A.

The entire lifecycle of a solar power plant can be divided into five stages.


STEP 01   Project Development
Development and Lease Agreement for the Plant Site → Basic Design → Feasibility Analysis → Obtaining Power Generation Business Approval → Signing Power Purchase Agreement (PPA) 


STEP 02   Project Financing
Establishment of Capital Structure and Financing Plan → Insurance Enrollment for the Power Plant → Negotiation of Guarantee Conditions → Signing Financing-Related Contracts 


STEP 03   Construction
System Design → Material Procurement → Construction 


STEP 04   Power Production with O&M
Power Generation and Sales → Power Plant Maintenance 


STEP 05   Repowering
After the End of the Plant’s Lifespan, Rebuilding a New Power Plant on the Same Site

A.

The revenue structure consists of the electricity sales price and the REC (Renewable Energy Certificate) sales price under the RPS (Renewable Portfolio Standard) system.

- SMP (System Marginal Price) + REC (Renewable Energy Certificate issued by the Korea Energy Agency).
- Annual revenue: Annual power generation × (ⓐ SMP + ⓑ REC × ⓒ Weight factor). 


With the recent rise of the RE100 initiative, the PPA (Power Purchase Agreement) method is becoming more widespread. This method involves directly selling electricity to consumers through renewable energy suppliers, who act as intermediaries.

There are various types of PPA contracts, and if you leave an inquiry, we can assist you in proceeding with an optimized contract tailored to the status of your customer's power plant and the characteristics of the buyer.


A.

The design of a solar power plant is generally divided into civil/structural design and electrical design.

ⓐ Electrical design: High-efficiency configuration and design according to electrical safety regulations.
ⓑ Structural design: Establishing a structural plan, reviewing structural calculations, and designing the optimal structure.
ⓒ Civil design: Managing development activities, ensuring soil stability, and designing optimal drainage and civil works.


A.

According to Article 22 of the Electrical Safety Management Act, the owner or occupant of electrical facilities is required to appoint an electrical safety manager, with a fine of 5 million KRW for non-compliance. 

For electrical facilities with a capacity of 1MW or more, the electrical safety manager must be directly employed. For facilities under 1MW, the appointment can be delegated as follows:

ⓐ Appoint an employee of the Korea Electrical Safety Corporation directly.
ⓑ Appoint through a legally registered electrical safety management company.

However, for facilities between 1MW and 3MW, an electrical safety manager may be appointed through an electrical safety management company instead of direct employment, provided that a remote control and monitoring system is installed.


A.

Electricity market prices are determined one hour in advance, based on the forecasted power demand curve from the previous day and the supply curve formed by power generators participating in the supply bidding. The market price for each hour is set at the point where the supply curve intersects with the demand curve, satisfying system constraints.

ⓐ Since April 2, 2001, electricity has been traded like a commodity due to changes in the power industry.
ⓑ There are multiple suppliers (power companies) and a single buyer (KEPCO).
ⓒ The power supply quantity is determined based on the power demand.


A.

Electricity market prices can be checked directly on the Korea Power Exchange (KPX) website. Additionally, you can access daily updates through the Blackwood Renewables Kakao Channel.

By simply subscribing to the Kakao Channel, you can view various information, including prices. We encourage you to join and stay informed.



A.

Renewable Portfolio Standard (RPS) 

RPS is a system that mandates obligated entities to supply a certain amount of renewable energy as part of their total power generation (Renewable Portfolio Standard).

* Obligated entities: Companies that own power generation facilities of 500,000 kW or more (excluding renewable energy facilities), such as major electric companies, with a total of 22 entities.  

* 1 REC = 1 MWH


A.

Facilities eligible for Renewable Energy Certificate (REC) issuance are those verified by the head of the New and
Renewable Energy Center and registered in the management system.

principle) Renewable energy facilities that began commercial operation on or after January 1, 2012.

exception) Facilities that began commercial operation before January 1, 2012, such as solar power facilities under the RPS pilot project.


A.

 Spot Market Trading: A bidding system through the Korea Power Exchange (KPX) where REC prices are determined by auction.

 Fixed-Price Competitive Bidding System: A 20-year fixed-price contract based on SMP (System Marginal Price) + REC through agreements with power generation subsidiaries. This bidding is conducted twice a year (once in the first half and once in the second half) by the Korea Energy Agency.


A.

ⓐ To prevent various safety accidents in advance.
ⓑ Regular maintenance is necessary because the power generation and revenue of the plant are proportional, and any disruption in production leads to a halt in profitability.
ⓒ To detect problems in the power generation equipment early and take preventive measures at a lower cost.
ⓓ For the post-management of the power plant.
