distribution substation in order to define purchase amount, and to prevent
reverse power from the distribution system into the transmission system
which would cause power losses. Therefore, to prevent such a problem,
power generation from renewable energy sources must be managed by the
distribution operators - Metropolitan Electricity Authority (MEA) and Provincial
Electricity Authority (PEA) -
In the future, the renewable purchase schemes would play a vital role in
implementing the AEDP, thus, the Energy Regulatory Commission (ERC) will be responsible
for monitoring the country’s renewable energy status, and revising the AEDP by situation. As
a result, private investors would have a clear picture of the country’s renewable energy
development.
3.3 Principles and Directions for Firmed Cogeneration SPPs with PPAs
expiration date during year 2017-2025
The National Energy Policy Council (NEPC) approved principles and directions for
firmed cogeneration SPPs with PPAs expiration date during year 2017-2025, the details are as
follows:
1. Criteria for Firmed Cogeneration SPPs with PPAs expiration date during
year 2017-2025
Cogeneration power plants could generate both electricity power and useful heat
in the form of steam. Therefore, it is advantageous for industrial estates not to invest on
unnecessary own boilers. Moreover, Replacement of expired Cogeneration SPPs and
construction of the news are ease because of community acceptance and the existing
infrastructure exploitation. Thus, the criteria for Firmed Cogeneration SPPs with PPAs
expiration date during year 2017-2025 are as follows:
1.1 In case of PPA renewal for old technology cogeneration SPPs, the tariff
structure will be renegotiated because the investor has already recovered construction
costs.
1.2 In case of construction of new cogeneration SPPs, it is necessary to
promote cogeneration SPPs as Distributed Generation (DG) in order to lessen losses in
transmission and distribution system by the following measures:
