Electric Vehicle Deployment and Carbon Emissions in Saudi Arabia: A Power System Perspective

A power system model for Saudi Arabia was built to quantify the carbon emission implications of deploying electric vehicles (EVs) within the Kingdom. The model represented the four operating regions in the Kingdom as segmented by the electricity regulator.

The Potential of Distributed Solar PV Capacity in Riyadh: A GIS-Assisted Study

Rooftop solar photovoltaic (PV) systems, commonly referred to as distributed generation (DG) solar systems, can play a central role in the energy mix for sustainable cities. As with all forms of power generation, DG carries technical, financial, policy, and market implications that impact utilities, governments, businesses and other stakeholders.

Techno-Economics of Solar PV on Mosque Rooftops: Results from a Pilot Study in Saudi Arabia

There are an estimated 3.5 million mosques worldwide. The relatively large surface area of most mosque rooftops and their ubiquity in the Muslim world make them excellent candidates for solar photovoltaic (PV) installations. Muslims congregate for prayers at mosques five times a day: at dawn, noon, afternoon, sunset, and evening. Because these times are governed by the sun, they change chronographically within the year, according to the season, but are perpetual. As such, mosque electricity load profiles are highly predictable across each year and experience limited annual variation.

Estimating the Learning Curve of Solar PV Balance-of-Systems for Over 20 Countries

The capital cost of a solar photovoltaic (PV) system comprises the module and balance-of-systems (BOS). The latter refers to everything else that is needed to make the solar system functional including cables, mounts, labor, etc. While modules are priced internationally, the BOS is countryspecific. Price developments of modules, which have been thoroughly studied in literature, followed an 80 percent learning curve (LC). On the other hand, research on the LC for BOS has not been as extensive.

Reporting LCOE for Solar PV: Apples to Apples Comparisons

Solar energy is expected to be an integral technology in the creation of a low-carbon future. Hence, as photovoltaics (PV) installations continue to grow at an exponential rate, a better understanding of the generation costs of this relatively young industry is necessary in order to assess its competitiveness versus conventional sources. Using an extensive data set of generation costs for solar technology.

Adding Photovoltaics to the Saudi Power System: What are the Costs of Intermittency?

Intermittent generation from wind or photovoltaics (PV) imposes a cost on the power systems in which they are deployed. These costs vary regionally due to different fuel costs and ramping flexibility of existing grid capacities. With 2015 as a reference year, we examine the costs of PV intermittency and costs of integration to power utilities in Saudi Arabia, using a least-cost approach for the power utilities. The operational facets of PV integration to grid operators will be more pronounced with higher PV penetration, so, to focus on system operation, we exclude the capital costs. The excess of the price paid to new PV generators over the current average consumer tariff would also have to be covered by the utility, and will depend on the details of the power purchase contracts.

Changing Competitive Landscape: Transition Policy’s Blind Spots

For the past two to three decades, and particularly in the wake of the Great Recession, clean energy transitions have been sold as a three-for-the-price-ofone policy: creating “green collar” jobs to get the unemployed back to work, using domestic resources to reduce dependence on imported fossil fuels, and all while reducing carbon emissions. The first of two implicit goals of this “three-fer” was the development of local, high tech industries supported by policy-driven domestic demand for wind and solar equipment. These high tech industries would, in turn, deliver the second goal of driving down the costs of clean energy technologies to the point where they would no longer require policy support.

Electricity Transmission Formulations in Multi-Sector National Planning Models: An illustration using the KAPSARC Energy Model

The purpose of this study is to assess policy-relevant effects of incorporating a more proper representation of electricity transmission in multi-sector national policy models. This goal is achieved by employing the KAPSARC Energy Model (KEM), which is the first publicly available large-scale energy policy model for Saudi Arabia. Past studies using KEM have examined industrial pricing policy, residential energy efficiency, the prospects of power generation technologies and residential electricity pricing. These studies have shown that under certain fuel pricing scenarios, significant renewable energy capacity is deployed.

Solar Photovoltaic Toolkit

This data set compiles capital costs (CAPEX) and levelized cost of energy (LCOE) data for the solar photovoltaic (PV) technology by year and country and presents the data in an interactive manner. Although, the data set contains information that dates back to the 1980s, most of the information covers the past 10 years.

Trends in Global Solar PV Installation

Dozens of governments around the world have supported, and still support, renewable energy technology deployment, including solar photovoltaics (PV). This has been driven by their ambitions to be energy independent, meet carbon emission reduction targets, and contribute to their domestic economies through industry creation.

An Improved Understanding of The Balance of System Costs Can Improve The Economics of Solar PV Projects

Much of the discussion around the cost of solar photovoltaic (PV) generation has focused on the costs of PV modules that convert sunlight to electricity. The overall capital cost of a PV system consists of two components: the cost of the modules and the balance-of-systems (BOS) costs. The BOS is a catch-all term to describe everything needed to erect and commission the PV system. The BOS costs include cables, the mounting system, solar inverters, labor costs, permitting costs, and site preparation costs.
