02 / KEPCO · Korea Energy Agency · Climate and Energy
Although the same business materials are used, the submission and review processes are conducted separately.
“Jeonpyeong” is an abbreviation for “Power System Impact Assessment.” KEPCO’s technical review provides the input data required for that assessment, and the completed assessment report is submitted by the project owner to the Ministry of Climate, Energy, and Environment. Consultation on energy use plans is a separate system.
First, verify based on the 10 MW benchmark.
Do not focus solely on this application; verify existing contracts and cumulative capacity expansions as well. Even if a project is not subject to a power system impact assessment, separately verify KEPCO’s supply review, consultations on energy usage plans, and building-related procedures.
Verify the capacity specified in the electricity service contract, the target region, the history of new construction and expansions, and whether any statutory exclusions apply. The November 28, 2025, pilot operation guidelines designate the entire country as the target region. Please reconfirm the applicable announcement at the time of submission.
IT load, transformer nameplate capacity (MVA), and daily consumption (kWh) should not be compared directly using a 10 MW benchmark. Determining eligibility or exclusion is not a procedure that the applicant can simply check off and complete on their own.
Korea Electric Power Corporation · Technical Review Team
Preparing for KEPCO’s Technical Review
This is the stage in which KEPCO reviews the impact of large-scale electricity demand on the power grid, and the project owner receives the results to incorporate them into the grid impact assessment report.
Contracts and finalizations prior to this stage
First, determine the scope of support for load and power supply plans and technical review applications for electrical design services. Selecting the company to prepare the power system impact assessment at the same time can help minimize omissions when transferring KEPCO’s response to the evaluation report.

What does the agency review?
We examine system equipment overloads following new supply and demand, the resulting increases in load, the time and cost required for reinforcement, and the ability to maintain appropriate voltage levels and ensure a stable power supply. The distance to the nearest substation alone cannot be used as a substitute for these findings.
Where do I submit it, and what do I receive in return?
On November 28, 2025, submit the PDF of the pilot operation application and attachments to the Grid Impact Assessment Division of the Grid Planning Office at KEPCO. After the application is received, fees are paid, and any required revisions are made, the project owner will receive the results of the technical review. Check the original text below for the latest submission address and forms.
Submitting a notice of intent and applying for a technical review are separate processes.
After receiving the notice of intent, attach the submitted materials to the application for technical review. A response to the technical review does not immediately constitute an electricity service contract or the completion of power transmission. If supply conditions change, subsequent evaluations, designs, and contract amendments must also be reviewed accordingly.
Ministry of Climate, Energy, and Environment · Power System Impact Assessment
Preparing the Power System Impact Assessment Report for Submission to the Ministry of Climate
This is the stage where an evaluation report—which combines KEPCO’s technical review materials with the project’s stability, economic benefits, and plans to mitigate grid impacts—is submitted and undergoes policy evaluation and deliberation by the Ministry of Climate.
Contracts and finalizations prior to this stage
Specify the scope of the Power System Impact Assessment (PSIA) preparation service, including the review of inclusion and exclusion criteria, technical review support, preparation of the assessment report, submission to the Ministry of Climate, and the process of addressing review comments and incorporating the results. Confirm whether support for electrical design and accounting/tax documentation constitutes a separate service.

What does the agency review?
We distinguish between technical items from KEPCO’s response, non-technical items regarding project stability and economic benefits, and policy items such as power self-sufficiency, policy compliance, and site selection. Since policy decisions are made by agencies and committees, preliminary calculations by private companies are not presented as official review scores or guarantees of approval.
Where do I submit it, and what do I receive in return?
On November 28, 2025, the project operator, Nae-Sang, will submit the evaluation report (HWP) and supporting documentation (PDF) separately to the Grid Operation Innovation Division of the Ministry of Climate. After undergoing policy evaluation, review by the subcommittee, and the Power Policy Deliberation Council, along with any necessary revisions, the operator will receive the results and details of the changes to be implemented. It is not assumed that KEPCO will automatically handle the process through to final acceptance.
Even facilities listed solely for scoring purposes are subject to actual implementation.
For planned ESS, xEMS, and on-site power generation, secure the necessary space, budget, and processes, and prepare all required installation and inspection documentation. As of November 28, 2025, emergency generators and PPA power demand are not included in the on-site power generation capacity. Application criteria and bonus point eligibility will be verified against the original text at the time of submission.

Preparing for Energy Usage Plan Consultations
This is a separate consultation process that involves not only determining which power source to connect to, but also planning how much energy the facility will consume annually and how to use it efficiently. Even if a facility is not subject to a power system impact assessment, it may still be subject to this consultation.
Contracts and finalizations prior to this stage
Enter into a contract with a firm that provides support for the development and coordination of energy usage plans, and specify that electrical, mechanical, and architectural designers must use the same load, operating hours, and cooling conditions. When outsourcing, verify the relevant qualifications, scope of services, and the scope of supplementary and implementation documentation to be prepared.

What does the agency review?
We review the feasibility of energy supply and demand, utilization efficiency, and conservation plans. While a data center’s PUE can be used as an explanatory metric, a single PUE value does not guarantee the completion of negotiations.
Where do I submit it, and what do I receive in return?
Once the project sponsor submits the plan, the Ministry of Climate receives it, followed by review, deliberation, and consultation by the Korea Energy Agency, and then the procedures for supplementary measures, implementation plans, and final reporting. The results of these consultations are incorporated into the building permit, design, construction, and post-construction management.
We determine eligibility by distinguishing between MW and annual kWh.
For the “Facilities” category in the Industrial Complex Guide, the criteria are at least 5,000 toe/year of private fuel or 20 million kWh/year of electricity, and at least 2,500 toe/year of public fuel or 10 million kWh/year of electricity. Separate criteria apply to the “Business” category, which includes cities and industrial complexes. Annual consumption is not determined solely based on a facility’s maximum power capacity.
Please also divide the amount on the quote into four columns.

Before signing a contract, these six points are documented and agreed upon.
- Scope: At what stage is the process—notification of plans, technical review support, evaluation report, deliberation and revisions, or design and construction?
- Completion Criteria: Does this refer to the delivery of the report, its receipt, or the process through the submission of revisions and receipt of the results?
- Cost of changes: Additional fees apply in the event of changes to the address, capacity, voltage, or operator, or in the event of resubmission or reevaluation.
- Responsibility and Deadline: Date the project owner provided the data, date of the company’s deliverables, agency representative responsible for revisions
- Fees and Actual Expenses: Whether institutional costs, travel expenses, and VAT are included, and payment terms by phase
- Handover: Ownership and usage rights to original drawings, calculations, submitted documents, and responses from agencies, as well as settlement procedures in the event of project termination
We manage these as contracts that allow us to verify actual work performed, the basis for decisions, and liability for remediation, rather than as contracts that promise permits or supply approvals.

The pre-operation inspection, building occupancy permit, KEPCO transmission connection, and integrated commissioning each involve different verification processes. Ensure the sequence of these steps is correct in the commissioning plan, and obtain all necessary results before commercial operation begins.
FAQ
Frequently Asked Questions When Preparing to Launch a Business
What do “IT Load,” “Power Supply,” “ESS,” and “xEMS” mean?
“IT Load” refers to the power consumed by IT equipment such as servers, while “power supply” refers to the electricity received from external sources such as KEPCO. ESS stands for Energy Storage System, and xEMS refers to a system that measures and controls a facility’s energy usage. MW denotes power capacity, while kWh and MWh represent the amount of energy consumed over a specific period. PUE is an efficiency metric calculated by dividing the facility’s total energy consumption by its IT energy consumption.
Do I need to sign a contract with the construction company first?
In practice, the first step is to select a design firm to review the architecture, site location, and power demand, and to confirm the necessary evaluations and supply conditions. The construction contractor should be selected before entrusting tasks such as formal application submission, cost estimates, and construction; however, it is not necessary to finalize a contract for all construction work from the outset.
Are the KEPCO technical review, the power system impact assessment, and the Ministry of Climate Change review the same thing?
The KEPCO technical review is a stage in which technical data on the power grid is provided. The company preparing the power system impact assessment and the project owner use this response and supporting project documentation to finalize the assessment report, submit it to the Ministry of Climate, and receive the results of the policy evaluation and deliberation. All submission and result documents must be retained.
Does completing the power system impact assessment also mean that the energy usage plan consultation is finished?
No. The criteria, review items, and required documentation differ between the power system impact assessment and the energy usage plan consultation. Verify the applicability of each, use the same design input values, but manage the submissions and results separately.
If I sign a contract with a power system impact assessment provider, does that also serve as a contract with KEPCO?
No. A contractor agreement is a contract to handle data preparation and application support, whereas a KEPCO electricity service contract is a power supply contract between the applicant and KEPCO. It is important to distinguish between the authority to submit applications on behalf of others and the party that is the ultimate contracting entity.
If I include PPAs or emergency generators in the Ministry of Climate Change’s evaluation, will I receive bonus points?
November 28, 2025: For the pilot operation, PPA power demand and emergency generators are excluded from the calculation of on-site power generation capacity. Renewable energy, energy efficiency measures, and energy storage systems (ESS) must also be separately verified to ensure they comply with the applicable requirements and standards for installation, operation, and implementation.
Does commercial operation begin immediately after receiving a building permit or passing the pre-operation inspection?
We verify compliance with relevant inspections—such as building occupancy permits, pre-service electrical inspections, and fire safety inspections—as well as the commencement of power supply by KEPCO. Following this, we determine when to begin commercial operation after ensuring alignment with operator acceptance criteria, integrated commissioning, and the safety management system.
How long should the total duration be, and what should the estimated cost be?
It varies depending on the site, scope of evaluation, design maturity, grid reinforcement, equipment delivery schedules, and supplementary measures. The agency’s review period is not presented as the total development period; instead, costs—including KEPCO’s review fees, contractor service fees, facility contribution fees, and construction costs—are calculated separately, along with schedules for each prerequisite condition.
Now it’s time to determine the order of my business sites.
Please prepare the address, target IT capacity, planned start date, and any responses or permits you have received from KEPCO. We will organize the necessary reviews and assign responsibilities based on the information provided.
