Load Forecasting

SimEnergy uses historic meter data to calculate load profiles for retail loads and generation. SimEnergy 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 half hour for up to 3 day-types for each set of metered data.

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 half-hourly resolution or aggregate by day, week, month, quarter, year or whole period

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

Mark-to-Market (MtM)

SimEnergy can MtM using a half-hour volume and price profiles. The half-hour profile can incorporate various load profiles including minimum, average, maximum and simulation and the half-hour 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.

At Risk metrics
