Why have energy prices gone up so much?

The energy price Cap is the maximum unit and daily standing charge but is often quoted as an annual figure in the press. The cap was introduced in April 2017 for about four million households with prepayment meters. In 2019 the government extended it to cover the 11 million households that were then on standard tariffs, which historically tended to be the most expensive in the market. The price cap limits the rates a supplier can charge for their default tariffs. These include the standing charge and price for each kWh. The cap is a limit on how much you can be charged for the energy you use, rather than a strict maximum you can be charged overall, so customers with higher energy bills and larger homes will pay more.

What is the new Cap from April 2022?

The energy regulator, Ofgem, has increased the price cap by more than 50 per cent, meaning the average household could be charged about £2,000 a year, up from £1,277. A typical customer paying by direct debit will now pay 28p per kWh for electricity and 7p per kWh for gas. The cap also only applies to variable rates, rather than fixed tariffs, which can be even higher. There are estimated to be about 22 million households on variable rates, and the figure has increased in recent months as smaller suppliers have gone bust, forcing their customers on to variable tariffs with other providers. OFGEM have to balance (1) the price cap reflects the “real world” prices that energy companies are/will be paying on the wholesale markets with (2) keeping prices as low as possible to maintain inflation and reduce fuel poverty.

What’s gone wrong?

The cap is set using historical wholesale prices on the basis that most energy companies will forward buy gas and electricity many months in advance. By contrast, fixed deals typically more closely reflect wholesale prices at the point at which the customer signs up. Whilst the big five energy suppliers have the financial resources to forward buy energy to maintain future prices, most of the new companies did or could not as they never expected wholesale prices to increase so suddenly. When their cost prices escalated, these companies could not pass on the increases to their customers due to the cap. So in effect they were having to sell below cost and many went bust. (26 energy companies have failed since August 2021).

Will energy prices will continue rising?

It’s expected that global wholesale prices will continue to increase in the short term and not likely to come down in the near future. According to research by Evergen Systems, “reducing fossil fuel consumption to meet decarbonisation targets will lead to increases in overall electricity consumption. Whether at an individual household or societal level the demand for electricity will increase underpinning a continued upward trajectory of electricity prices for next 20 years”.

Almost half of the UK’s current nuclear capacity is due to be decommissioned by 2025 and only one new plant, Hinkley Point C, is currently under construction. If no other new nuclear power stations are built, the UK’s nuclear capacity in 2050 will be a third of what it is today. Britain has announced ambitious targets to reduce carbon emissions. No more new petrol/diesel cars and all heating, cooking and hot water from 2030 is expected to increase electricity demand by 250%.

How do I charge my car from the sun?

With the success of electric vehicles over the past 20 years, more and more people are exploring further ways to enhance their environmental experience and reduce their carbon footprint, whilst also enjoying the additional benefit of saving money.

The solar energy market is now firmly on board, saving EV owners up to £1000 per year by charging their car from their solar panels. This is a growing market; all new cars are required to be electric by 2030. By using renewable energy, in this case, solar power, you are helping to save the planet whilst saving the pounds.

Do I need a storage battery to charge my car?

If you are interested in charging your electric vehicle during non daylight hours then you will need a storage battery installed within your system.

Will my car charge be slower compared to using energy from the grid?

Your electric vehicle will charge at the rate your charger allows. The energy generated from your solar panels will have no impact on how fast your charge.

How much am I set to save installing a solar system?

Here at Evergen we have seen our customers save up to an incredible 70% of their energy bills each month.

How does the storage battery work?

Our battery works by storing energy generated from your solar panels when the energy is not in use elsewhere in your home. This means you can use the energy stored during non daylight hours meaning you are saving more money as you are not taking it from the national grid.

Will I still be paying for energy from the national grid?

Yes even with solar panel and storage battery system installed you will still potentially have to use energy from the grid, however this depends on your energy outgoings per month.

Why do I need to reduce my carbon footprint?

Reducing your carbon footprint is very important in todays world. By cutting your carbon footprint it will help to slow down climate change, improve the public health, as well as boosting the worlds economy. By reducing our carbon footprint now we are set to be helping generations to come.

How can I reduce my carbon footprint?

There are many ways we can help the world by reducing our carbon footprint, one being installing solar panel and battery systems to your home. This helps to cut the use of fossil fuels that power all of our homes each and every day.

How many solar panels will I need?

Homeowners typically need an average of 8 panels. However, each case is individual so we offer a free home survey to review how much energy your hot tub requires – as well as the rest of your home – so we can specify a solar system to achieve the biggest savings for you.

Is it better to add more solar panels or a storage battery?

If you already have solar panels installed on your roof and are looking into further ways to reduce your energy bills then there are a couple of options for you.

If you have space on your roof then we could look into adding more to increase energy going into your household. A second option to expand your solar system would be a storage battery. This will allow you to continue to use solar energy throughout non daylight hours. The storage battery can be added to your solar system which will collect solar energy during the day for you to use during non daylight hours. Any excess energy you do not use that is stored in your battery will be sold to the national grid at peak times, so not only are you saving money but also earning it.
