PowerSimmTM Gas Storage

PowerSimmTM Gas Storage integrates physical asset operations with market conditions and hedging strategies to provide integrated physical and financial risk assessment and portfolio valuation.

Ascend's model utilizes advanced stochastics with dynamic programming to analyze, optimize and value the operation of gas storage assets with both intrinsic and extrinsic value.

PowerSimmTM Gas Storage simulates meaningful uncertainty in future forward and spot price markets, and values operation of the physical asset relative to simulated prices to achieve the most complete representation of asset value.  The dynamic modeling capabilities makes this an industry-leading tool.

Get the most complete representation of asset value.

Ascend provides accurate valuations and enhanced operations by modeling physical asset attributes and market prices simultaneously and in rich detail.


Complex seasonal or volumetric ratchets, reserve constraints, seasonally fluctuating capacity, and critical operating costs are all captured to realistically represent the asset's operation and precisely determine its value.


Users can choose between multiple valuation models which provide additional understanding of the asset's valuation under a range of operating strategies.

PowerSimmTM Gas Storage Analytic Features

PowerSimmTM Gas Storage offers superior modeling of uncertainty in asset operations, allowing detailed asset constraints to be reflected in assessment reports.

Ascend's gas storage model reflects a detailed description of the asset attributes.  The PowerSimmTM Gas Storage model is particularly well suited for complex gas storage systems with multiple interdependent constraints.

PowerSimmTM Gas Storage incorporates detailed configuration options, such as individual reservoir characteristics, to better reflect the trade-off between spot and forward markets during injection and withdrawal seasons.


PowerSimmTM Gas Storage's advanced solver applies approximate dynamic programming to capture meaningful uncertainty in future market prices and load conditions.


This uncertainty can be used to assess the likelihood of various future regimes and to form a better picture of expected and potential future revenue generated by the gas storage asset.

Better models. Better decisions.
