stored at the customer level. We can expect 300 TB per year of meter data by 2012,
according to the FPL Group. The diagram from the Electric Power Research Institute via
Pike Research illustrates this exponential growth in data and the triggers driving key
inflection points.
As the Figure 1 illustrates, a broad array of drivers and sources for this data exists.
Utilities will be forced to grapple with many types of data in format and content.”
121.1 Explain how FortisBC proposes to deal with terabytes (TB) of data being
collected and stored at the customer level.
FortisBC has provided for the storage, retrieval and archiving of customer metering data for
seven years using the most cost effective storage available while preserving reliability and
security. Please also refer to the response to BCUC IR1 Q35.1.
Response:
121.2 What are the requirements for data retention in years?
Please refer to the response to BCUC IR1 Q121.1.
Response:
121.3 If Austin Energy’s data storage for 500,000 meters went from 20TB to 200TB or
400MB/meter/year, what is the expectation for the estimated increase in
FortisBC’s data storage requirements and its associated costs?
FortisBC currently has 21 GB (0.021 TB) of meter read data storage. Refer to response to
BCUC IR1 Q35.1 for storage requirements for the AMI solution (1.5 TB per year). The costs for
storage requirements for the AMI solution have been included in the overall project costs.
Response:
Yes.
121.3.1 Are these costs for data storage included in the AMI CPCN costs
and are they adequate?
