Rule 21 Enables Capstone Green Energy to
Comply with New California Power Generation Communication and
Control Requirements
Capstone Green Energy Corporation (NASDAQ: CGRN), a global
leader in carbon reduction and on-site resilient green Energy as a
Service (EaaS) solutions, announced today that the C65 and C200
inverters have received certification for California Rule 21 tariff
requirements. The certification builds upon Capstone’s previous
successes with UL1741 SA and prepares inverters for meeting the new
UL1741 Supplement B.
“Our Capstone engineering team works continuously to stay ahead
of the growing number of new global grid interconnect requirements
and standards,” stated Darren Jamison, President and Chief
Executive Officer of Capstone. “Country specific standards continue
to evolve, and while they are starting to adopt similar standards
in certain areas, they are different enough to require detailed
software changes and extensive testing in our state-of-the-art grid
simulation lab,” added Mr. Jamison.
The controller integrated solution includes a gateway module
that facilitates two-way utility connections for remote monitoring,
as well as dispatching updated settings for inverter output
response. The gateway acts as a communications protocol converter,
allowing a utility connection based on IEEE 2030.5 and the Sunspec
Common Smart Inverter Profile (CSIP) to read and write data using
the proprietary Capstone protocol integrated into the microturbine
Smart Inverters. The gateway is also certified as a standalone
device in the event that a full feature controller is not
required.
“Staying current on the evolving global grid interconnect
standards is no small task,” said Don Ayers, Vice President of
Technology. “In the case of the Rule 21 certification, we utilized
combined resources within the company to ensure that we could
complete this project, while continuing to make progress on other
challenging grid interconnect projects, particularly for the German
market. The success of this project was truly the result of
cross-departmental collaboration, along with maintaining close
relationships with our external partners,” added Mr. Ayers.
At the turn of the century, traditional grid standards were
still primarily focused on ensuring the safe adoption of power
generation equipment. However, as photovoltaic (PV) and wind
generation accelerated in Germany in the 2000’s, these standards
evolved to guide the impact of inverters on grid integrity. The
evolution of grid standards has expanded to every country,
including the United States, Italy, Australia, and Great Britain,
where standards have been developed to meet unique grid
infrastructure needs. More recently, these standards continue to
advance with the adoption of utility monitoring and control of
distributed generating assets, such as Rule 21.
“While we have a small team dedicated to certification and
surveillance, we have been able to partner with different
Nationally Recognized Testing Laboratories (NRTLs) to stay on top
of constantly evolving grid requirements that are promulgated,”
said Victor Kong, Director of Product Engineering at Capstone Green
Energy. “Ultimately, Capstone can meet these standards for the
majority of customer sites, which only involves a quick software
update with minimal downtime and no hardware changes.”
