A separate committee under the Smart Grid Interoperability Panel is working on guidelines for how to migrate from SEP 1 to SEP 2 meters and home networks. It expects to release a first draft of its work as early as June.
"Millions of smart meters have been deployed that I would characterize as pre-standard, and we want to make sure people get full value of them," said George Arnold, national coordinator for Smart Grid standards, speaking at a conference here.
The SGIP group will deliver guidelines that address issues such as use of gateways and other migration strategies. It may also try to influence aspects of the SEP 2 standard still in progress, said Steve Widergren, head of the SGIP.
Concerns about the smart meter road map have delayed some smart grid projects. "This needs to stop being a blocking issue," said Widergren.
The SEP 2 effort is one of the most high profile of a broad range of standards for smart grids that extend from the home to back-end transmission and generation systems and networks that connect them. A recent report estimated the cost of upgrading to a smart grid could hit $476 billion.
The National Institute for Standards and Technology aims to publish before the end of the year an updated release of its January 2010 framework of smart grid standards. "A lot of work has gone on since then," said Arnold.
The update, a draft of which is now online, is the first to be reviewed by the SGIP, a broad industry and government collaboration set up in late 2009. The draft includes work on more detailed architectural concepts, smart grid test and certification processes and updates on a number of standards completed and still in progress.
A section on cyber-security for the smart grid will include a three year plan with milestones on the topic. A cyber-security group organized by NIST now includes more than 800 members in eight working groups.
"We are always looking for volunteers because the workload is extensive," said Marianne Swanson, who coordinates the smart grid security work at NIST. "We have looked at more than 25 standards just since September, and this is an area where we need the most help because we are almost drowning in standards to review--they just keep coming in," she said.
