IRENA estimates that the deployment of large-scale storage systems in energy markets will increase by 40 percent each year until 2025. Battery energy storage systems are one of the most popular technologies at the moment because:
It is a solution to overcome the obstacles caused by the intermittent production of renewable energy.
BESS contributes to providing reliable and cheaper electricity in isolated grids and off-grid communities that would otherwise rely on expensive and polluting fossil fuels such as diesel.
NREL, in their report, ‘Cost Projections for Utility-Scale Battery Storage’, said that the prices of batteries have decreased considerably and will continue to. From 2010 to 2019, battery prices had decreased by 87 percent, according to Bloomberg New Energy Finance. Predictions say that by 2030, prices will be reduced by 42.7 percent.
In RatedPower’s Renewable Energy and Solar Research Report: What’s in store for 2022, +100 solar industry professionals shared their thoughts about the market. They believe that battery storage and green hydrogen have the biggest potential to be successfully implemented around the world by 2030, with 64 percent of them identifying batteries. Looking ahead, more than half of respondents pointed to storage options (57 percent) as needing more resources in the coming year.
“This pvDesign new feature is the first step to provide a complete hybrid PV - BESS solution to our clients” said Ignacio Álvarez, Product Manager at RatedPower. “The synergies between storage and PV are highly consistent. The predictable daily on and off cycle of solar photovoltaics is well aligned with the battery charge and discharge needs. With the increase of renewables, battery storage has a critical role to play to successfully balance load 24/7”
RatedPower customers can now design an AC-coupled BESS. Through its BESS software module, customers can include storage into new solar designs or into already existing projects.
Traditionally, BESS sizing is based on PV plant estimated rated power - regardless of available land or BESS requirements (i.e. capacity optimisation or electrical requirements). RatedPower has inverted the approach to make the most of the area the BESS is placed in and take into account the supply chain duration or capacity optimisation.
pvDesign automatically locates the battery containers and the power conversion stations in the defined site. It will take into account the hours of operation of the batteries, calculate the length of the cables or perform earthworks. It will also size the interconnection facility.
As is usual with pvDesign, the software generates the required documentation for the basic engineering of an AC coupled BESS:
Layout,
Bill of materials
Design report.
pvDesign also provides the energy that is available to charge the batteries.
