As was the case in the U.S. solar industry five to ten years ago, deployment of grid-tied energy storage is highly uneven from quarter to quarter, with ups and downs driven by large utility-scale projects coming online. During the second quarter of 2015 the completion of a 31.5 MW lithium-ion system in Illinois drove the market to its second-highest quarterly volume to date at 40.7 MW. However, under these headline numbers other trends are emerging, as GTM Research and the Energy Storage Association's Q2 U.S. Energy Storage Monitor explores. Over the course of 2014, 65 MW of grid-tied energy storage was deployed in the United States. In the first two quarters of 2015 this has reached 46.5 MW - almost 80% of the previous year's volume. Including the project in Illinois, most large-scale energy storage projects over the last two and a half years have been in the 13-state PJM Interconnection grid. Report author Ravi Manghani, who serves as GTM Research's senior energy storage analyst, says that this is largely due to PJM's implementation of Federal Energy ...Den vollständigen Artikel lesen ...
