Web-Based User Interfaces for Mathematical Models to Support Decisions: The Fuel Distribution Network Optimizer

Nourah Al Hosain, Jaidaa Alidrisi, Amr Alruthai, Walid Matar, Abdelrahman Muhsen, Pavithra Kumar Shetty, Lama Yaseen, Abeer AlGhamdi

Mathematical models provide quantitative analyses that can inform policy decisions. We argue that two attributes can support models’ adoption by policymakers: an intuitive graphical interface and active engagement between modelers and policymakers.

An Exposition of Bilinear “Implicit” Subsidy Equations

Walid Matar

The price-gap method is popularly applied to estimate energy subsidies, and it simply involves calculating the difference between the market and domestic prices of a good multiplied by the quantity consumed. In the case where subsidies impose foregone revenue rather…

Using Satellite Technology to Measure Greenhouse Gas Emissions in Saudi Arabia

Anwar Gasim, Walid Matar, Abdelrahman Muhsen

Measuring and monitoring greenhouse gas (GHG) emissions are crucial to address climate change and fulfill Paris Agreement objectives. This paper explores the potential of satellite technology in measuring and tracking CH4, CO2, and N2O emissions in Saudi Arabia, collaborating with…

Energy Policy Pathways to Inform Climate Policy in Saudi Arabia

Walid Matar, Noura Mansouri, Evar Umeozor

Saudi Arabia has announced plans to cut greenhouse gas (GHG) emissions by 278 million tons of CO2 equivalent (CO2e). In this regard, this paper contributes a modeling view of the climate-related effects of various energy policies on the Saudi energy…

A Decomposition Approach to Energy Policy Analysis

Walid Matar

Index decomposition analysis (IDA) has been used to study energy use movements since the 1980s. Methods at that time consisted primarily of multiplying factors that ultimately yielded the aggregate quantity, such as energy use. IDA is a straightforward way for…

Modeling the Distribution and Transshipment of Refined Oil Products

Walid Matar

KAPSARC has developed an optimization model to characterize the distribution of oil products after the refining stage. The model ensures that the demand for any group of refined oil products is simultaneously met while minimizing the social costs associated with…

Real Gross Domestic Income for Saudi Arabia From 1986 to 2021

Walid Matar

A country’s national income is defined as the total market value of its output. The most used measure for national income is gross domestic product (GDP). One way to estimate GDP for a country is to sum its government consumption,…

Alternative Fuels for Saudi Cement Manufacturing with Time-varying Carbon Pricing

Walid Matar, Doaa Filali

After cement production in Saudi Arabia surged in the first half of the 2010s due to the country’s rapid economic development, it has slowed measurably in recent years as economic growth has declined. This is shown in Figure 1, along…

Long-run Effects of Real-time Electricity Pricing in the Saudi Power Sector

Walid Matar

This study explores the potential effects of real-time electricity pricing on the operations of Saudi Arabia’s power generation sector. The Kingdom currently sets fuel prices for power utilities at levels that suppress the costs of power generation. However, this analysis…

On the Incremental Investment in Residential Energy Efficiency: A Saudi Perspective

Taylor & Francis Online

This paper examines the marginal welfare gain of adopting higher energy efficiency after another efficiency measure has already been installed. For example, how does installing stringent thermal insulation influence energy efficiency investment decisions thereafter? A mathematical model that embeds a…

Can Oil Refiners Adjust to a Greater Supply of Shale Oil?

Walid Matar, Rami Shabaneh

The advent of American shale oil and its prospects for continued production growth have raised concerns about whether oil refineries can handle the increasingly lighter crude oil supply. To provide a perspective on this issue, we run a global oil…

On the Incremental Investment in Residential Energy Efficiency: A Saudi Perspective

Walid Matar

It has been shown in the literature that, in aggregate, actual household energy efficiency adoption is less than would be expected economically. Energy economists and policy analysts have described this phenomenon as the ‘energy efficiency gap.’ There could be myriad…

Residential Energy Efficiency Investment and Behavioural Response Under Different Electricity Pricing Schemes: A Physical-microeconomic Approach

Taylor & Francis Online

The purpose of this paper is to analyze the effects of electricity price changes and energy efficiency subsidy on household energy efficiency purchase and/or behavioural adjustment decisions. The analysis adds energy efficiency investment to a methodology that merges the physics…

A Look Back on Saudi Fossil Fuel Incentives in the Last Decade

Walid Matar

The Joint Organisations Data Initiative (JODI) and the Saudi Electricity Company (SEC) have just released energy use data for 2019. This insight provides an up-to-date estimation of how fossil fuel incentives have changed in 2019 compared with 2009.
