MEASURES project puts Accra under spotlight for sustainable energy strategy development

A multi-disciplinary group of experts from Ghana and Switzerland are undertaking a study to develop new methods to address gaps in energy system models for developing countries and cities.

Developing countries, like Ghana, grapple with socio-technical and economic factors rarely represented in conventional energy modeling approaches, which are often developed by and for industrialized nations. Such factors include the impacts of the informal economy, suppressed energy demand, power sector failures, and climate change on urban energy resilience and planning. Researchers in this project are working together to represent these issues in energy planning models, and to apply them to the case study city of Accra, supporting its sustainable development.

 

Accra is committed to sustainable urban planning as a signatory city within the C40 Cities and Global Covenant of Mayors for Climate and Energy frameworks. As the focal case study city within this project, the municipality can directly benefit from this work in developing their climate strategy.

However, the outcomes of this study can also help other cities around the world to apply demonstrated models and methods to their own sustainable energy strategy development.

 

The project, titled, “Energy System Modeling for the Real World: Transforming Modeling Approaches for Sustainable and Resilient Urban Development (MEASURES)”, is funded by the Swiss National Science Foundation (SNF) and is running from 2020 until the end of 2023.

 

The project is being led by Dr. Mashael Yazdanie, a research scientist at the Urban Energy Systems Laboratory at Empa in Switzerland. Ghanaian project partners include the Department of Economics and The Brew-Hammond Energy Center at the Kwame Nkrumah University of Science and Technology (KNUST), as well as the University of Energy and Natural Resources (UENR).

 

“One of the interesting things about the MEASURES project is its goal of advancing modeling methods for resilient and sustainable energy planning through international and interdisciplinary collaboration,” said Prof. George Yaw Obeng, Dean of Faculty of Mechanical and Chemical Engineering, KNUST.

 

The first conference and workshop of the Swiss-Ghanaian MEASURES project was held at the KNUST in October 2022. The event brought together researchers, practitioners and experts across a wide range of fields. In addition to the partner institutes (Empa, KNUST and UENR), local attendees included the Accra Metropolitan Assembly, Ministry of Environment Science Technology and Innovation, Environmental Protection Agency, Electricity Company of Ghana, and Digital Earth Africa, amongst others, enabling valuable exchanges and learning opportunities.

 

"This project presents a unique opportunity to collaborate across disciplines, professions, and boundaries in order to collectively tackle one of the most urgent challenges facing humanity – that of mitigating climate change impacts on society and our planet," said Dr. Yazdanie.

 

The importance of energy system models

 

Energy system planning models are vital decision support tools. Developing cities, like Accra, are particularly vulnerable to climate change impacts, such as increased heatwaves, flooding events and rising sea levels, compared to cities in industrialized nations. Thus, maximizing their resilience is essential, and modeling tools can play a pivotal role in evaluating and developing resilient urban energy plans.

 

"Our aim is to improve energy planning models and related decision-making processes in order to support cities and nations in developing more effective sustainable and resilient energy system plans, particularly under the threat of climate change," said Dr. Yazdanie.

 

Multiple experts, including economists, climate change scientists, engineers, and energy system modelers are working together to identify synergies and integration opportunities between modeling methods.

 

“We will build upon existing open-source optimization/simulation models and demonstrate developed methods using Accra as a case study city. We aim to ensure knowledge transfer, especially to urban energy planners, modelers and researchers by sharing models, data, methods, and findings on open-access, digital platforms and through workshops,” said Dr. Yazdanie.

 

The research and knowledge generation on modeling approaches for resilient and sustainable energy planning are relevant to the development of decision-support systems that will help build resilient and sustainable energy planning practices in Ghana and beyond.

The experience of sustainable energy and development in Ghana

Construction permits have been issued to a number of solar investors, with an expected 80-100MWp of solar PV power plant to be completed and connected to the national grid in 18months, the Ghana Energy Commission has stated.

Site permits have also been issued for wind and wave power, whilst provisional licenses have been issued to investors interested in producing power from biomass and wastes, totaling 424MW.

“Installation of the first turbines of 1000MW wave energy farm has commenced at Ada and we expect the first electrons flow from the plant within two months,” said Dr. Alfred Ofosu Ahenkorah, Executive Secretary of the Energy Commission.

Ghana’s local manufacturing sector and industries are collapsing due to the inability of the energy sector to meet their electricity needs.

Dr. Ahenkorah says sustainable energy development means looking at indigenous resources, including renewable energy. These resources include woodfuel – charcoal and firewoods, solar and wind energy.

The use of firewood cookstoves creates jobs for artisans along the cookstoves value chain – producers of liners and fabricators of stoves, distributors and retailers. Woodfuels could also be used as fuel for electricity generation.

“One could cultivate wood plantations, manage existing forest and even forest reserves and use the wastes, dead branches and fruits as fuel for biomass power plants,” stated Dr. Ahenkorah.

He spoke on: “Energy and Sustainable Development: the Ghanaian Experience” at the 2^nd International Economics Conference in Kumasi, organized by the Department of Economics at the Kwame Nkrumah University of Science and Technology (KNUST).

He acknowledged that “improved access to sustainable energy services in Ghana has a great potential to create more jobs, improve lives, reduce the cost of goods, generate revenue for government and stabilize the local currency.”

Sustainable energy development, he noted, rests on the three pillars of environmental and socio-economic integrity as well as energy security, without which there would be no meaningful development.

“The Ghanaian economy is currently unable to supply the needed energy for growth and development. Even though Ghana is endowed with rich and natural sources of energy such as petroleum, river bodies, forest and solar, other factors of production are needed to ensure sustainable use of these natural resources,” said Dr. (Sr.) Eugenia Amporfu, Head of the KNUST Department of Economics. The factors, she said, include labour, human and physical capital as well as entrepreneurial ability.

The Energy Commission is currently reviewing and updating existing policies and plans to steer the country towards the sustainable development, management and utilization of both renewable and nonrenewable energy sources to support economic growth of the country.

 

Dr. (Sr.) Amporfu, has called for partnership from both the public and private sectors to tap into the “rich brains” at the department as they work towards creating a research centre.
