Finding Opportunity in Economic Dispatch: Saving Fuels Without Impacting Retail Electricity Prices

Finding Opportunity in Economic Dispatch: Saving Fuels Without Impacting Retail Electricity Prices

For important domestic public policy reasons, many oil- and natural-gas-producing countries allocate fuels to their electricity sector at administratively set prices that are below fuel opportunity costs. This article shows that dispatching power units based on fuel opportunity costs can significantly increase efficiency, while, for political reasons, end users’ electricity prices can continue to be defined based on administratively set fuel prices. In addition, opportunity cost dispatch can bring about environmental benefits when it results in switching the priority levels of oil and gas units in the merit order. This work also resolves the electricity trading dilemma since countries do not want to export electricity based on domestic prices.

How Can the European Energy Crisis Reshape the Power Sector Reform Endeavors of GCC Countries?

How Can the European Energy Crisis Reshape the Power Sector Reform Endeavors of GCC Countries?

Energy prices in Europe have been soaring, and policymakers are trying to find solutions to immediately contain the energy prices for end-consumers and to enhance the market design in the longer term. This paper discusses some of the current events that are facing the power sector in Europe and some challenges that may face the industry more generally in the future. Then, we propose policy recommendations in the context of Gulf Cooperation Council (GCC) countries by contrasting the power sector design in place in this region with that in the European region.

How Firm Capacity and Forced Outage Rate Assumptions of Renewables Impact Capacity Expansion Model Results

How Firm Capacity and Forced Outage Rate Assumptions of Renewables Impact Capacity Expansion Model Results

The undergoing energy transition relies heavily on the deployment of renewables such as solar photovoltaic (PV) and wind power for the generation of electricity. These variable and intermittent resources would modify power systems’ reliability compared to the situation where electricity is generated by conventional dispatchable power plants. It is also important to accurately capture their contribution to resource adequacy in long-term expansion planning. This discussion paper assesses how varying the firm capacity (FC) and forced outage rate (FOR) assumptions of renewable energy (RE) impact capacity expansion models (CEM). Eight scenarios that vary the FC and FOR, RE share targets, and annual RE uptake were run on a power system model of Saudi Arabia. Assuming a relatively high FC and a relatively low FOR favors renewables (i.e., Optimistic-RE), while the opposite disfavors them (i.e., Pessimistic-RE). Compared with optimistic RE assumptions, the pessimistic RE assumptions result in significant increases in costs, emissions, and battery storage deployment of up to 11%, 17%, and 41%, respectively. However, no observable patterns were found for resource adequacy. Quantifying the extent to which FC and FOR of RE technologies, which are considered heavily weather-dependent, impact investments in the power sector provides valuable insights for policymakers as the world moves forward more aggressively with RE deployment to reduce emissions and combat climate change.

One Year After the Texas Blackout: Lessons for Reliable and Resilient Power Systems

One Year After the Texas Blackout: Lessons for Reliable and Resilient Power Systems

In February 2021, Texas experienced an extreme cold snap causing a dramatic electricity blackout that left millions of households without electricity, resulting in over 200 fatalities and economic damages of approximately $100 billion. The Texas blackout has been used to support a variety of claims regarding renewable energy, electricity markets and climate change. We identify the blackout’s drivers and what has been learned since then. These lessons apply to power systems worldwide, including those of the Gulf Cooperation Council and the broader Middle East and North Africa region.

Renewables, Reliability and Efficiency in Electricity Markets

Renewables, Reliability and Efficiency in Electricity Markets

The choice to use electricity markets to transition to an ultra-high renewable electricity sector depends on whether a high level of reliability and efficiency can be achieved. This study presents a reliability, resiliency and adaptability policy framework for a liberalized power system with a high share of renewables. This framework provides policy insights regarding electricity market reliability and the implications of remuneration mechanisms for renewables. Our analysis shows that it is necessary to reconsider adequacy assessments of liberalized power systems, to enhance the definition of the loss of load probability, and to explicitly consider the probability that the market clears. Under these conditions, electricity markets can theoretically achieve reliability and efficiency with large percentages of variable and intermittent renewable resources with zero or near-zero marginal costs, and market and technical challenges can be addressed.

A Meta-Analysis of the Long-Term Oil Demand Emerging from the Power Sector

A Meta-Analysis of the Long-Term Oil Demand Emerging from the Power Sector

Oil is a versatile source of energy that is used in various sectors, including the power sector. The power sector is transitioning toward low-carbon generation sources. During this transition, it is important to understand the role of oil-based power generation. This paper presents a meta-analysis of the long-term oil demand emerging from the power sector at the international level and by region. The analysis assesses and compares 19 prospective scenarios published between 2021 and 2023.

Why is the EU Carbon Price at a Record €60 per Tonne?

Why is the EU Carbon Price at a Record €60 per Tonne?

Carbon prices soared above €60/tonne for the first time on August 30, 2021, with the expectation of tightened environmental legislation. These prices made a new record on the European Union Emission Trading System (EU ETS), the European Union’s carbon market. The stressed gas market and expectations of a tighter gas supply in Europe are also behind rising carbon prices. These factors spilled over into electricity prices, which also broke highs, hitting €140 per megawatt hour (MWh) in real-time trading on September 1, 2021.

Why are European Wholesale Electricity Prices Soaring?

Why are European Wholesale Electricity Prices Soaring?

Since the beginning of summer 2021, European wholesale electricity prices have been soaring to historic highs. The average day-ahead price of electricity for central European countries more than doubled between June and September, reaching 170 euros per megawatthour (e/MWh) on September 15. This data insight discusses this unprecedented increase in wholesale electricity prices and their key drivers.

Lessons From the European Electricity Crisis

Lessons From the European Electricity Crisis

On January 23, 2023, the European Commission initiated a public consultation to reform the European Union’s electricity market (European Commission 2023) on the heels of extremely high wholesale electricity prices in Europe in the last months and days of 2022. Negative spot prices, however, were recorded in a large number of European countries on January 1, 2023, including Spain, France, Switzerland, Germany and the United Kingdom. Despite the large variety in how power systems are organized worldwide, from fully integrated monopolies to liberalized systems, all countries can learn from Europe’s experience. In Saudi Arabia and the Gulf Cooperation Council (GCC) countries, liberalization and markets are being introduced progressively, and it is an opportune time to learn from experiences abroad.
