Artificial Intelligence and Smart Technologies in Energy Management: Global Practice and the Emerging Case of Ghana and Africa

Definitions and Scope of AI and Smart Technologies

Artificial intelligence in energy management refers to computational algorithms — especially machine learning and data analytics — that learn from data to optimise energy production, distribution, and consumption. AI techniques, ranging from simple regressions to deep learning and generative models, can forecast demand, detect faults, optimise control, and coordinate distributed energy resources. A smart grid is an electricity network enhanced with digital communication and control, embedding sensors, smart meters, and automation to create two-way flows of data and power. Such grids incorporate emerging technologies including sensor networks, microgrid frameworks, energy storage systems, and distributed renewable generation, alongside the management approaches needed to coordinate them (Balamurugan & Narayanan, 2025).

In practice, this encompasses smart meters, IoT sensors, building and industrial energy management systems, and renewable energy monitoring. AI is often layered on top of this smart infrastructure — for example, ML models running on IoT data — creating smart energy management systems capable of forecasting loads, automating demand response, and self-healing. Modern frameworks increasingly include digital twins, or virtual replicas of the grid, together with advanced AI paradigms such as federated learning and large language models, to enable robust, scalable decision-making (Banad et al., 2025).

This article covers AI-driven methods across electricity generation, transmission, and end-use, together with enabling smart technologies such as IoT. Particular attention is given to smart metering, demand-response programmes, predictive maintenance of grid assets, grid optimisation, and energy efficiency in buildings and industry, with a focus on African contexts and Ghana-specific initiatives. “Smart technologies” is used broadly to include sensors, advanced metering infrastructure (AMI), edge and cloud computing, and optimisation algorithms.

2. Current Applications in Energy Management

2.1 Global Overview
Worldwide, AI and smart technologies are widely applied across modern grids and buildings. Many utilities deploy smart meters with two-way communication to detect theft and enable dynamic pricing (International Trade Administration, 2024). Machine learning supports load forecasting — predicting short- and long-term demand — and renewable integration, using weather and forecast data to optimise solar and wind output. In buildings, AI-driven energy management systems using IoT sensors can control HVAC and lighting, cutting energy use substantially, while in industry, predictive maintenance uses neural networks and related models to anticipate equipment faults.

Okouma et al. (2024) propose a layered IoT-plus-AI smart energy system for cities; simulated results show approximately a 34% improvement in energy efficiency, 30% better reliability, and a 28% cost reduction relative to baseline (Okouma et al., 2024). Broader reviews note that AI in smart grids can help manage renewable intermittency, match supply and demand in real time, and even strengthen cybersecurity (Banad et al., 2025; Balamurugan & Narayanan, 2025)

2.2 Applications in Africa and Ghana

Across Africa, the use of AI and smart technology is emerging. Utilities in Nigeria and Kenya have begun pilot smart-grid projects, and African research on the topic is accelerating. In Ghana, government and partners have launched initiatives including a plan to install roughly one million smart meters — covering about 25% of consumers — under a World Bank programme intended to reduce losses and improve billing (World Bank PAD, 2024; International Trade Administration, 2024).

At the research level, Attakora-Amaniampong et al. (2026) studied an AI-based energy monitoring system in Ghanaian student hostels, using ML-enabled monitors that gave occupants instant feedback. Rooms with AI systems consumed about 8.6 kWh less electricity per month than those without (Attakora-Amaniampong et al., 2026), illustrating how AI can both forecast use and influence consumer behaviour.

Other African studies include Olatunde et al. (2025), who developed an IoT-plus-neural-network predictive maintenance system for Nigerian smart grid components, achieving roughly 95% accuracy in fault detection (Olatunde et al., 2025). In Ghana’s cities, Avordeh et al. (2025) analysed 8,760 hours of load data in Accra and Kumasi to evaluate demand-response interventions, finding that well-designed programmes could reduce peak usage by about 0.406 kWh per event, though poorly structured programmes sometimes raised demand (Avordeh et al., 2025). These results suggest that demand-response and automation can help integrate renewables and shave peaks. Innovative microgrid projects also use AI: a Togolese telecom microgrid was optimised using adaptive fuzzy inference and particle swarm algorithms to supply cell towers and local loads, achieving about 98.9% solar utilisation and near-complete generator inactivity (Dadjiogou et al., 2024) — an approach that could translate to Ghana’s rural off-grid and mini-grid electrification efforts.

In sum, applications across Ghana and Africa span several areas:

• Smart metering and AMI: large-scale smart-meter rollouts planned in Ghana and piloted in Nigeria (International Trade Administration, 2024; World Bank PAD, 2024)

• Demand response and load shifting: AI-forecast-driven programmes to shift consumption (Avordeh et al., 2025)

• Predictive maintenance: ML and IoT sensors predicting failures in generators and transformers, as in Nigeria (Banad et al., 2025)

• Grid optimisation: algorithms balancing generation, transmission, and storage, explored in Kenya and South Africa

• IoT-enabled monitoring: sensor networks such as Accra’s GridWatch project collecting voltage and frequency data for system analytics

• Building and home energy management: AI controlling appliances and providing behavioural feedback, as studied in Ghanaian university housing (Attakora-Amaniampong et al., 2026)

• Renewable integration: AI forecasting solar and wind output to stabilise weak grids, including work supporting Ghana’s 10% renewable-energy target.

These examples show AI and smart technology being tailored to local needs: Okouma et al. emphasise low-cost IoT and layered architectures suited to emerging cities (Okouma et al., 2024), while Ghana’s National Energy Compact highlights geospatial planning and smart-grid telemetry as strategic priorities (World Bank, 2026)

3. Technical Approaches and Algorithms

AI-enabled energy systems employ a range of algorithms and architectures.

• Machine learning and AI techniques — common methods include linear and multilinear regression, time-series models such as ARIMA, ensemble methods (random forests, gradient boosting), and deep learning (neural networks, LSTM), used for load forecasting, anomaly detection, and demand-response. Attakora-Amaniampong et al. used ordinary least-squares regression to link AI feedback installation to lower usage (Attakora-Amaniampong et al., 2026), while Dadjiogou et al. used an adaptive neuro-fuzzy inference system to predict solar irradiance in a microgrid (Dadjiogou et al., 2024). Newer paradigms are emerging too, including federated learning, generative AI and large language models for context-aware planning, and combined AI-plus-IoT (AIoT) frameworks (Banad et al., 2025).

• Optimisation algorithms — heuristic and metaheuristic methods such as particle swarm optimisation, genetic algorithms, and linear programming are common; in the Ghana/Togo microgrid example, particle swarm optimisation identified the best configuration of solar, battery, and diesel capacity to minimise cost and shortages (Dadjiogou et al., 2024). Other studies use mixed-integer programming for hybrid-plant dispatch scheduling or nonlinear optimisation for demand-side bidding, and reinforcement learning is gaining interest for real-time grid control.

• IoT and sensing — a physical layer of smart meters, phasor measurement units, weather sensors, and building meters feeds data to AI systems. Okouma et al. outline a multi-layered architecture — sensing, communication, processing, and application — through which IoT devices feed ML models (Okouma et al., 2024).

• Edge and cloud computing — connectivity across much of Africa is limited, making edge computing, or local data processing, especially important. Rural deployments often process data partially on-site, such as anomaly detection at the meter, before sending summaries to the cloud (Energy Catalyst UKRI, 2023); Okouma et al. describe algorithms that run partly on edge devices and partly in the cloud for real-time control (Okouma et al., 2024).

• Digital twins and simulation — advanced projects use real-time virtual replicas of the grid to test scenarios for planning and resilience (Banad et al., 2025); while still nascent in Africa, the concept is being piloted in some smart-city research.

• Communication and standards — interoperability via standards such as IEC 61850, together with secure communication protocols, forms an essential part of the technical solution.

In summary, AI-driven energy management typically combines data-driven modelling with optimisation algorithms, running on distributed IoT-plus-edge/cloud infrastructure. The choice of method depends on the task: forecasting and pattern recognition rely on ML and deep learning, while operational scheduling relies on optimisation. Ghana’s National Energy Compact specifically calls for utility digitalisation — including meter data management and SCADA/DERMS systems — alongside strong cybersecurity and privacy frameworks (World Bank, 2026)

4. Benefits and Measured Outcomes

• Energy savings and efficiency — AI-based monitoring cut electricity use by about 8.6 kWh per room-month in Ghanaian student housing (Attakora-Amaniampong et al., 2026); Okouma et al. simulated a 34% improvement in overall energy efficiency from an IoT-plus-AI system (Okouma et al., 2024); and Ghana’s demand-response study found even modest behavioural shifts reduced usage by about 0.4 kWh per event (Avordeh et al., 2025).

• Peak reduction and demand flexibility — by forecasting demand and controlling devices, smart systems can shave peaks; Avordeh et al. found that well-designed demand-response programmes in Accra and Kumasi yield significant load reductions (Avordeh et al., 2025), helping integrate more renewable energy.

• Reliability and outages — AI and ML provide effective tools for managing renewable intermittency, dynamic demand, and cybersecurity (Banad et al., 2025), directly enhancing grid stability; AI in smart grids can decrease the risk of power outages and brownouts (Balamurugan & Narayanan, 2025). Smart sensors and ML can also detect faults early, as in Olatunde et al.’s predictive-maintenance work at 95% fault-detection accuracy (Olatunde et al., 2025).

• Cost reduction — Okouma et al. estimate about a 28% cost reduction from their AI-optimised system (Okouma et al., 2024); Dadjiogou et al. achieved a cost of just 0.0185 USD/kWh for a PV-battery rural electrification system optimised by AI, far cheaper than diesel generation (Dadjiogou et al., 2024).

Smart-metering programmes also reduce commercial losses, with Ghana’s rollout aiming to recoup significant unpaid revenue.

• Security and sustainability — AI can flag tampering or inefficiency in real time and, by enabling higher penetration of solar and wind, helps decarbonise generation by matching renewable output to demand and reducing reliance on diesel backup. In buildings, smarter controls cut waste by changing occupant habits, not only forecasting use (Attakora-Amaniampong et al., 2026).

Taken together, published metrics point to consistent gains: reported improvements include roughly 34% energy-efficiency gains, 32% predictive-demand accuracy, 30% system reliability, and 28% cost reduction in one integrated IoT-plus-AI deployment (Okouma et al., 2024). These figures, alongside the case examples above, demonstrate that AI and smart technology can deliver on the promise of energy savings, peak shaving, and improved service quality in Ghana and beyond.

5. Barriers and Challenges in Ghana and Africa

• Infrastructure limitations — many African grids are ageing and lack real-time monitoring; roughly half of ECG’s customers in Ghana still use prepaid meters over 15 years old with no digital link to billing systems (World Bank PAD, 2024), and ICT backends are weak. Reliable internet or 5G coverage is spotty outside cities, complicating IoT deployment.

• Data scarcity and quality — AI depends on data, but accurate load and usage data are often missing; rural planners frequently lack accurate, location-specific data on demand patterns, consumption behaviour, and settlement distribution, turning planning into guesswork (Energy Catalyst UKRI, 2023). This constrains ML training and limits predictive-model effectiveness, making new local datasets, such as Ghana’s Accra grid-sensor project, an urgent need.

• Financial constraints — upfront costs for smart meters, sensors, and AI systems can be prohibitive; Ghana’s smart-meter programme relies on World Bank financing, reflecting the need for public or donor support, while African energy developers often lack the collateral or reliable revenue data needed to attract private investment (Energy Catalyst UKRI, 2023).

• Regulatory and institutional gaps — policy frameworks are often undeveloped; Ghana had no formal digital-grid transformation strategy until its 2026 Energy Compact (World Bank, 2026), and regulations for data privacy, cybersecurity, and interoperability remain nascent. Utility fragmentation and unclear mandates slow unified action, with institutional inertia identified as a limiting factor for adoption (Acakpovi et al., 2019).

• Skills and knowledge — a shortage of local expertise in AI, data analytics, and digital power systems means utilities and governments need more engineers and data scientists trained in these fields, which will take time and resources to build.

• Interoperability and compatibility — integrating new AI and IoT tools with legacy grid equipment is technically complex; standards such as IEC 61850 exist, but older devices may not comply, adding system complexity and cost.

• Cybersecurity and privacy — as grids digitalise, they become more vulnerable to cyberattack; IoT devices and AI models open new attack surfaces, and African utilities generally have limited experience securing them.

These barriers appear consistently across the literature and industry reviews. World Bank analysts note that ECG’s backlog of old meters and limited ICT lead to poor collection efficiency (World Bank PAD, 2024), while the Energy Catalyst review emphasises that AI implementations in Africa must contend with harsh environments, unreliable networks, and dispersed customers (Energy Catalyst UKRI, 2023). Overcoming these challenges will require concerted investment in infrastructure alongside enabling policy.

6. Policy, Regulatory, and Institutional Recommendations

• National digital energy strategy — Ghana’s National Energy Compact (2026) offers a model by explicitly integrating smart grids and AMI/IoT across its interventions (World Bank, 2026); other governments should adopt similarly strategic plans mapping smart-meter rollouts, grid automation, and AI pilots against clear timelines, with ECOWAS and African Union guidelines encouraging harmonised standards.

• Regulatory frameworks — regulators should set standards for data interoperability and grid communications, for example through licensing conditions mandating digital metering and open data sharing. The Energy Compact’s proposals for machine-readable regulatory workflows and real-time reporting (World Bank, 2026) could be translated into binding regulation, alongside privacy-by-design principles and mandatory utility cybersecurity plans.

• Incentives and funding mechanisms — governments and donors should provide targeted grants or soft loans for smart meters, sensors, and AI systems, following the model of Ghana’s World Bank-financed programme, with subsidies or tax incentives to spur uptake and public-private partnerships to mobilise expertise and capital.

• Capacity building — regulatory bodies and utilities should invest in training staff in data analytics and AI, with universities and technical institutes developing programmes in energy informatics and IoT; Ghana’s Energy Compact already includes capacity-building and gender-diversity goals that donors and agencies can support through technical training and curriculum development (World Bank, 2026).

• Pilot projects and data sharing — policymakers should fund pilot deployments such as microgrid automation and demand-response trials, and support open-data initiatives like Accra’s GridWatch dataset to accelerate research, sharing outcomes from both successes and failures to inform scale-up.

• Institutional coordination — closer collaboration between energy and ICT ministries, regulators, utilities, research institutions, and industry is needed, for example through an Energy Data Agency that centralises grid and consumption data for AI analysis, with telecom regulators aligned to ensure adequate connectivity.

In summary, Ghana and other African governments should adopt comprehensive digitalisation roadmaps for the energy sector, embedding AI and IoT as core pillars alongside supportive data governance and market rules. International experience shows that regulation and stakeholder coordination matter as much as the underlying technology itself (World Bank, 2026; International Trade Administration, 2024)

7. Research Gaps and Future Directions

• African context data and studies — most existing work is conceptual or pilot-scale; new datasets such as Ghana’s Accra GridWatch project should be leveraged for further research, and more field trials of AI control systems within Ghana’s actual distribution network or microgrids are needed to quantify real-world benefits and risks.

• Scalability and interoperability — standardised digital-twin frameworks and federated-learning paradigms are still needed (Banad et al., 2025); African research should prioritise scalable, low-cost architectures suited to low-bandwidth conditions, including algorithms that work with minimal or low-resolution sensor data.

• Localisation of AI — cultural and behavioural factors shape energy use; while studies such as Attakora-Amaniampong et al. show AI can alter habits (Attakora-Amaniampong et al., 2026), more socio-technical research is needed on combining AI with behaviour-change incentives and on social acceptance of smart meters in Ghana.

• Cybersecurity and trust — little work has examined the cybersecurity implications of deploying IoT and AI in Ghanaian power systems; research is needed on securing low-cost sensors, detecting cyberattacks in weak-grid contexts, and protecting consumer privacy.

• Cost-benefit analysis — detailed techno-economic studies remain scarce; future work should quantify the full return on investment of AI systems, including reduced outage costs and environmental benefits, evaluated at whole-system scale.

• Policy and institutional studies — research is needed on regulatory models for smart grids in Africa, including tariff reforms that fund grid upgrades and business models for utilities adopting AI, together with institutional studies of how utilities can organisationally shift toward data-driven operations.

• Advanced technologies in African grids — frontier approaches such as large language models for grid management or blockchain-enabled energy trading remain largely unexplored in the African literature and represent an open research area, particularly where they intersect with off-grid reliability and local renewables.

Future research should move from theory to practice: prototyping and rigorously evaluating AI- and IoT-based energy solutions in Ghana through interdisciplinary work spanning engineering, economics, and social science. Issues of data privacy and algorithmic robustness remain open (Banad et al., 2025) and are especially salient in contexts with limited safeguards; addressing these gaps will help unlock the full potential of AI for Africa’s energy transition.

8. Conclusion
AI and smart technologies are already delivering measurable efficiency, reliability, and cost benefits in energy systems worldwide, and early evidence from Ghana and Africa — from student-housing monitoring to demand-response trials and rural microgrids — suggests these gains are transferable to African contexts. Realising that potential at scale will depend less on the technology itself than on addressing the infrastructure, data, financing, skills, and regulatory gaps that currently constrain adoption. Ghana’s National Energy Compact marks a significant step toward a coordinated digitalisation agenda; sustaining that momentum will require continued investment, capacity building, and rigorous, locally grounded research.
