Abstract:
Abstract. This paper presents the new and now open-source version
2.1 of the REgional Model of INvestments and Development (REMIND). REMIND,
as an integrated assessment model (IAM), provides an integrated view of the
global energy–economy–emissions system and explores self-consistent
transformation pathways. It describes a broad range of possible futures and
their relation to technical and socio-economic developments as well as
policy choices. REMIND is a multiregional model incorporating the economy
and a detailed representation of the energy sector implemented in the
General Algebraic Modeling System (GAMS). It uses non-linear optimization to
derive welfare-optimal regional transformation pathways of the
energy-economic system subject to climate and sustainability constraints for
the time horizon from 2005 to 2100. The resulting solution corresponds to the
decentralized market outcome under the assumptions of perfect foresight of
agents and internalization of external effects. REMIND enables the analyses of
technology options and policy approaches for climate change mitigation with
particular strength in representing the scale-up of new technologies,
including renewables and their integration in power markets. The REMIND code
is organized into modules that gather code relevant for specific topics.
Interaction between different modules is made explicit via clearly defined
sets of input and output variables. Each module can be represented by different
realizations, enabling flexible configuration and extension. The spatial
resolution of REMIND is flexible and depends on the resolution of the input
data. Thus, the framework can be used for a variety of applications in a
customized form, balancing requirements for detail and overall runtime and
complexity.
