2017 Utility Energy Storage Market Snapshot

SEPA is introducing our expanded annual survey efforts which includes, for the first time, energy storage deployment data. SEPA has collected survey responses from 115 utility respondents who serve 57% of the customer accounts in the country. The survey found that a  total of 207 megawatts (MW), 257 megawatt hours (MWh) was deployed in 2016. 

  • Top 10 energy storage utility rankings by MW, MWh and Watts per Customer
  • 2016 U.S. energy storage market deployment by market segment and utility type
  • State Energy Storage commitments and incentive programs
  • Utility programs testing the capabilities of battery storage


Cyber Security Metrics for the Electric Sector

Quantification of cyber security has been a long-standing challenge in the utility industry. When one implements a new cyber security solution that costs $500,000, how can the value of the investment be correctly quantified? When a policy was changed to enforce more complex passwords, what is the incremental security value achieved through the change? This challenge comes from the fact that there have not been comprehensive, standardized security metrics widely adopted by the industry. If we had such metrics, a utility could easily calculate and understand the value of security investments in concrete terms. A utility could definitively state, "the change improved the Protection Score by 10.4% and overall security metrics by 6.2%".

EPRI’s Cyber Security Metrics for the Electric Sector project addresses these needs by developing a practical set of security metrics that represents the status of a utility’s security posture. Initiated in 2015, the EPRI research project is expected to deliver a full set of proposed metrics that will provide measures of the effectiveness of security controls.


Electrical Storage Systems: Efficiency and Lifetime

This application note discusses the technical aspects of battery energy storage system design and operation and their influence upon system efficiency and lifetime. The various roles of electrical energy storage systems are discussed first in order to gain appreciation of the way these systems are used. This is followed by a discussion of the most common battery technologies and their aging mechanisms. Factors which affect the efficiency and lifetime of power electronics are also discussed, since power converter(s) and associated switchgear are essential elements and determine in part the performance of energy storage systems.
