ABOITIZ Power Corp. plans to install
and commission a 48-megawatt battery energy storage to beef up its ability to
sell backup power.
AboitizPower Chief Operating Officer
Emmanuel Rubio said preliminary work is under way. “We are doing a study
on it technically. We have to work closely with NGCP [National Grid Corp. of
the Philippines], as well. If all goes well, we can have it ready by
2019,” he said.
The battery energy storage will be
put up within one of the power firm’s power plants, the location of which has
yet to be identified.
The Energy Regulatory Commission
earlier classified battery energy storage as a new source of ancillary
services, frequency control ancillary services, particularly contingency
reserve, and secondary reserve.
Across the world, regulators and
system operators are increasingly turning to advanced energy storage as a
solution for ancillary and other grid services due to its flexibility, speed of
response, scalability and rapidly decreasing costs.
“What we would like to do is to be
better in providing contingency reserve, and we’re looking at battery as a
solution to actually be better, that would enhance our ability to offer
contingency reserves given that we already have that contract today,” Rubio
explained.
Ancillary services constitute
standby power supply that can be tapped in case the regular supply falls short
of the requirement.
Aboitiz has sealed a number of
ancillary agreements with NGCP in the past.
Ancillary services are meant to
support the transmission of capacity and energy from resources to loads while
maintaining reliable operation of the transmission system. These services are
essential in ensuring reliability in the operation of the transmission system
and, consequently, in the reliability of the electricity supply in the Luzon,
the Visayas and Mindanao grids.
Regulating reserve is the capacity
allocated to cover inter- and intra-hour variations in demand, while
contingency reserve refers to the capacity allocated to cover the loss or
failure of a generating unit or a transmission line in order to maintain
balance between generation and load.
Thanks for sharing this great article! That is very interesting I love reading and I am always searching for informative information like this. Being a Canadian advanced Battery Energy Storage Ontario and specializing in smart distributed energy storage solutions, we help industrial areas.
