Some retailers pass through wholesale prices. Kilo Wasps shows when the grid pays you or spikes to 300c/kWh+.
Your retailer pays 3c/kWh and charges you 35c. The loophole: you can buy at 3c too. The fine print: sometimes it's $3.
Solar feed-in hit $5/kWh during the last big spike. Your panels made bank for an hour. You'll be talking about it for a month.
Real users, real spikes, real bragging rights. We don't talk about the Tuesday your bill hit $40 before breakfast.
