CEA Analytical Tool

CEA Power Dashboard

An analytical tool for tracking renewable energy market signals, capture prices and project economics in Serbia.

SEEPEX day-ahead market — hourly clearing prices, treated as the reference market price for Serbia.
ENTSO-E Transparency Platform — day-ahead prices (A44), actual generation per production type (A75 + psrType B16 solar / B19 wind), actual load, cross-border flows and installed capacity.
PVGIS (JRC, European Commission) — hourly PV output simulation based on coordinates, tilt and azimuth, used for solar generation profiles in the calculator.
AERS, EMS, Ministry of Mining and Energy, Energy Community — regulatory and policy context.
Demo data — synthetic SEEPEX-shaped series used wherever live data is not yet connected. Clearly labelled with a "Demo data" badge.

Baseload price

baseload = mean(hourly_price[period])

Simple average of all hourly prices in the selected period.

Peakload price

peakload = mean(hourly_price[weekday & hour ∈ 08–20])

Negative price hours

neg_hours = count(hourly_price < 0)

Solar capture price

capture_solar = Σ(price_h × solar_h) / Σ(solar_h)

Generation-weighted average price actually realised by solar.

Wind capture price

capture_wind = Σ(price_h × wind_h) / Σ(wind_h)

Capture rate

capture_rate = capture_tech / baseload

Below 100% indicates RES cannibalisation.

Merchant revenue

merchant_rev = Σ(generation_h × price_h)

LCOE

LCOE = (CAPEX + Σ OPEX_y/(1+r)^y) / Σ Gen_y/(1+r)^y

NPV

NPV = Σ CF_y / (1 + r)^y

IRR

IRR = r such that NPV(r) = 0

Solved by bisection over [-99%, +1000%].

Payback

first year where cumulative cashflow ≥ 0

DSCR

DSCR_y = EBITDA_y / debt_service_y

The dashboard treats negative prices as a meaningful market signal, not an error. Negative prices on SEEPEX became technically possible in May 2026.
Solar generation profiles use PVGIS hourly PV output for the selected coordinates and array configuration. Wind profiles use ENTSO-E actual generation where available, otherwise a clearly-marked estimate.
Capture price and capture rate calculations assume hourly profiles fully co-align with hourly market prices (no intra-hour resolution effects).
The Solar Project Calculator uses simplified financial mechanics: linear degradation, single tariff escalation, no inflation adjustment for OPEX. It is intended for indicative analysis, not bankable due diligence.
This tool provides indicative analysis only and should not be interpreted as financial or investment advice.
