Facility requirements
Review electricity consumption, load profiles, operating hours and site conditions.
FINANCIAL STRUCTURING · PPA
Energy investment through a PPA
A power purchase agreement (PPA) defines how capital, ownership, operations and electricity purchases are structured. 365Energy connects engineering, commercial planning and delivery to suit each facility.

01THE PPA MODEL
HOW IT WORKS
How does a PPA work?
A PPA can separate the decision to use electricity from the decision to own the assets. The facility purchases electricity under a contract, while investment and operating responsibilities follow the project structure.
Project structure & PPA
Define investment principles, ownership, responsibilities and electricity purchase terms for the project.
Electricity under contract
The system supplies electricity to the facility. Consumption and payment follow the agreed arrangements.
ENERGY FLOWOn-site system → Facility → Electricity consumed on site
COMMERCIAL FLOWFacility → Electricity payments → Under the PPA terms
02ASSESSING SUITABILITY
START WITH DATA
Is a PPA a good fit?
Suitability depends on electricity demand, site conditions, the planned period of use, capital priorities and energy goals.
Electricity demand
Is there enough information on consumption, load profiles and operating hours to assess the options?
Site conditions
Are the roof or available space, structural conditions and technical constraints suitable for further assessment?
Planned period of use
Do site-use rights and operating plans support a long-term contract structure?
Investment priorities
How does the business want to balance upfront investment, cash flow, ownership and control?
Energy goals
Which electricity cost, renewable energy and ESG requirements should take priority?
03INVESTMENT STRUCTURE
COMPARE YOUR OPTIONS
PPA, EPC or EPC-F?
The main differences between EPC, EPC-F and PPA are capital investment, ownership, control of the assets and operating responsibilities.

04ALLOCATING RESPONSIBILITIES
DEFINE THE SCOPE
Clear responsibilities from the start
Before agreeing on a proposal, clarify who provides the data, who invests, who owns the assets and who handles engineering and operations.
| SCOPE | FACILITY | INVESTOR / PPA PARTNER | 365Energy |
|---|---|---|---|
| Load & site data | Provide inputs | — | Review |
| Technical assessment | Coordinate | — | Within the project scope |
| Engineering design | Coordinate | Under the project structure | Within the project scope |
| Project investment | Under the proposed arrangement | Under the contract | Within the confirmed scope |
| Asset ownership | Under the contract | Under the contract | Within the confirmed scope |
| Operations, maintenance & monitoring | Coordinate | Under the contract | Within the agreed scope |

05DELIVERY PROCESS
FROM ASSESSMENT TO OPERATIONS
The PPA delivery process
The process moves from initial data to feasibility assessment, commercial structuring, contracting, delivery and operations.
Data review
Electricity bills, load profiles, site information and operating conditions.
OUTPUT · Basis for project assessment
Technical assessment
Technical feasibility, the basis for system sizing and key technical constraints.
OUTPUT · Preliminary technical proposal
Commercial structuring
Investment arrangements, PPA principles and allocation of responsibilities.
OUTPUT · Proposed structure
Contracting & preparation
Agree on the scope, terms and requirements before implementation.
OUTPUT · Readiness for implementation
Design & construction
Design, procurement, construction, QA/QC, testing and acceptance.
OUTPUT · Completed system
Operations & management
Monitoring, O&M and reporting within the agreed scope.
OUTPUT · Long-term operations management
06DELIVERY CONTROLS
KEY CHECKPOINTS
Controls throughout delivery
Each stage needs a clear checkpoint to reduce gaps between commercial decisions and technical execution.
Four points to confirm
Each checkpoint clarifies inputs, scope and responsibilities before the project moves to the next stage.
Technical basis
Clarify load data, site conditions and technical assumptions before structuring the proposal.
Commercial scope
Define ownership, responsibilities, payment arrangements and contract conditions for each project.
Execution controls
Manage design, QA/QC, testing and acceptance within the agreed delivery scope.
Lifecycle management
Link monitoring, O&M and reporting to operating responsibilities once the project is in service.
07FREQUENTLY ASKED QUESTIONS
BEFORE THE ASSESSMENT
PPA questions answered
The information below is general. Specific terms must be confirmed against the project, contract and applicable regulations.
01How do PPA and DPPA differ?
On this page, PPA refers to an on-site project model. DPPA is a direct power purchase mechanism between renewable energy generators and large electricity users under Decree 57/2025/ND-CP, as amended by Decree 243/2026/ND-CP. Whether a project falls under or needs to use the DPPA mechanism must be reviewed against its connection model, participating parties and the regulations in force at the time of assessment.
02How is the PPA electricity price determined?
There is no single price that should be assumed for every facility. An assessment needs to consider technical conditions, investment structure, contract duration, operating scope and allocation of responsibilities.
03How is the PPA contract term determined?
The contract term is part of the commercial structure. It needs to be assessed alongside site-use conditions, investment arrangements, project economics and the parties’ long-term responsibilities.
04What happens when the contract ends?
End-of-term arrangements depend on the agreed terms and the project’s ownership structure. Asset transfer should not be assumed unless it is specified in the contract.
05What if the facility’s electricity demand changes?
Changes in demand can affect system sizing, self-consumption and the commercial viability of the proposal. Current data and planned operational changes should therefore be considered from the outset.
