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…

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.

Thermal power plant: loss attribution?
This data-file is a simple loss attribution for a thermal power plant. For example, a typical coal-fired power plant might achieve a primary efficiency of 38%, converting thermal energy in coal into electrical energy. Our loss attribution covers the other 62% using simple physics and industry average data-points.

Ideal Power: Bi-Directional Bipolar Junction Transistors?
Bi-Directional Bipolar Junction Transistors are an emerging category of semiconductor-based switching device, that can achieve lower on-state voltage drops than MOSFETs and softer, faster switching than IGBTs, to improve efficiency and lower component count in bi-directional power converters. This data-file screens B-TRAN patents from Ideal Power.

Electric vehicle cost breakdown by component?
This data-file disaggregates the $30k total cost of a typical new ICE and the c$45k total cost of a typical new EV, as a sum-of-the-parts, across 25 cost lines. Drivetrain costs are similar at $8-9k each. The key challenge for the EV is the battery. The electric vehicle cost breakdown shows promise for improving power…

Solar capacity: growth through 2030 and 2050?
Forecasts for future solar growth have an unsatisfyingly uncertain range, varying by 3x. Hence this 15-page note discusses the future of solar. Solar capacity additions likely accelerate 3.5x by 2030 and 5x by 2040. But this creates bottlenecks, including for seven materials; and requires >$1trn pa of additional power grid capex plus $1trn pa of…

Offshore wind: installation vessels and time per turbine?
Wind turbine installation vessels are estimated to cost $100-500/kW in the breakdown of a typical offshore wind project’s capex. Total offshore construction time is around 10 days per turbine. Wind turbine installation vessel use averages around 5 days per turbine. Data from past projects are tabulated in this data-file.

US gas power: generation by facility over time?
US gas power generation by facility is broken down in this data-file, across 1,850 active gas-power plants, supplying 40% of all US electricity. Descriptive statistics are available in the summary tab, a state-by-state breakdown follows in the PlantsByState tab and underlying data on all 3,000 historical facilities are provided in the AllGasPlants tab.
