Release v0.6.4

Version 0.6.4 is packaged up and ready for download on PyPI and conda-forge! Highlights of this version are new group constraints that add a range of flexibility. For example, the cost_var_max group constraint allows flexible emissions limits on a per-region basis (assuming emissions are modelled as a cost class). The demand_share_max or demand_share_per_timestep_max group constraints allow limiting groups of technologies (e.g., variable renewables, or legacy generators) to a maximum on a model-wide basis or for groups of locations, on average or in each individual time step, respectively. → Read more...

New year, new website

We have a new logo and website! Replacing the dusty old static site with little informational value and little visual appeal, the new website is the first landing point for information about Calliope and its applications. In particular, we now have a model gallery with on existing Calliope models (which are also a good place to start learning when building a new model). More models will be added to the gallery in the near future. → Read more...
