Storage Valuation

Extrinsic Valuation of Energy Storage for Batteries and Natural Gas

Increase profitability and reduce risk by choosing Quantego’s stochastic storage optimization. Optimal extrinsic valuation of storage for electricity or natural gas: optimize injection and withdrawal decisions, calculate optimal delta hedges, price storage contracts, calculate cashflow-at-risk and value-at-risk.

Quantego’s storage valuation solution offers the full range of methodologies: spot-based valuation, rolling intrinsic valuation, extrinsic valuation, which gives energy traders a complete view of the value of storage based on a broad set of different models.

 A detailed model of price evolution, hedging, and storage operation

Quantego’s storage valuation models offer the full range of methodologies: spot-based valuation, rolling intrinsic valuation, extrinsic valuation, which gives energy traders a complete view of the value of storage based on a broad set of different models.
  • Options for stochastic price models include (a) a one-factor, mean-reverting spot price model, (b) a risk-neutral model of term structure dynamics (multivariate Black model), (c) Quantego's empirical model of the daily evolution of the price forward curve.
  • The operational decision model captures (a) calendar-based storage limits, (b) fill-dependent injection and withdrawal rates (ratchets), (c) trading in monthly, quarterly, yearly futures and spot.
  • The model integrates hedging decisions and storage operations by modeling the trade-off between risk aversion and market impact cost of futures products with limited liquidity.  

  A ready-to-use graphical user interface

The model is available as ready-to-use yet highly customizable software solution deployed through QUASAR® Cloud.

Users can import and manage input data, execute optimization runs, calculate storage value, value-at-risk, delta positions, create interactive charts and reports, as well as export result data and easily share it across the organization. QUASAR® Cloud can be obtained as subscription service or set up on-premise via AWS VPC. Learn more about QUASAR Cloud

  The world's most powerful stochastic programming solver

The model is driven by the powerful QUASAR® stochastic programming solver that combines the latest advancements in machine learning and mathematical optimization. QUASAR®’s highly efficient algorithms can solve the most complex stochastic-dynamic programming problems with hundreds of time stages, thousands of variables and millions of possible outcomes at an unprecedented speed.

Success Story

Our storage valuation model for incomplete markets for natural gas has been published in the European Journal of Operational Research. Instead of risk- neutral pricing, the model uses a physical model of the possible evolution of the price forward curve. Extensive backtests of the model on historical future price data from Henry Hub showed higher profits than with a rolling intrinsic approach.
