European gas and power model: natural gas supply-demand?
European gas and power markets will look better-supplied than they truly are in 2023-24. A dozen key input variables can be stress-tested in the data-file. Overall, we think Europe will need to source over 15bcfd of LNG through 2030, especially US LNG.

Molten Carbonate Fuel Cells: CCS plus Power? The Economics?
Molten Carbonate Fuel Cells could be extremely promising, generating electrical power from natural gas as an input, while also capturing CO2 from industrial flue gases through an electrochemical process. We model competitive economics. Our model runs of 18 input variables, which you can stress-test.

Solar power: the economics?
Levelized costs of solar electricity are estimated at 7c/kWh in our base case, but can realistically range from 4-40c/kWh. This data-file is a breakdown of solar costs, as a function of capex, opex, insolation, curtailment and decline rates. Solar can be highly competitive, up to 35-50% of many power grids.

Coal-to-Power Project Economics
Greenfield coal-to-power economics vary markedly by region. IRRs can reach 30% in emerging markets with low capex costs, high utilization and no carbon prices. But they fail to return their capital costs under developed world air standards and $25/ton CO2 pricing. Please download the model to stress-test the economics.

Levelized cost of electricity: stress-testing LCOE?
This data-file summarizes the levelized cost of electricity, across 35 different generation sources, covering 20 different data-fields for each source. Costs of generating electricity can vary from 2-200 c/kWh. The is more variability within categories than between them. Numbers can readily be stress-tested in the data-file.

Wind power: decline rates?
This data-file aggregates wind generation by facility, across the US, at 1,400 wind farms, going back 20-years. Wind power decline rates average 1% per year, then possibly accelerate to 3-4% per year in years 10-20. However wind generation is also noisy, typically varying +/- 7% YoY. This matters for the economics and ultimate share of…

Wind power: decline rate conclusions?
This 4-page PDF presents our conclusions from tabulating the ‘decline rates’ of 1,215 US wind power plants, which have reported data to the US EIA. US wind generation profiles are not dissimilar from well-managed oil and gas fields; some projects may suffer 2% lower IRRs versus forecasts if they have not factored in declines; and…

Solar power: decline rates?
This data-file tabulates the ‘decline rates’ of 3,200 US solar power plants going back to 2001. The median YoY decline is found to run at 2.5%. However, the data are volatile and variable. Hence this data-file gives full granularity, asset by asset. Decline rates could detract c4pp from the IRRs of future solar projects and…

Energy efficiency of motors and power generators?
This data-file estimates the efficiency of electric motors and power generators, using specific examples and data-points. This matters as there are around 50bn motors in the world, consuming c45% of global electricity. Efficiency ratings are generally high, above 90%, although lagging and non-optimized motors can be in the 70-80% range.

Combined heat and power turbines: market sizing?
The purpose of this data-file is to ballpark the ultimate potential market size for combined heat and power systems in the US (CHPs). Our build-up looks across five main categories: large power facilities, large industrial heating facilities, landfill gas, electric vehicle charging and smaller-scale commercial and multi-family usage.
