    Apparently, for California, renewable energy use can reach 90% during summer days, though more typically it's less. Today it peaked at 80% at around 11 am. California imports electricity at night.

    This is cool! Thanks for sharing. I live in the SPP's region and I sometimes go to their website to see electricity stats, but it's either presented poorly or I'm just not smart enough to read...

    This is cool! Thanks for sharing. I live in the SPP's region and I sometimes go to their website to see electricity stats, but it's either presented poorly or I'm just not smart enough to read their graphs and visuals. Probably the latter since I'm not employed in the power industry and I'm just a curious passer-by.

    I tried understanding the LMP thing, but that just went over my head.

    Today they launched a US map of wholesale electricity prices. Here's how they describe what they mean: Blue dots are negative prices. If you create an account, you can look at historical data.

    Today they launched a US map of wholesale electricity prices. Here's how they describe what they mean:

    Locational Marginal Price (LMP): This value, typically denoted in $/MWh, is the sum of the other components. It is a price, but also a signal. It tells generators to turn up or down to meet the ever-evolving requirements of demand and managing the grid. LMPs are at the core of nodal markets - these locational price signals can, over time, indicate the most and least valuable locations for new investment. The vertically-integrated utilities of the southeast do not use LMPs and do not provide public locational pricing information. The presence of nodal LMPs is one of the core distinguishing elements of US power markets when compared to their European equivalents.

    LMPs in US markets are generated for both the Day-Ahead as well as in Real-Time. Some non-ISO/RTO regions do have real-time pricing via a balancing market, but have yet to implement day-ahead pricing. Today, Day-Ahead prices are in hourly increments, while Real-Time prices are 5 minutes at their most granular, although markets may produce indicative real-time pricing at different frequencies and settlement may occur at the 5 minute, 15 minute, or even hourly level.

    Blue dots are negative prices. If you create an account, you can look at historical data.
