I often look at the price of electricity instead of the weather forecast. Low price often means lots of sun. But it can also mean lots wind (and rain), oops.
Prices in the chart below include a €0.13 / kWh tax and about €0.02 / kWh margin for the power company. Otherwise it would be zero or negative. 
13 cents / kWh tax? Seriously wtf
Is that a realtime retail consumer price?
Yeah it's crazy. It's gradually going down over the next few years. The most perverse part of this tax is that it's regressive: industrial users pay almost nothing.
A number of energy companies offer "dynamic" contracts. They announce the price for each hour the day before, which is based on some European auction system. Most people however still prefer a fixed price contract. Right now those go for €0.23 - €0.34 per kWh including tax, depending on how long you want the price fixed (e.g. one month, one year, three years).
Those contracts used to be the norm so the government tax wasn't as obviously weird. Now suddenly you have to PAY taxes to consume negatively priced electricity.
The fun part is that you can program an S9 to act as a space heater at the cheapest hours. Especially if your home is well insulated and it doesn't matter at what time of day you do the heating.
Yep i use the braiins api and the tibber api for that with some code running on a raspi👍
I use Home Assistant and this: https://github.com/Schnitzel/hass-miner
"unfortunately" this winter has been so mild and my house is so well insulated that I only got to run it three times in January. Since then I've had to use *any* heating.
Wow. Where I live, powered by dirty coal, it’s $0.075 / kWh at home and $0.057 / kWh industrial rate where I mine #Bitcoin.

These are today's prices without tax, indeed negative again late morning and afternoon 😁 
NIce chart. How do you get also the price after taxes?
