We’re facing a winter like no other.

Likely confined to our homes, many of us will be concerned about rising bills from extra heating and electricity usage. But it’s not all doom and gloom. We’ve put together some practical tips for how to save on your energy bills over winter and investigated the impact of on site renewables in the colder months.

We’re entering a period of dramatic change for the energy sector. From smaller independents breaking the hold of the Big 6 and consumers generating their own solar power to dynamic pricing plans and smart homes.

The latest innovation is one that combines all of these: Octopus’s Tesla Energy Plan. Previously this was only available to Tesla vehicle owners, but now it’s open to everyone with solar PV and Powerwall battery storage.

The rollout of smart meters is an important part of the energy revolution and transition to a clean electricity network. But if you’re generating your own electricity, how do smart meters and solar panels interact? Can you have smart meters with solar PV? You can - and it may make your life even easier.

Read on for more information on smart metering and Feed-in Tariffs, export tariffs and home batteries.

We’re often asked by our customers which is the best electricity tariff, especially when they’re investing in their own renewable energy systems. There are lots of energy suppliers, with prices varying by location and various contract commitments. But there are particular types of tariffs that we’d recommend looking at, depending on your circumstances:

Recently the Solar Trade Association (STA) published a report modelling the impact of solar PV, battery storage and smart home controls on the UK’s electricity supply and demand. In particular it examines how these technologies can help balance the grid as it becomes ever more complex and under pressure.

We’re going to dig into how solar PV can integrate with smart homes to reduce or even eliminate peak demand.

In light of the recent news, the idea of being grid independent with your own power cut protection has become a lot more attractive. 

We have had a number of customers interested in upgrading their solar PV or battery systems to protect them from power cuts. As we mentioned in a previous blog, a solar PV system alone will not protect you from an outage. With no batteries, if the power goes out, your PV system will switch off. This is a safety mechanism so that you do not discharge any excess PV energy to the grid and seriously injure someone if they are working to repair the grid near your house!

Even if you have a battery, some of them will not be able to island your property from the grid, which is the crucial step needed to have a backup system. Batteries need to follow strict DNO regulations to operate during a power outage as well, and will always need prior grid permission before installing.

Many of our customers are keen to use as much of the solar energy that their home generates as possible in the home. Not only will this reduce bills, it will also increase energy independence.

What is DNO permission and when do you need it?

The DNO or distribution network operator is the company responsible for distributing electricity from the National Grid to your home or business. In the UK there are 14 different district networks or DNO regions which are owned by six groups. For our installation zone, the distribution network operators which we are concerned by are Scottish & Southern Electricity (SSE), UK Power Networks (UKPN), and Western Power Distribution (WPD).

At the end of January, thousands of homes local to us across Reading, Bracknell and Basingstoke suffered power outages for an average of 3 hours. This past week, Storm Ciara denied over 500,000 of us access to electricity. And last August the country was hit by the worst blackout in a decade, affecting hospitals, trains and over a million people. 

Yesterday I had my own modest version of a Victor Kiam moment.

If you are too young to remember Mr Kiam, spend 30 seconds watching this… Mr Kiam's famous line ‘I loved the shaver so much I bought the company’ was the cornerstone of a hugely successful 1979 advertising campaign.

Mr Kiam was swept away by the joy of a sharp shave. For me it was Tesla and the sheer passion with which they are pursuing their mission ‘to accelerate the world’s transition to sustainable energy’.
