Canal-Top Photovoltaics for Supplying the Electricity Demand of a Fully Electrified Provincial Vehicle Fleet: A Case Study of Erzincan, Türkiye

Öz

This study assesses whether the annual electricity demand arising from the full electrification of the existing motor vehicle fleet in Erzincan, Türkiye, could be supplied by canal-top photovoltaic (PV) systems. A provincial-scale energy-balance framework was developed by integrating official vehicle stock data, national vehicle-kilometre statistics, electric vehicle energy consumption coefficients, tractor operating assumptions, local PV generation data, module specifications, canal length information, and investment cost benchmarks. The registered road vehicle fleet, excluding tractors, was estimated to generate 960.19 million vehicle-kilometres annually. Under full electrification, the corresponding traction-side electricity demand was calculated as 252.62–373.56 GWh/year, increasing to 265.25–392.24 GWh/year when charging losses were included. In the tractor sensitivity scenario, total grid-side demand increased to 310.51–528.00 GWh/year. Based on a specific PV yield of 1,550 kWh/kWp-year, meeting the road vehicle demand would require 171.1–253.1 MWp of installed canal-top PV capacity, 295,054–436,302 modules rated at 580 W, and 152.4–225.4 km of canal coverage. Including tractors increased these requirements to 200.3–340.6 MWp and 178.4–303.4 km. The required canal coverage corresponds to 20.4–40.6% of the reported 748 km irrigation canal network. The findings indicate that canal-top PV could theoretically supply the electricity demand of full provincial fleet electrification while supporting land-sparing renewable energy deployment, although detailed route suitability, grid integration, and techno-economic analyses are required before implementation.

Tam Elektrikli İl Taşıt Filosunun Elektrik Talebinin Kanal-Üstü Fotovoltaik Sistemlerle Karşılanması: Erzincan, Türkiye Örneği

Öz

Bu çalışma, Türkiye’nin Erzincan ilindeki motorlu taşıt filosunun tamamen elektrikli hale getirilmesinden kaynaklanacak yıllık elektrik talebinin kanal-üstü fotovoltaik (PV) sistemlerle karşılanıp karşılanamayacağını değerlendirmektedir. Resmî taşıt stoku verileri, ulusal taşıt-kilometre istatistikleri, elektrikli araç enerji tüketim katsayıları, traktör işletme varsayımları, yerel PV üretim verileri, modül özellikleri, kanal uzunluğu bilgileri ve yatırım maliyeti kıyas değerleri bütünleştirilerek il ölçeğinde bir enerji dengesi çerçevesi geliştirilmiştir. Traktörler hariç kayıtlı karayolu taşıt filosunun yıllık 960,19 milyon taşıt-kilometre hareketlilik ürettiği tahmin edilmiştir. Tam elektrifikasyon altında, buna karşılık gelen çekiş tarafı elektrik talebi 252,62–373,56 GWh/yıl olarak hesaplanmış; şarj kayıpları dâhil edildiğinde bu değer 265,25–392,24 GWh/yıl’a yükselmiştir. Traktör duyarlılık senaryosunda toplam şebeke tarafı talep 310,51–528,00 GWh/yıl’a yükselmiştir. 1.550 kWh/kWp-yıl özgül PV üretimine dayalı olarak, karayolu taşıt talebinin karşılanması 171,1–253,1 MWp kurulu kanal-üstü PV kapasitesi, 580 W gücünde 295.054–436.302 modül ve 152,4–225,4 km kanal kaplaması gerektirmektedir. Traktörlerin dâhil edilmesi bu gereksinimleri 200,3–340,6 MWp ve 178,4–303,4 km’ye yükseltmiştir. Gerekli kanal kaplaması, bildirilen 748 km’lik sulama kanalı ağının %20,4–40,6’sına karşılık gelmektedir. Bulgular, uygulama öncesinde ayrıntılı güzergâh uygunluğu, şebeke entegrasyonu ve tekno-ekonomik analizler gerekli olmakla birlikte, kanal-üstü PV sistemlerin il ölçeğindeki tam filo elektrifikasyonunun elektrik talebini teorik olarak karşılayabileceğini ve arazi koruyucu yenilenebilir enerji kurulumunu destekleyebileceğini göstermektedir.
