HOMER 2.75 generates warnings when the percentage of renewable energy in a system gets high enough to require more detailed modeling. The new zinc bromine flow batteries deliver steady backup power for hours and have a longer life span than tradition lead-acid batteries. Flywheels deliver short bursts of power instantaneously to level the delivery of energy in a hybrid system, when additional generation needs to be brought on-line suddenly. Increased renewable energy adds to the requirement for “spinning” or standby operating reserve to bridge periods of variability in wind or solar power sources.



The new version of HOMER includes the ability to model new storage technologies, such as flywheels and zinc bromine flow batteries, both of which will allow designers to develop larger systems that have a higher contribution from renewable energy. Boulder, CO (PRWEB) HOMER Energy announced the release of HOMER v2.75 today, the first commercial release of the software since it was licensed from the National Renewable Energy Laboratory.
