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?
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.

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 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 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?
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?
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?

Wind energy: beyond good and evil?
Wind economics are not good or bad in absolute terms. They depend on capacity factors, which average 26% globally, but can range from 10% to 60%. In the best locations, levelized costs are below 4c/kWh. Hence this 16-page note explores global wind capacity factors and updates our wind outlook by region throgh 2050.

India: electricity demand and power grid over time?
India’s electricity demand is growing by 6-8% (+100-140 TWH) per year, but 75% of the total still comes from coal, which has itself grown at a 5% CAGR over the past half-decade. Wind and solar would need to grow 4x faster than 2023 levels for thermal generation just to flatline. What implications and opportunities for…

Midstream gas: pipelines have pricing power ?!
FERC regulations are surprisingly interesting!! In theory, gas pipelines are not allowed to have market power. But they increasingly do have it: gas use is rising, on grid bottlenecks, volatile renewables and AI; while new pipeline investments are being hindered. So who benefits here? Answers are explored in this 13-page report.
