See when Dutch electricity is cheap — and when it's expensive. Jeroen.nl shows live power prices per kWh, straight from the EPEX exchange, updated every hour and every quarter-hour. Important: this app is designed for the Dutch electricity market only. It calculates consumer prices based on Dutch energy taxes, VAT and supplier markups. Not useful for other countries. —— WHAT YOU CAN DO —— • Live electricity price per kWh, every hour and every quarter-hour • EPEX spot market price (raw) and full consumer price (incl. Dutch energy tax, VAT and your supplier's mark-up) • Chart of today's and tomorrow's prices as soon as they're published • Sell-back rate for solar panels visible • Compare Dutch dynamic-tariff suppliers —— SMART ALERTS —— Set push notifications on your own thresholds: • "Alert me when the price drops below 15 ct/kWh" • "Send me the cheapest 3-hour block every morning at 7:00" • "Notify me when tomorrow's day-ahead prices are published" • "Warn me when the most expensive hour is coming up" —— FOR WHOM —— • Anyone with a dynamic energy contract with a Dutch supplier such as Tibber, Zonneplan, ANWB Energie, NextEnergy, Frank Energie, Powerpeers and many others. • Solar panel owners who want to know when feed-in pays best • Home battery owners looking for the smartest charge/discharge moments • EV drivers who want to charge at the cheapest time • Anyone curious about the Dutch power market and EPEX-spot dynamics —— WHY JEROEN.NL —— Independent. No supplier interests, no ads. Prices are pulled daily from the EPEX spot market and calculated straight into the consumer price for your Dutch supplier — including tax, VAT and mark-up. So you don't just see the raw exchange price, you see what you actually pay. Jeroen builds this app himself and reads every piece of feedback personally. —— MORE ON THE WEBSITE —— Full analyses, comparisons and background at jeroen.nl. Questions or feedback? hoi@jeroen.nl.
