The Gist Batteries make the lion’s share of their revenue from Ancillary Services, but the portion of revenue from energy is growing noticeably. Using our revenue tracking software we estimated the energy and AS revenue of the ERCOT battery fleet from 7/7/21 to 10/7/23. The results are summarized in the graph below: The Accuracy In…
July 13th was the tightest day in 2022. And batteries are fast become a real game changer in ERCOT; so how did they operate when the rubber hit the road? Well, let’s see, shall we. Filled sections of the chart are the energy offered to the real time market color coded by price range. The…
Wind, Solar, and Batteries are growing in ERCOT, but how fast? The figure below shows the growth in ERCOT’s newest technologies from January 2019 to May 2023 and the capacity additions are staggering.
Good strategy needs good data. At CIMView we collect and store publicly available ERCOT price data and store it in the cloud, ready to query at a moments notice. As experts in the ERCOT marketplace, we also know how to turn that data into actionable reports and visualizations. In this example, we leveraged our CIM…
Check out a demonstration copy of our ERCOT sixty day report viewer. It’s indistinguishable from the full version, except it has a limited date range (3/22/23-4/22/23). It not only has the information from the sixty day reports, but it also has both sides of the battery (charging and discharging) visible at the same time, LMP,…
Good data is a requirement for good business. That’s why CIMView collects and stores vital electricity market information published by ERCOT. The data we collect powers insights that matter. One of the strategies that CIMView employs to ensure data quality is data provenance. Data provenance requires that each record we import into our production datasets…
Wind and solar aren’t the only resources that can be curtailed. For each interval in the 60 day disclosure report CIM View looks at the offer curves and limits for each resource and compares the MWs that would be dispatched at the average ERCOT price (System Lambda) to the MWs that would be dispatched at…
What would ERCOT renewable production look like if it were scaled such that the annual production were equal to the ERCOT load ?” Well, that’s an interesting question, and, frankly, not that hard to answer. Below are the interactive answers for 2019 (scale factor 4.74), 2020 (scale factor 3.98), and 2021 (scale factor 3.53). …
Using our data pipeline and CIM Insight tool, we present the following visualizations of ERCOT outages in plotly. The plots display outages as aggregate power reductions at points in time for a trailing 30-day period in stacked line charts. The charts have many interactive features, including zooming in on selected ranges, removing or highlighting data…
Here’s a visualization of the last few years of power generation in ERCOT by resource type. The plots display the daily production of power in ERCOT both in total MWh/day and in percent of total production by day. The charts have many interactive features, including zooming in on selected ranges, removing or highlighting data by…
