, displaying the way it might work at a a lot bigger scale.
