Using internally developed, proprietary models for contract and physical asset valuation, LEI has supported clients in securing financing for large-scale investments, preparing regulatory filings, and providing expert courtroom testimony. Our analytical tools include models for price forecasting incorporating game theory, real option valuation, Monte Carlo tools, and sophisticated statistical analysis. LEI ‘s Continuous Modeling Initiative (CMI) draws on these tools, as well as the latest market data, to provide industry participants with regularly updated 10-year forecasts of key electricity markets, which are available through London Economics Press.
POOLMod has been constantly upgraded over two decades of use, and it has been applied worldwide to provide a highly flexible foundation for a range of modeling activities.
LEI has created comprehensive tariff models based on the principle of full cost recovery for many clients in the electricity and water sectors. These tariff models are grounded in regulatory economic principles and global best practices. We’ve also drafted working papers reviewing the mechanics and principles of rate/tariff setting, and developed quantitative tariff models that account for differences between distinct business units (e.g. electricity, water, and wastewater business lines).
Furthermore, LEI has developed user-friendly manuals to accompany the tariff models, which provide clear guidelines on how to use and navigate the models, assumptions utilized for the end-user tariff calculations, locations of key inputs and assumptions, and directions on how to find the main outputs. The manuals also show how revenue requirements are built up for each business line.
In addition to our Tariff modeling services, LEI has also proposed tariff filing processes, and filed tariff petitions with applicable regulatory authorities for approval.
LEI professionals have applied sophisticated third-party models to estimate macroeconomic impacts of investments, rate changes, and environmental events. Models used include:
