Recent technology cost forecasts underestimate the pace

A team of researchers from the College of Cambridge, College Faculty London, College of Oxford, and College of Brescia/RFF-CMCC European Institute on Economics and Atmosphere made a preliminary systematic assessment of the relative efficiency of potential price forecasts from expert-based strategies and models. -based strategies.

They specifically focused on one expert-based technique – knowledge eliiations – and 4 model-based strategies that put prices both as a cumulative put in capacity or as a time operation. The results of this comparison are published in PNAS.

Accurately predicting electricity prices is a necessity for the design of robust and cost-effective decarbonization insurance policies and enterprise plans. The way forward for these and various applied sciences is notoriously difficult to predict, resulting in the methodology being conceived, developed, codified, and deployed that is part of a fancy adaptive system and is a part of interconnected actors. Made of and Establishment

A range of possible forecasting strategies have been developed and used to generate estimates of future information prices. Two high-level varieties of approaches have been used most frequently to generate quantitative forecasts: expert-based and model-based approaches.


Broadly, expert-based approaches include alternative methods of obtaining data from educated people, who may have differing opinions and/or information regarding the relative importance of mixed drivers of innovation and how they are developed.

Consultants make implicit decisions regarding the underlying drivers of change when presenting their forecasts and may take into account every public detail about observed values ​​in addition to data that will not be largely obtainable or codified. The knowledge-based approach is sometimes a supply of data available to analysts when information is not collected on a given knowledge—as is the case with most increasingly applied sciences.

In contrast, model-based approaches use a number of variables from explicitly obtainable observed information to estimate the effect of a total set of drivers of innovation on information prices, assuming that the pace of change so far Will be a great prophet. Sooner or later the pace of change.

“The high availability of data on future power information allowed us to conduct a priori systematic comparison of the relative efficiency of probabilistic information generated by completely different expert-based and model-based methodologies with potential prices” notes the senior. and corresponding author Prof. Diaz Anadon, professor of local weather change coverage at Cambridge College and director of the college’s Center for Atmosphere, Vitality and Pure Useful Resource Governance.

“Such comparisons are important to ensure that researchers and analysts have additional empirical evidence in the underlying valuation fashion, value benefit analysis and broad coverage design efforts”.

That means attempting to evaluate one of these comparisons and better understand the various forecasting strategies should develop more widely among modelers and forecasting practitioners, as more information is on the market. “Our evaluation is aimed at a selected time period and the correlated power of applied science, so although our results are meant to present strategies that underestimate technological progress in this area, additional analysis is needed”.

Pro. Anadon led by Dr. Jing Meng, a Lecturer from the College Faculty London at Bartlett College, Dr. Rupert Method, a postdoctoral researcher at Oxford Martin College, and Prof. Dr. Rupert Method from the Legislature Division of Brescia College. Wrote articles with E. Vardolini. and affiliated to the RFF-CMCC European Institute on Economics and the Atmosphere. Pro. Anadon and Prof. Vardolini was the work package deal leader at INNOPATHS, the European Union’s H2020 venture, which financed almost all of the research work.

Several important results emerge from this assessment.

As Oxford College’s Dr. Method explains, “A comparison of expert- and model-based forecasts observed in 2019 prices over a short period of time (maximum of 10 years) suggests that the model-based approach outperformed the informed. In particular , the fifth-ninety-nine percentile range of the four model-based approaches was more likely to include observed value than EE forecasts. Of the many model-based strategies, some captured 2019 and higher prices than others. paid attention to.

“Also”, College Faculty London’s Dr. Meng noted, “The 2019 mean of model-based forecasts was close to the 2019 value typically observed for 5 of the six applied sciences.
