Energy markets inherently exhibit far greater risk compared to traditional financial markets such as equities and bonds. Energy commodities in general display differentiating characteristics when compared to other asset classes which make conventional approaches to valuation, hedging and risk management a challenge for even the talented of risk managers. Market fundamentals play a larger impact with both supply and demand factors causing price behaviour to be very uncertain and at times volatile when compared to the price behaviour of other asset classes. Weather, infrastructure failure and fuel shortages coupled with rapidly changing demand for electricity on a daily or even hourly time scales make accurate price forecasting a constant concern. This white paper aims at analysing some of the quantifiable risks facing integrated energy companies and how fundamental optimisation software coupled with systematic and robust analysis can help decision makers manage risk and optimise their energy portfolio to retain their competitive advantage.
