The newest from Bloomberg on battery prices - which continue to fall at a steady rate.
With large amounts of investments being made in capacity for making batteries around the world this learning curve will continue and may in fact accelerate.
In the electricity space - watch for projects which are designed/engineered so that initial batteries installed match the interconnection capacity and then more battery duration is added later. So for example, with a 250MW interconnection - 250MW/250MWh are installed initially to quickly provide valuable capacity to the market. With prices declining, more duration can be added later at a cheaper cost - let's say an additional 750MWh 2 years later.
