A measure of the variation of one day’s temperature against a standard reference temperature, typically 65° Fahrenheit (18° Celsius). Degree days are used as a basis for temperature-related weather derivative deals. There are both cooling degree days (CDDs) and heating degree days (HDDs). For example, a firm takes out a 30-day CDD swap with a reference temperature of 65°F, and the average temperature on each day is 70°F. The company is then due 150 (30 x 5) degree days multiplied by the sum of money agreed for each degree day. If the firm had taken out an HDD swap, it would have owed the same amount of money.
The Energy Risk Glossary, now in its eighth edition, provides an at-a-glance explanation of the myriad specialised terms and acronyms used in energy trading and risk management.
This year, the guide has been updated by Aviv Handler of ETR Advisory. Energy Risk would like to thank him for his input into this edition, which benefits greatly from his valuable experience and insight into energy markets.
The fast-changing nature of these markets means much has changed since our last edition – almost 200 new entries and revisions have been made this year. Reflecting the increasing importance of regulation, definitions of the Markets in Financial Instruments Directive (MiFid) and the Ljubljana-based Agency for the Cooperation of Energy Regulators (Acer) make it into the glossary for the first time. A focus on improving back-office infrastructure and mitigating counterparty risk is also apparent from the inclusion of terms such as ‘portfolio reconciliation’ and ‘portfolio compression’.
The glossary is extensively cross-referenced, making for easy and thorough searches. We hope you find it useful.
