- RE targets of 30% and 50% are achievable in the power system as planned for 2030. Achieving these high RE targets will likely involve changes to how the power system is operated.
- System flexibility will contribute to cost-effective integration of variable RE.
- Achieving high levels of solar and wind integration will require coordinated planning of generation and transmission development.
- Strategic, economic curtailments of solar and wind energy can enhance system flexibility.
- Reserve provision may become an issue regardless of RE penetration. Additional qualified reserve-providing facilities (QFs), including from solar and wind generators, and/or enhanced sharing of ancillary services between the Luzon and Visayas interconnections will likely be needed.
