What will you build?

Real-time electricity prices unlock a new generation of energy-smart applications.

🔌

EV Charging

Find the cheapest hours to charge. Users save 30-60% on electricity by shifting to off-peak windows.

🏠

Smart Home

🌡️

Heat Pumps

Pre-heat when electricity is cheap. COP × price = actual cost per kWh of heat — optimize automatically.

Battery Storage

Buy low, sell high. Price arbitrage with Tesla Powerwall, BYD, Sonnen, or vehicle-to-grid (V2G).

Build price comparison sites, monitoring tools, or embed live price widgets on your platform.
