This week’s “Top 5” includes a battery plant expansion in Europe, a case study from Flexgen Power Systems, simulation results from NREL on demand charge management, a new chairman of the management board for Saft, and Tesla proving its interest in stationary storage.
1. “Leading German battery maker BMZ has started work on a €45 million expansion of its manufacturing plant near Frankfurt, that will quadruple its production capacity to around 5GWh of energy storage capacity a year”
“According to energy storage market expert Tobias Rothacher, the timing of the German battery maker’s expansion is spot on, with the latest figures from the KfW development bank showing the number of PV-battery system installations increased by 50 per cent over the last year.”
2. Flexgen Power Systems published a case study on storage for North American drilling customers. The study claims that using Flexgen 1.2 MW storage system instead of adding another genset on oil and gas drills could enable $2455 savings per day.
3. “The Energy Department’s (DOE) National Renewable Energy Laboratory (NREL) has used the Battery Lifetime Analysis and Simulation Tool (BLAST) to confirm that energy storage for demand-charge management can deliver attractive economic benefits.[…] The results revealed that, in the absence of incentives, small battery systems reducing peak demand by 2.5 percent offer the most attractive return on investment.”
“Batteries for demand-charge reduction are most cost effective under today’s rate structures when configured for higher power-to-energy ratios, targeting discharge durations from 30 minutes to one hour,”
4. Ghislain Lescuyer was appointed Chairman of the Management Board of Saft.
5. Tesla is hiring 78 people to develop its stationary energy storage team.
