summary & overview

Comparison with LEAP by the Stockholm Environment Institute

LEAP is not an integrated planning tool with an advanced capacity expansion model but a so-called ‘general equilibrium model’ that helps users understand the interaction between interdependent markets. General equilibrium models generate a different insight and are very limited in their use to plan an energy systems investment or a technology transition path.
