f)
Attain 35% RE share by 2030 and 50% by 2040;
Attract investments in RE thru innovative business
models
Empower End-Users in using roof-mounted RE systems
Decongest transmission & distribution thru
decentralization
Offer alternative compliance mechanism to EEC Act &
Government Energy Management Program (GEMP); and
Streamline processes and requirements of roof-mounted
solar projects

Supply Contingency Option
○ Electricity End-Users with Self-Generation RSF of above
100 kW
Lease-to-Generate Option
○ All energy generated shall only be exported either to the
DU or to the Grid,
Restricted Peer-To-Peer Energy Trading
○ applies to contiguous area where RSPs, Prosumers, and
Consumers electricity trading within and/or among
themselves
○ RSPs provide trading platform & operate P2P trading
where excess electricity may be sold to DU or Grid;

Arrangements
○ Supply Contingency Option
■ UPOU Constructs System with own funds and uses electricity
generated to fully offset consumption
○ Lease to Generate Option
■ UPOU Constructs and sells all electricity to MERALCO at
average Generation Cost
○ Restricted Peer-to-Peer
■ Power Developer constructs system and sells power to UPOU
but UPOU invests in Detailed Architectural and Engineering
Design (DAED)

Analysis
Engineering Economic Analysis Results
1.
UPOU building a new Roof-mounted Solar Facility is economically feasible
a.
b.
2.
3.
Offsetting own use under Supply Contingency Option is the best option (highest NPV)
Selling all generated power to the Distribution Utility (DU) under the Lease to Generate
option is the next best option
Leasing roof space to a Rooftop Solar Provider for supply of electricity to
the DU under the Lease to Generate option is the worst
Where only MOOE is available to UPOU, the Restricted Peer to Peer option
is economically feasible with a positive NPV and the highest IRR
Thank you!
