Last night our energy company paid us for electricity! Today we get paid to drive, shower, cook and power our home.

It was about 4pm on Saturday 15th February 2020 a post of my Facebook feed showed a picture of negative energy pricing for later that night. Essentially people on an energy tariff called Agile from Octopus were going to be PAID to use electricity overnight.

Octopus Agile Tariff 16/2/2020

Our family has been on the Octopus Go tariff since we installed more solar panels and battery storage in spring 2019.

With the Octopus Go tariff you pay 14.9p per kWh for 20 hours a day and then between 00:30 and 04:30 that drops to 5p per kWh. So every night both electric cars are charged, the Tesla Powerwall 2 battery charges and the Mixergy Hot Water tank heats to 100%.

However with Octopus Agile tariff the cost of electricity varies throughout the day in half hour segments. It can be as cheap as 1p per kWh overnight but at peak times this can leap top over 25p per kWh. So to maximise Agile you need to be able to vary when you use electricity, either use smart devices or set appliances to come on when the cost is cheap. Having battery storage allows us to store energy when it is cheap and avoid having to pay when the cost per kWh is high.

Storm Dennis. How can energy prices go negative? I mean, electricity still has to be made and transmitted, nothing in life is for free! Well I have seen this happen 3 times in recent weeks. You can’t turn off wind turbines! There have been some significant storms hitting the UK in recent weeks, and when the wind is blowing at gale force, but it is the middle of the night, well there is too much electricity in the grid. You can’t turn off wind turbines, or indeed Nuclear Power within a few minutes, so far better to incentivise consumers and industry to use the spare energy but paying them to use the spare energy.

So that Saturday night I contacted Octopus via twitter and a couple of emails later I was switched from Octopus Go to Octopus Agile and ready to be paid to use electricity for the first time in my life. Overnight the cars charged, the hot water heated, the underfloor warmed, washing machine spun, dishwasher cleaned. By 6am the house had 63.5 kWh of energy, about what the average UK house used in 6 days. Initial cost analysis below:

Our Agile Octopus 16 February usage vs Standard Tariff

Monday Update: Data from the Octowatch app lists that for the entire 24 hours on Sunday 16th as usage: 94.9 kWh – total cost : £0.86. Amazing !

So today, the 16th February we will actually be in energy credit. The Mini PHEV can drive 20 miles, the Tesla Model S can drive 220 miles, the Mixergy 250L tank will deliver 5 showers, and the Tesla Powerwall 2 will run the house all day, and we were paid to do all that. Mad, mad times. Hopefully all houses will be able to do this within a few years with smart devices switching on when prices drop, helping the National Grid maintain a constant load, and hence more efficient.

Now of course all that infrastructure in the house is not free, the cars, battery storage and hot water cylinder all have a large upfront cost. However, when I wrote the original business case for those investments I had not even factored in negative energy pricing, as that comes more common, the return on this those investments increases. Oh and nice aside, should the lights go out in Storm Dennis, the house can run on battery power for a couple of days.

MyEnergi Hub & App brings full remote control to Zappi & Eddi

Hot on the heels of the new Zappi charger launch, Lincolnshire based smart energy company MyEnergi have announced the launch of their keenly awaited mobile app and hub.

Once installed, users will be able to monitor the energy use within their house as well as control smart power diverting devices like the Zappi and Eddi products. Zappi allows excess power from renewable energy sources, such as Solar PV or a Wind Turbine, to be redirected to charge an Electric Car rather than be exported to the National Grid. Eddi diverts excess power into an immersion heater within a hot water cylinder heating the water for free.

A pre-requisite for the app to work in the brand new Myenergi Hub which retails for £85. This new hub brings together the Zappi and Eddi real time status as well as the ability to monitor energy flows from Renewable Energy sources, the grid and even connected Battery Storage devices such as the Tesla Powerwall 2.

The look and feel is very similar to the Tesla mobile app which has a dependency on having either a Tesla car or Powerwall device whereas the Myenergi app monitors energy flows by simple CT clamps meaning users can choose any brand of Battery Storage or solar panels.

The new hub and app will be available in February 2019. Full details on: https://myenergi.uk

Nissan LEAF Plus pricing Leaked in the USA?

In 2019 I will be replacing my VW Golf GTE that I will have had on a 2 year Company Car lease. Frankly I have had enough of short range plug-in hybrids and it looks like we are now finally seeing the longer range battery packs, but still at a premium.

The Jaguar iPace looks like an amazing car but pricing in the UK starts at £68k. So all eyes are on the next iteration of the Nissan LEAF with an upgrade from the 40kWh battery pack to 60kWh. But when will the new model be release and what premium for this bigger battery pack? Interesting news from the USA overnight with a potential leak of future pricing from Cars Direct

Those waiting for an extended-range Nissan LEAF with a 60-kWh battery pack may be in for a wait. Initial order guides reveal the new variant is slated to begin production in January 2019, about 5 months after the brand started building the 40-kWh model.

Although Nissan hasn’t provided official specs yet, the 60-kWh LEAF is expected to have a range of up to 225 miles. That’s nearly 50% more than the 151-mile range of the current LEAF. Dealers are just now starting to receive 2019 LEAFs with the 40-kWh configuration.

In terms of price, the 40-kWh LEAF ranges from $30,885 for the S to as much as $37,095 for the SL before applicable state and federal incentives. Nissan’s preliminary pricing sheets show the 60-kWh variants commanding about a $5,500 premium over their 40-kWh counterparts.

If that proves to be the case, that could result in a price range starting at just over $36,000 for the 60-kWh LEAF S and extending to around $42,500 for the SL trim. As a result, the LEAF could become a compelling alternative to the Chevy Bolt EV, which ranges from $37,495 to $41,780 and offers up to 238 miles of driving.

Interestingly, we’re seeing evidence that around the same time that Nissan introduces S, SV and SL trims with the 60-kWh configuration, the brand will stop building the 40-kWh SL model. We don’t have an official reason yet from Nissan, but we think we can offer a guess.

At just over $37,000, the 40-kWh SL could equate to a less-attractive option if Nissan is able to offer the 60-kWh model at around $36,000. While the entry-level trims will allow the brand to advertise lower payments, the benefits of upgrading could become a bit clearer for consumers.

One factor that could play a big role in purchase decisions could be the scheduled phase-out of the $7,500 federal EV tax credit once 200,000 vehicles are delivered. Last month, Nissan said U.S. sales of the LEAF reached over 123,000 cars since the model’s introduction.

In contrast, EV automaker Tesla recently told customers to place orders by October 15 to get the full amount. We won’t speculate on how long it’ll take Nissan to get to that point, but it at least appears that early 2019 could be a more exciting time to cross-shop the LEAF with competitors like the Bolt in terms of specs and pricing.
