What makes REsurety’s tools the best for clean energy decision-makers?

  • Our products and services are backed up by best-in-class data from publicly available data and proprietary sources. We then add value to this data through our in-house models.

  • We focus on modeling generation at the hourly level to capture the diurnal and seasonal patterns of solar and wind generation.

  • Our price prediction system is designed to account for the relationships between weather, generation, market fundamentals, and price to accurately model revenue.

Generation & Price Modeling

Our generation modeling methodology captures the impact of a variety of elements on generation patterns. We start with long-term modeled weather data from third-party sources. We then improve upon those datasets by combining them with proprietary observations and in-house models. Multiple data sources and models are combined to form an ensemble that captures a large range of potential weather outcomes.

Our price modeling system uses machine learning to add various power pricing scenarios and weather conditions to forward power market curves. Other inputs like renewable penetration in the grid, energy demand, and gas prices are layered into the model to inform forecasts.

Shape Modeling

With generation and price modeling, we can determine the likely shape of a project. Shape describes the value of a project’s wind or solar generation relative to the average price of power, taking into account the relationship between when the project is producing and whether prices are usually high or low during that time. Shape is impacted by seasonal and diurnal correlations between generation and price, hourly market conditions, and the rate of renewable energy penetration in the market.

White Paper: Carbon Confidence in Climate Finance, as published by HASI

“LME is an important tool in assessing individual projects because seemingly identical renewable energy projects can have drastically different impacts on avoided carbon emissions.” CarbonCount is a decision tool that evaluates investments in U.S.-based renewable energy, energy efficiency, and climate resilience projects to determine how efficiently they reduce CO2 equivalent (CO2e) emissions per $1,000 of… Read more »

White Paper: Making It Count

Updating Scope 2 accounting to drive the next phase of decarbonization EXCERPT: Corporations are increasingly focused on reducing their carbon footprints by decarbonizing the electric grid. While solar and wind energy development have rightly been a mainstay of these efforts, there is growing consensus that producing more clean energy alone isn’t enough. To maximize grid… Read more »

Friends Don’t Let Friends Use 8760s …at least not for revenue modeling

Authored by Jennifer Newman, Vice President of Atmospheric Science Research, REsurety White Paper Executive Summary An “8760” (sometimes known as a “typical meteorological year,” or “TMY”) is a year-long hourly time series of expected generation for a wind or solar project.
