  • Gas power generation across five-minute intervals?

    Gas power generation across five-minute intervals?

    Power generation data are aggregated for ten of the largest CCGTs and gas peaker plants in Australia, across five-minute intervals, May-2024 and May-2014. This makes for a fascinating case study into how gas turbines are used to stabilize power grids, backstop renewables, and how this has changed over time.

  • California’s grid: wind and solar statistical distributions?

    California’s grid: wind and solar statistical distributions?

    This data-file aggregates the statistical distribution of total electricity demand, solar generation and wind generation, every 5-minutes, across California, for the entirety of 2022, in order to understand their volatility and curtailment rates. The data suggest that wind and solar will most likely peak at 50-55% of renewables-heavy grids.

  • Very long term historical commodity prices and disruptions?

    Very long term historical commodity prices and disruptions?

    This data-file aggregates long-term historical commodity prices back to 1800, predominantly in the US, using academic records and census data. Historical commodity prices generally fell 30-70% in the 19th and early 20th century, punctuated by supply disruptions due to wars, then rose by 12.5x from 1945 to the present day.

  • Renewables: share of global energy and electricity by country?

    Renewables: share of global energy and electricity by country?

    This data-file is an Excel “visualizer” for some of the key headline metrics in global energy: such as total global energy use, electricity generation by source and growing renewables penetration; broken down country-by-country, and showing how these metrics have changed over time.

  • Sentient Energy: smart grid breakthrough?

    Sentient Energy: smart grid breakthrough?

    This data-file is a technology review for Sentient Energy, assessing innovations in smart grids. Its technology can achieve energy savings via a combination of “Conservation Voltage Reduction” and “Volt-VAR optimization at the grid edge”. This also helps to integrate more solar and EV charging into power grids. We explain the technology.

  • Powin: grid-scale battery breakthrough?

    Powin: grid-scale battery breakthrough?

    Powin commercializes energy storage hardware and software. Its LFP battery system is 30% more compact than peers, at 200 MWH/acre, and modular, meaning it may be 50% faster to install. Our patent review finds a moat around specific process improvements, to help back up the short-term volatility of solar and wind.

  • Global gas prices: by country?

    Global gas prices: by country?

    Global gas prices by country are often measured at the world-famous delivery points for liquids futures contracts, such as Henry Hub and the Netherlands’ TTF. This data-file takes a broader approach, aggregating the annual gas prices by country across twenty geographies.

  • Inter-correlations between solar assets?

    Inter-correlations between solar assets?

    This data-file aggregates granular data from seven solar assets around Western Europe over a sample week. Absolute volatility is around 2-4% of nominal capacity every 15-minutes, while inter-correlations range from 60-90% depending on the distance between the different assets.

  • Data-centers: electricity use and demand shifting?

    Data-centers: electricity use and demand shifting?

    This data-file estimates data-centers’ electricity use and ability to demand shift. Large data centers how power demand in the range of 50-500MW. Around 40% of their electrical loads can demand shift, to help smooth out the volatility of renewables?
