California and Hawaii have already implemented price curves that make purchasing solar + storage viable for homeowners. As more states adopt these policies and more homeowners adopt batteries the duck curve can be solved. Also battery storage gives the added benefit of not needing a gas generator when the grid goes down if you have an islanding system!
- coryfklein 8y agoHow does one implement a price curve? By supply & demand, it is just the result of energy production + energy usage. Are you saying that California has somehow made energy scarce during the day or are you talking about price manipulation?
- IpV8 8y agoThe price of buying/selling to/from the grid is different at different times of the day. Artificially set by the utility. Different utilities have different rules. In some you can take advantage of the arbitrage if you have a battery; buying during the day and selling in the evenings. Exe here is San Diego's pricing from the perspective of consumption only: https://www.sdge.com/residential/pricing-plans/about-our-pricing-plans/time-use-plans https://www.sdge.com/residential/pricing-plans/about-our-pri...
- ProblemFactory 8y agoYou could skip the price models/curves, and just go with a real-time exchange. Something like NordPool (https://www.nordpoolspot.com/ https://www.nordpoolspot.com/), which trades electricity between UK, Germany, Nordics and Baltics. Electricity price on the market changes every hour depending on production and consumption. You can trade on it like on any futures market, or as an active participant if you had a large battery or transmission cables. Local utilities here offer "market price + 5% margin" plans to home consumers if you want to take advantage of the lows to adjust your usage.
