So we'd need electric utility companies to share the live data of how many kwh of solar and wind people are selling back to the grid in order to get an accurate regional comparison of real-time carbon intensity?
FWIU, they're already parsing the EIA data; but it's significantly more delayed than the max 2 hour delay specified by ElectricityMap.
Here's the parser for the current data from EIA: https://github.com/tmrowco/electricitymap-contrib/blob/maste...
Should the EIA (1) source, aggregate, cache, and make more real-time data available; and (2) create a new data item for behind the meter kwh from e.g. residential wind and solar?
(Edit) "Does EIA publish data on peak or hourly electricity generation, demand, and prices?" https://www.eia.gov/tools/faqs/faq.php?id=100&t=3
> Hourly Electric Grid Monitor is a redesigned and enhanced version of the U.S. Electric System Operating Data tool. It incorporates two new data elements: hourly electricity generation by types of energy/fuel source and hourly sub-regional demand for certain balancing authorities in the Lower 48 states.
> [...]
> EIA does not publish hourly electricity price data, but it does publish wholesale electricity market information including daily volumes, high and low prices, and weighted-average prices on a biweekly basis.
AFAIU, retail intraday rates aren't yet really a thing in the US; but some countries in Europe do have intraday rates (which create incentives for the grid scale energy storage necessary for wide-scale rollout of renewables).
(Edit) "Introduction to the World of Electricity Trading" https://www.investopedia.com/articles/investing/042115/under... :
> Energy prices are influenced by a variety of factors that affect the supply and demand equilibrium. On the demand side, commonly referred to as a load, the main factors are economic activity, weather, and general efficiency of consumption. On the supply side, commonly referred to as generation, fuel prices and availability, construction costs and the fixed costs are the main drivers of the price of energy. There's a number of physical factors between supply and demand that affect the actual clearing price of electricity. Most of these factors are related to the transmission grid, the network of high voltage power lines and substations that ensure the safe and reliable transport of electricity from its generation to its consumption.
Which customers (e.g. data centers, mining firms) would take advantage of retail intraday rates?
How does cost and availability of storage affect the equilibrium price of electricity?
