   Asrene®SP4808 Chandra Asri Group Supports Indonesia's New
          Renewable Energy Mix Based on Geothermal

Jakarta, February 6th 2024 – PT Chandra Asri Pacific Tbk (Chandra Asri Group), a leading
chemical and infrastructure solutions company in Indonesia, supports the national target for
renewable energy mix (EBT) through collaboration by providing infrastructure raw materials
for the Geothermal Power Plant (PLTP) project. The company provides Asrene®SP4808
material with a special formulation that can be manufactured into High-Density Polyethylene
(HDPE) pipes with PE 100 grade for geothermal field facilities. Asrene®SP4808 is also a local
resin that has obtained Indonesian National Standards (SNI) certification and has the highest
Domestic Content Level (TKDN) in Indonesia.

HDPE pipes with special formulations applied in geothermal fields can replace the use of steel
pipes while offering relatively lower material costs, installation costs, and maintenance or total
ownership costs. Compared to steel pipes, HDPE pipes using Asrene®SP4808 raw materials
with special formulations have the advantage of being more resistant to corrosion and
abrasion, as well as offering flexibility and elasticity, allowing them to adapt to the contours of
the geothermal field area.

Geothermal energy is a renewable and sustainable energy source that is environmentally
friendly, as it does not produce significant greenhouse gas emissions and can meet electricity
needs by harnessing the available heat from the earth's core in various regions. Geothermal
power plant projects also contribute to achieving the renewable energy mix target according
to the National Energy General Plan (RUEN), which aims for 23% by 2025 and 31% by 2050.

Supriyanto, the General Manager of Technical Service and Product Development at
Chandra Asri Group, stated, "Asrene®SP4808 owned by Chandra Asri Group, is an SNI
certified resin qualified as PE 100 with the best long-term strength and has the highest
Domestic Content Level (TKDN) in its class. The provision of high-quality raw materials also
reflects the company's commitment as Indonesia Growth Partner in providing infrastructure
solutions for the development of more environmentally friendly renewable energy in this
country."

The use of HDPE pipes with special formulations has previously been implemented at the
Hamiding Geothermal Field in North Maluku, where they were applied in facilities supporting
drilling water supply. Similarly, at the Wayang Windu Geothermal Field in Pangalengan, West
Java, HDPE pipes were utilized in facilities distributing mixed condensate water with a
temperature of 55°C to injection wells. From these applications, HDPE pipes have proven to
be a reliable choice for geothermal facilities due to their reliability and minimal maintenance
requirements once operational.

The Geothermal Power Plant (PLTP) process utilizes heat generated from within the earth to
produce electrical energy. The process begins with drilling geothermal wells to extract steam
generated from heat sources within the earth. The steam is then directed to turbines, where
its pressure and temperature are used to drive the turbines and generate mechanical energy.
This mechanical energy is then converted into electrical energy through generators. After
passing through the turbines, the steam is condensed back into water and then recirculated
back into the earth through injection wells.
