      abstract     = {This short communication paper provides an update on our
                      original battery storage paper for the year 2019 [1]. It
                      contains detailed information about the markets for home
                      storage systems (HSS), industrial storage systems (ISS), and
                      large-scale storage systems (LSS) in Germany. The HSS market
                      has continued its growth of the last few years. We estimate
                      that 60,000 new HSS, with a total battery power of around
                      250 MW and storage capacity of 490 MWh, were installed in
                      2019. This adds up to a total of 185,000 HSS, with a power
                      of about 750 MW and storage capacity of 1,420 MWh by the end
                      of 2019. The specific prices of lithium-ion HSS have fallen
                      by more than $50\%$ in recent years. From 2018 to 2019,
                      prices for mid-sized HSS between 5 kWh and 10 kWh decreased
                      by $7\%,$ to around 1,100 €/kWh. The new database of the
                      German Federal Network Agency, “MaStR”, already shows
                      over 90,000 HSS registrations in total by May 1st 2020 and
                      is growing continuously. It also yields some insights into
                      the ISS market, which thus far has mostly been uncharted.
                      Approximately 700 ISS with storage capacities greater than
                      30 kWh have already been registered. The registered ISS add
                      up to a cumulative power of around 27 MW and storage
                      capacity of over 57 MWh by the end of 2019. However, the
                      current state of the ISS database still does not allow for
                      comprehensive estimates of the overall German ISS market.
                      With respect to the LSS market, in 2019, only nine new LSS
                      projects came into operation with a battery power of 54 MW
                      and storage capacity of 62 MWh, indicating a strong decline
                      in market growth. The new installations add up to a total of
                      68 LSS in oper-ation, with an accumulated power of 460 MW
                      and a capacity of about 620 MWh.},
