Power plants: average capacity?
This data-file aggregates granular data into the average capacity of different types of power plants: wind, solar, nuclear, gas, hydro, coal, biomass, landfill gas and geothermal. Energy transition is going to increase the number of inter-connections to the grid by 10-100x.

Solar volatility: second by second output data?
We have aggregated the volatility and power drops across an entire year of second-by-second solar data. Each day typically sees 100 volatility events where output drops by over 10%, and 10 events where output drops by over 70 events. Volatility also varies day by day.

Global electricity prices vs. CO2 intensities?
Retail electricity prices average 11c/kWh globally, of which 50-60% is wholesale power generation, 25-35% is transmission and 10-20% covers other administrative costs of utilities. The average CO2 intensity of the global average power grid is 0.45 kg/kWh. Variations are wide. And there is a -35% correlation between electricity prices vs CO2 intensities in different countries…

Gas power: does low utilization entail spare capacity?
The US has >400GW of large gas-fired power plants running at 40% average annual utilization. Could they help power new loads, e.g., 60GW of AI data-centers by 2030? This 5-page note shows why low utilization does not entail spare capacity, and in turn, estimates the true spare capacity for loads such as data-centers.

Global power price volatility tracker?
The volatility of power grids has doubled over the past decade from 2013-2024. This data-file tracks the percentile-by-percentile distributions of power prices, each year, in seven major grid regions (Texas, California, US MidWest, Australia, the UK, Germany, and Spain), as a way of tracking increases in global power price volatility. The growing volatility of power…

Water intensity of power generation?
The water intensity of US power generation averages 21 liters per kWh (5,600 gallons per MWH), but 95% of this total comes from evaporation at hydro reservoirs. Excluding hydro power, good estimates are that nuclear power uses 2.1 liters/kWh of water, coal power uses 2 liters/kWh and CCGTs use 1.2 liters/kWh, or less in some…

Hydro power: generation by facility, availability over time?
Hydro power generation by facility is tabulated in this data-file for the 20 largest hydro-electric plants in the US. The average facility achieves 43% availability, varying from 39% in hot-dry years to 51% in wet years; and from 33% at the seasonal trough in September-October to 53% at the seasonal peak in May-June. What implications…

Power grids: transmission and distribution kilometers by country?
This data-file aggregates power transmission and distribution kilometers by country, across 30 key countries, which comprise 80% of global electricity use. In 2023, the world contains 7M circuit kilometers of power transmission lines and 110M kilometers of power distribution lines. Useful rules of thumb are in the data-file.

Diesel power generation: levelized costs?
A multi-MW scale diesel generator requires an effective power price of 20c/kWh, in order to earn a 10% IRR, on c$700/kW capex, assuming $70 oil prices and c150km trucking of oil products to the facility. Economics can be stress-tested in the Model-Base tab.
