Solar hits new milestone with over 1,000 megawatts
now online on five islands served by Hawaiian Electric
Nearly 4,700 rooftop solar systems installed in 2021; 92,500 now online
HONOLULU, Jan. 13, 2022 – A total of 1,019 megawatts of solar capacity has been integrated
into Hawaiian Electric grids as of Dec. 31, 2021, a major milestone as the company works to cut
carbon emissions from power generation 70% by 2030.
At the end of 2021, there were 92,504 systems with 1,019 MW (1 gigawatt) of solar capacity
and 121 MW of battery storage on the five islands served by Hawaiian Electric. About 312 MW
of that solar capacity is from grid-scale facilities with contracts to sell power to the utility.
In 2021, 4,656 private rooftop systems with 51 MW of capacity were added to the company’s
five island grids, which now have a total of 92,504 systems. This represents an increase of 5.3%
over the 2020 total of 87,848.

“This accomplishment owes its success to the eagerness of our customers to be part of the
solar movement, dedicated solar contractors and Hawaiian Electric’s work to smooth the way for
more rooftop solar and to create new customer options,” said Lani Shinsato, Hawaiian Electric
Customer Energy Resources co-director.
“We’re working to encourage even more participation through programs such as Quick Connect
and Battery Bonus, working closely with the solar industry and other partners to provide
customer opportunities in grid service programs,” she said. “We’ll need maximum customer
participation to help drive action on climate change.”

Twenty-one percent of Hawaiian Electric’s residential customers have rooftop solar. On the five
islands served by Hawaiian Electric, 32% of single-family homes have rooftop solar; on O‘ahu,
it’s 37%. Hawai‘i has among the highest rates of rooftop solar adoption in the nation.
With a commitment to cut carbon emissions from power generation 70% from 2005 levels by
2030, Hawaiian Electric’s Climate Change Action Plan includes the addition of 50,000 rooftop
solar systems on homes and businesses over the next nine years. Almost all new systems
today include energy storage, giving customers greater control over their energy use and saving
them money while supporting the stability and reliability of island grids.
With the urging of Hawaiian Electric and the solar industry, the Public Utilities Commission has
raised capacity limits on popular rooftop solar programs, effective Jan. 18.
 For O‘ahu, the capacity limit for Customer Grid Supply-Plus has been raised to 70 MW
from 50 MW, and Smart Export has increased to 35 MW from 25 MW.
 For Maui County, CGS+ capacity has been increased to 12 MW, up from 7 MW, and
Smart Export has been raised to 10 MW from 5 MW.
 For Hawai‘i Island, CGS+ has been raised to 17 MW from 15 MW, and Smart Export is
now 20 MW, up from 10 MW.
In addition, Hawaiian Electric hopes to soon launch shared solar, the newest phase of
community-based renewable energy, to provide a way for renters, apartment residents and
small businesses and organizations unable to install private rooftop solar to benefit from solar
electricity generated on their island.
