Watt Advisor is here to guide you through the energy transition. The way we produce and consume energy is changing, and this presents new choices for consumers. Should I install rooftop solar? Do I have the best energy plan? Is my home energy efficient? Watt Advisor connects to your usage data and helps answer all these questions. Worried if the grid will have enough capacity during the next heat wave or winter storm? We monitor current and future grid conditions (supply and demand) and send you push alerts as soon as we see any issues with grid reliability. Enter your current energy contract information and we estimate your bill, inform you if you are paying too much for your energy, and send push alerts to remind you when its time to renew your contract. Our solar calculator will tell you the optimal solar system size based on your usage (and if solar even makes sense for you) so you can maximize the economic value of going green through rooftop solar. Watt Advisor algorithms analyze your usage, and additional information about your home to calculate how efficient your home energy usage is and if you should consider a home energy audit. Our app can also integrate with your smart devices (Thermostats, Electric Vehicles - coming soon) and we optimize their usage based on how much renewable energy is on the grid and reduce usage when grid reliability is threatened. We also provides advice on the best time to run your high power devices such as washers and dryers. Our service is provided for free and we currently serve all customers in competitive areas of ERCOT in Texas (ONCOR, AEP, TNMP, CENTERPOINT) whoever your retail electric provider is. We have a vision of a renewable and reliable power grid and can't wait to help you make decisions that will support that goal. Energy can be cheaper greener and more reliable with Watt Advisor!
