WattSpy gives you access to the European EPEX Spot Market, where electricity prices for each hour or quarter-hour of the day are established. If you have an energy contract with dynamic pricing, you can optimize your electricity usage by adjusting your electricity consumption patterns based on the price fluctuations. Here's how: - Shift High Consumption Activities: reduce energy costs by scheduling energy-intensive activities (like EVs', washing machines, dishwashers, or electric heating) during hours when electricity prices are lower. - Use Home Automation: home automation systems or smart appliances can automatically adjust the timing of electricity usage based on the predicted lower-cost periods provided by the Epex-client. - Energy Storage: energy storage systems (like batteries) can store electricity during low-price hours and use it during peak-price hours.
