Too lengthy, didn’t learn…
- UK renewables are at a document excessive, this yr alone electrical energy costs dropped beneath £0 throughout 135 hours as a result of extra renewable vitality being generated.
- Throughout these occasions, wind farms are sometimes paid to close down to forestall grid overload. At Octopus, we predict a much better resolution is to permit clients to make use of it as an alternative.
- Even when the wholesale value goes detrimental – a pattern which is rising and signifies an vitality surplus – the retail value of electrical energy by no means is due to Remaining Consumption Levies.
- Eradicating Remaining Consumption Levies from all versatile consumption is important for decreasing renewable vitality wastage and decreasing buyer payments.
Absorbing renewables when it’s considerable: demand flip up
As we embrace electrical options to gasoline boilers and gasoline automobiles, the electrical energy demand is rising and turning into ‘peakier’. Flexibility is all about shifting and spreading vitality peaks to match occasions the place renewables are producing electrical energy. The potential annual financial savings from client flex may attain over £4.6bn by 2030, saving 14% from everybody’s electrical energy invoice. On this yr alone, there have been 135 hours the place renewable era was in surplus, and that is anticipated to rise to 50% of the time by 2035. Throughout these occasions, wind farms are sometimes paid to close down to forestall grid overload.
Quite than letting these precious inexperienced electrons go to waste, we consider in tapping into family flexibility to benefit from them.
Now we have experimented with making electrical energy free to shoppers throughout occasions of surplus. Firstly, two schemes in collaboration with UK Energy Networks and Nationwide Grid’s NESO focusing on particular community hotspots of renewable curtailment. Prospects proved extremely attentive to our Energy-ups periods, see graph, and contributors have saved £100/yr on common.
Then this summer time we began providing 1 hour Free Electrical energy Periods nationally in response to drops within the wholesale electrical energy value. In simply eight weeks, 830k+ clients signed as much as this product and as a collective, clients turned up by over 2.8GWh throughout 7 periods.
Trying on the graph above, it’s clear that there’s an unlimited quantity of flexibility to the households’ consumption. It additionally seems that clients discover new methods to make use of that free electrical energy somewhat than purely shift their utilization from different occasions. This doesn’t imply vitality is wasted; utilizing free vitality to do one thing further, like baking a cake or heating your own home extra, nonetheless boosts the patron’s welfare and well-being. We additionally noticed some vitality shifting between days (charging EVs, washing or batch cooking). With electrical energy costs rising once more, it’s completely important shoppers can profit from low cost electrical energy when it’s considerable, however current coverage doesn’t help this.
Even at occasions when it’s so windy and sunny that wholesale costs flip detrimental, letting our clients profit from this comes as a price to us as a provider.
Introducing: Remaining Consumption Levies
The retail value of electrical energy (i.e. the worth we face as a provider) is extra than simply the wholesale value, it’s additionally community expenses and Remaining Consumption Levies (FCLs). These get well prices from help schemes, similar to subsidy for renewables and apply to electrical energy imports solely. Collectively, these expenses value round 6p/kWh off peak and are even greater at peak time. FCLs account for a few third of the retail value of electrical energy, and these prices are anticipated to rise within the coming years.
Recovering these prices through the electrical energy invoice is problematic, as a result of it 1) makes electrification costlier; and a pair of) distorts incentives for client flexibility.
Why FCLs are a blocker for client flexibility
FCLs primarily enhance the price of electrical energy as a result of they’re charged on a volumetric foundation (i.e. p/kWh). This implies they distort the true value of electrical energy and stop actions which are within the system’s finest curiosity – and stop clients from having the ability to profit from cheaper vitality.
FCLs even have a particularly detrimental influence for dwelling batteries and vehicle-to-grid; as FCLs are charged on import solely, the patron has to pay FCLs for electrical energy going into the battery, however doesn’t get this refunded when that very same electrical energy is exported to the grid later, whereas one other client offtaking the electrical energy from the battery once more has to pay for FCLs. Now we have coated this in additional element right here.
Prospects are prepared, however market indicators are falling quick
Octopus advocates for the elimination of FCLs distorting influence on versatile consumption. We’ve seen from Energy-Ups and Free Electrical energy Periods that clients are prepared to answer market indicators. With out FCLs, all suppliers can be incentivised to move on detrimental wholesale costs and we’d see extra revolutionary buyer choices, particularly, if coupled with the introduction of locational wholesale costs. The instruments we have to stimulate buyer flexibility exist already, the main target now needs to be on sharpening market indicators and eradicating the obstacles so shoppers can reply effectively to them.
