Process Efficiency, Losses and Heat Rates

The document outlines how to input process efficiency data in LEAP, detailing the use of percentage efficiency, heat rates, and energy losses. It provides typical values for steam generation and hydropower and specifies the application of these methods to storage and distribution systems.

• Process efficiency data in the software can be entered using three distinct methods: percentage efficiency, heat rate, or percentage energy losses, with the specific method determined by the module properties.
• The default efficiency method calculates the ratio of energy outputs to feedstock energy inputs, excluding co-product energy recovery. Typical values include approximately 33% for base-load steam generation, while 100% is often used for hydropower, renewable electricity generation, and imports.
• Alternative data entry methods include the heat rate, which is the amount of feedstock fuel needed per unit of energy produced (common for electricity plants), and percentage energy losses, which is particularly useful for transmission and distribution systems.
