Deal Capture

SimEnergy facilitates efficient and accurate entry of deals, products, counterparties and other relevant information. A configurable deal workflow is included in the ETRM to facilitate segregation of duties based on permissions and notifications configured for each user. Deal limits and delegations are an integral part of this process to assist your organisation in delivering good governance.

Spot Analytics: Position Reports

SimEnergy provides a flexible notional position chart where you can; – group deals by node, instrument, book, strategy or counterparty; – include or exclude any deal; – display in interval-level resolution or aggregate by day, week, month, quarter, year or whole period; – display in flat, peak and off-peak or by working and non-working 48 part profiles;
– stack deals by instrument against a retail or generation position.

Forward Analytics: Forward Price Curve

SimEnergy has creation of interval-level Forward Price Curves to use in MtM that fit the users’ selection of market prices and historical half-hour shapes.

Calibration: Load Forecasting

SimEnergy uses historic meter data to calculate load profiles for retail loads and generation. This energy trading and risk management solution can handle up to 80% missing data with load profiles calculated for each month and ‘missing’ months copied from the closest month of valid data. SimEnergy calculates the average, minimum, maximum and standard deviation load profiles for each interval for up to 3 day-types for each set of metered data.


Instruments include LGCs, STCs, VEECs and ESCs. Environmental certificates can be created from historical meter readings for generation and retail, MtM can be produced from an Environmental Forward Curve and Inventory and Cashflow reports can be produced.


SimEnergy provides for settlement calculations and invoice management in a controlled workflow for OTC derivatives, views of dated payments and invoice creation for upcoming payments.


SimEnergy has system administrator controls access, permissions and notifications for each user in SimEnergy. The system administrator can also define custom fields and configure database connections, shared folders and other configurable settings.


Design and customise your own reports based on the simulation and valuation engines integrated into SimEnergy with the results written to the database. This facilitates integration with external systems via the provision of a managed suite of database views.

Spot Analytics: At-Risk Metrics

SimEnergy has multi-region Earnings-at-Risk (EaR), Cash Flow-at-Risk (CFaR) and Value-at-Risk (VaR) are calculated by SimEnergy. EaR and CFaR calculations can use interval-level price simulations created using MRJD or Discrete methodologies or prices provided by the user. Metered load and/or generation dispatch can also be simulated and discount curves and credit spreads incorporated in the valuation. VaR is calculated using volatilities and correlations calculated from historical prices.

Forward Analytics: Mark-to-Market (MtM)

SimEnergy can MtM using interval-level volume and price profiles. The interval-level profile can incorporate various load profiles including minimum, average, maximum and simulation and the interval-level Forward Price Curve can be based on historical prices, current market prices or supplied by the user. MtM can also be calculated for Futures, OTC, Environmentals and Options based on closing prices which are stored against each Product. The MtM can be calculated on a Net basis or By Deal on a Full-term or Balance of term basis.

Forward Analytics: Initial Futures Margin

SimEnergy initial Futures Margin using PC Span are calculated.
