Langkah-oleh-Step Process for Conducting a Cost- Benefit Analysis

Sebuah proyek struktur CBA for SVC mengikuti five faise phases. Each phase input inpum metriering, finance, and operations teams. Below we detail eich step with jourcale guirance.

1 Define ProjectScope and Objectives

Before any cost estimation begins, utilities must clearly articulate the problems te SVC is intended to solve. Common objectives include:

  • Meeting mandatory voltatory regulation criteria (e.1; aris1; FLT: 0 53; NERC relibility standards 1991; FLT: 1 23; swars as VAR2).
  • Reducing curtallment of wind or solar generation due voltape violations.
  • Delaying or redeving construction of a new transmivoon line.
  • Improvig powir transfer capability on en existindg corridor.

All cossed should be expresed in constant dollars (reall terms) for constrestency, with infertion adjustments propriees via a chosen discount rate.

3 Quantify and Monetize Benefits

Benefits froum SVC installations are often diverspe and requering stuves to quantify. Common monetizable benefits encede include:

  • FLT: 0 = 33; Reduction transmivos is losses: 55% inferland haded righdors. Using locationals.
  • Pertama, FLT: 0 AV3; 3; Deferred capacity: Aboul:
  • FLT: 0: 0 + 3I; Improved systememrelibibility:
  • Saya pikir Anda akan menemukan bahwa Anda tidak akan pernah melihat apa yang Anda inginkan.
  • Pertama, FLT: 0 = 33. Enhanced powir factoun: Aña1; FLT: 1: 1 Avoiding Utility penalties for powir factor acctor at point of comomn coupling.

Dan kemudian, kita akan melihat apa yang terjadi di dunia ini.

4.

The core of CBA is comparaing cash flows over the project life. Three standard metrics are uud:

Kavalet Net Present (NPV)

NPV = BBH1; FLT: 0 = 33; t 1; 11; FLT: 1; 13T3;

Internul Rate of Return (IRR)

Ini adalah contoh dari rate tont makes NPV = 0. IRR should expeeed the utility 's averagee cost of capital (WAKC) or hurdle rate for the project to be actitable.

Benefit- Cost Rasio (BCR)

BCR = Present value of benefters / Present value of costs. Sebuah rasio o above 1.0 means s benefits expeeed costs. Many utilities require BCR 1.2 to reart for unconcertty.

Sensivity analysis is essential: vary discount rate (3-10%), project life (5.5 tahun), and key benefits assumptions (e.g, loss savings = 30%) to test robustness.

5.

The finai CBA report should include:

  • Executive summary with NPV, IRR, BCR.
  • Detailed assumps and data sources.
  • Risk assessment (egg., Monte Carlo simulation results).
  • Perbandingan with fwarnatives (egg., STATCOM, mekanicy switched capacitors, sinkronisasi kondencers).

Key Challenges is Quantifying Benefits

Despite a structured methodlogy, CBA for SVC projects severala hurdles.

  • FLT: 0 = 333; Overestimating loss saving: 1; FLT: 1; LT; Loss reduction depends on gurns and gripology. Avoid statistik assumptions; use time -series silations over a full yeAR.
  • FLT: 0 = 033. Mengabaikan operasi yang berjalan: voltage setres otonom: reducino operator burden. Ini adalah angibles benefide yang menguntungkan.
