Switch 2.0.6
In previous versions, the fixed costs of storage energy capacity (the MWh part of storage) from all possible build years were mistakenly applied each period, instead of only using the costs for the vintages that are still in service in the current period. This increased the apparent cost of storage by approximately (study length) / (storage life). This bug was introduced in version 2.0.0b3 and persisted through version 2.0.5, so results from earlier models will need to be updated.
This will be the last version of Switch to work in Python 2. It requires at least Python 2.7.12 and also works with Python 3.
