Walid works on modeling energy systems. He is developing or has developed the following components of the KAPSARC Energy Model (KEM): electric power generation, oil refining, petrochemicals and fertilizers, cement production, and iron and steel. He is also working on a bottom-up residential electricity use framework that merges microeconomics with the physical laws governing electricity use.

On the Incremental Investment in Residential Energy Efficiency: A Saudi PerspectiveThis 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 mo...

Residential Energy Efficiency Investment and Behavioural Response Under Different Electricity Pricing Schemes: A Physical-microeconomic ApproachThe 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 of e...

A Household’s Power Load Response to a Change in the Electricity Pricing Scheme: An Expanded Microeconomic-physical ApproachEnergy economists are interested in how changes in electricity prices prompt a response in end-user electricity demand. If historical prices are low or seldom change, it becomes difficult to estimate price elasticities statistically , especially in the short-run. Thus, a framework th...

Households’ response to changes in electricity pricing schemes: Bridging microeconomic and engineering principlesThis paper presents a computational take on households’ response to price changes. Many studies use assumptions (i.e., price elasticities) that were estimated using historical information; however, if a price change has not been experienced in the past, the response may not be ...

Electricity transmission formulations in multi-sector national planning models: An illustration using the KAPSARC energy modelThe purpose of this study is to assess the 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 availabl...

Striking a balance between profit and carbon dioxide emissions in the Saudi cement industryCement manufacturing is a major industry in Saudi Arabia. As a highly polluting sector, it may be part of CO2 abatement policy for the country. This paper presents a multi-criteria analysis to examine how two competing objectives affect the performance of the cement industry in Saudi...

A look at the response of households to time-of-use electricity pricing in Saudi Arabia and its impact on the wider economyHouseholds in Saudi Arabia account for about half of domestic electricity demand. This high level of consumption is partly due to historically low prices. These prices have also been flat throughout the day. Policymakers are exploring different pricing policies to help reduce this sh...

Jointly reforming the prices of industrial fuels and residential electricity in Saudi ArabiaThe Saudi electricity sector currently buys fuel and sells electricity at prices administered by the government. In this analysis, we illustratively explore combining the reform of the fuel prices used in power plants with the implementation of alternative electricity pricing schemes...

Efficient industrial energy use: The first step in transitioning Saudi Arabia’s energy mixIn Saudi Arabia, industrial fuel prices are administered below international prices and firms make decisions based on low energy prices, increasing domestic energy demand. This analysis explores alternative policies designed to induce a transition to a more efficient energy system by...

The prospects for coal-fired power generation in Saudi ArabiaAlmost all of Saudi Arabia’s electric power generation is fueled by oil and gas. Plans for future capacity envisage nuclear and renewables supplementing this mix and thereby freeing up oil for other revenue-generating opportunities. Coal-fired generation has been promoted in so...

Beyond the end-consumer: how would improvements in residential energy efficiency affect the power sector in Saudi Arabia?Energy efficiency in buildings has garnered significant attention in Saudi Arabia. This paper outlines the potential effects of higher residential efficiency on electricity load profiles in the Kingdom. It further presents the associated benefits that could have been realized by the ...

Lowering Saudi Arabia’s fuel consumption and energy system costs without increasing end consumer pricesUsing a multi-sector equilibrium model of the Saudi energy system that handles administered prices in a mixed-complementarity formulation, we present results from a set of policy scenarios that lower oil consumption in the country. Some of these scenarios are the solutions to Mathema...

The impact of oil price volatility on welfare in the kingdom of saudi arabia: Implications for public investment decision-makingSince real oil price is positively correlated with real consumption and domesticincome in Saudi Arabia, a risk premium needs to be considered when assessingthe net present value of oil-related public investment projects. For projects generatingadditional oil exports, this risk premiu...
