Electricity price predictions

When the energy cap comes up for renewal I think it will rise to 26.5p per unit, any thoughts of the collective?

@jamespa had the closure of coal powered electricity generation had a part to play in general increase?

Rapid Decline:
Coal's share of the UK's electricity mix fell dramatically, from around 30% in 2014 to a historic low of just 0.5% in 2024.

Major Policy Shift:
The UK government set a target to end all coal-fired power generation by 2025. In 2021, this deadline was brought forward to October 2024.

Driven by Renewables:
The decline in coal was primarily driven by the rapid expansion of renewable energy sources, particularly wind and solar power, which increased significantly since 2008.

Ratcliffe-on-Soar:
The Ratcliffe-on-Soar power station, the last operational coal plant, officially closed on September 30, 2024.

Coal-Free Milestones:
The UK achieved several milestones, including its first 24-hour coal-free period in 2017 and the first full week without coal power in May 2019.

@jamespa or it might be related to the number of nuclear power stations closed over that time frame?

Since 2008, five UK nuclear power stations have closed: Hinkley Point B, Hunterston B, Dungeness B, Hartlepool, and Heysham 1. Three Advanced Gas-cooled Reactor (AGR) stations (Hinkley Point B, Hunterston B, and Dungeness B) have ceased generation and begun defueling as part of their decommissioning process. Additionally, Hartlepool and Heysham 1 also closed in 2019.

No to both so far as I can see, The wholesale price was pretty constant during this period so its doesnt appear to have anything to do with generation costs!

@diverted-energy hi. That sounds a good deal. We use ~8700kWh/year. I currently pay 27p/kWh during the day and 7p between 23:30 & 5:30 daily. I pay Octopus £104/month & have built up a good cash buffer for the winter.
When I follow your link I get £200/month. They don’t seem to quote on the EV tariff until you move 😳. Which is a bit of a gamble. The 24p day rate is lower, but the 8.99p overnight is higher. I need to get my calculator out. How does the free energy work?

Daikin Altherma 3H HT 12kWh ASHP with Mixergy h/w cylinder; 4kW solar PV with Solic 200 electric diverter; Honda e and new Hyundai Ioniq 5 N electric vehicles with Myenergi Zappi mk1 charger
