Our Capabilities

Big Data

Underlying the financial performance of any wind farm is a vast sea of data.  Each hour, thousands of data points are generated and collected for an individual wind farm, ranging from turbine-level operational performance to weather conditions, energy pricing and grid congestion. 

REsurety's proprietary data processing platform enables us to collect, organize and extract intelligence from that sea of data, at an unprecedented scale.

Power Markets

Renewable energy projects benefit from a huge advantage: their fuel is free. However, when and how much of that fuel will materialize at any given time is unknown - creating an entirely new risk for power markets to understand and manage. 

Built on top of our proprietary database of historical project performance, REsurety has pioneered the analytical systems and contract structures needed to understand and manage the fuel risk of the future: the weather.

Resource Assessment

The energy yield of a wind or solar farm depends on a range of complex factors related to weather, site conditions, and project design, etc. 

REsurety's proprietary models - trained and tested on extensive observed data - reduce the uncertainty inherent in predicting long term energy yields so that efficient risk market capital can be utilized to hold and diversify renewable energy yield risk.
