The supply of electricity is growing increasingly dependent on the weather as the share of renewable energies increases. Different measures can nevertheless maintain grid reliability and quality. These include the use of storage technologies, upgrades of the grid and options for responsiveness to supply and demand. This paper focuses on demand side management and the use of flexibility in production processes. First, the framework of Germany’s energy policy is presented and direct and indirect incentives for businesses to seek as well as to provide flexibility capabilities are highlighted. Converting this framework into a mixed integer program leads to multi-objective optimization. The challenge inherent to this method is realistically mapping the different objectives that affect business practices directly and indirectly in a variety of laws. An example is introduced to demonstrate the complexity of the model and examine the energy flexibility. Second, manufacturing companies’ energy efficiency is assessed under the frequently occurring conditions of heavily aggregated energy consumption data and of information with insufficient depth of detail to perform certain analyses, formulate actions or optimize processes. The findings obtained from the energy assessment and energy consumption projections are used to model the production system’s energy efficiency and thus facilitate optimization. Methods of data mining and machine learning are employed to project energy consumption. Aggregated energy consumption data and different production and environmental parameters are used to assess indirectly measured consumers and link projections of energy consumption with the production schedule.

With the ever-growing power demand, the energy efficiency in commercial and residential buildings is a matter of great concern. Also, strategic energy auditing (SEA) and demand-side management (DSM) are cost-effective means to identify the requirements of power components and their operation in the energy management system. In a commercial or residential building, the major components are light sources and heating, ventilation, and air conditioning. The number of these components to be installed depends upon the technical and environmental standards. In this scenario, energy auditing (EA) allows identifying the methods, scope, and time for energy management, and it helps the costumers to manage their energy consumption wisely to reduce electricity bills. In the literature, most of the traditional strategies employed specific system techniques and algorithms, whereas, in recent years, load shifting-based DSM techniques were used under different operating scenarios. Considering these facts, the energy data in a year were collected under three different seasonal changes, i.e., severe cold, moderate, and severe heat for the variation in load demand under different environmental conditions. In this work, the energy data under three conditions were averaged, and the DSM schemes were developed for the operation of power components before energy auditing and after energy auditing. Moreover, the performance of the proposed DSM techniques was compared with the practical results in both scenarios, and, from the results, it was observed that the energy consumption reduced significantly in the proposed DSM approach.

Energy-efficiency projects were expected to consti-tute an important project type under the Clean Development Mechanism (CDM). In South Africa, there is significant potential for energy savings in several sectors. The savings possible in industry have been demonstrated through plant-level energy audits, measurement and verification of Eskom’s Demand Side Management (DSM) programme and national energy modelling. Enabling policy for energy efficiency and demand-side management has been adopted by government and the utility, Eskom. A dedicated National Energy Efficiency Agency (NEEA) was established in 2006. Yet, energy-efficiency still fails to realise its potential. The paper seeks to dispel the misconception that energy efficiency projects might not be ‘additional’ under the CDM. Analysis of barriers, which is well understood by those dealing with energy efficiency, can be used to demonstrate additionality. A stan-dard tool for demonstrating additionality is now available, as are baseline methodologies for both large and small-scale CDM projects. It should, therefore, be clear that energy efficiency projects are not a priori ruled out as non-additional. Each proj-ect has to demonstrate additionality, as for any other project type. Finances are available from various sources, and the CDM can offer further funding for initial costs, or in removing the barriers to energy-efficiency projects. Internationally, energy efficiency initially did not account for large numbers of CDM projects, nor a major share of carbon credits. With the recent growth in CDM projects, however, the numbers of energy-efficiency projects are increasing internation-ally. In South Africa, analysis of the emerging CDM portfolio shows that energy-efficiency projects are much better represented at the concept stage than in fully designed CDM projects.The major elements for implementing energy-efficiency projects exist – dedicated institutions, enabling policy frameworks, approved methodolo-gies and even an electricity crisis to raise awareness. Funding is available from various sources, and the CDM can offer further funding for initial costs or in removing the barriers to energy-efficiency projects. The CDM rules should soon allow for registration of entire programmes, which could include energy-efficiency standards or demand-side management. Innovative financing solutions such as clean energy lending can assist as well. All that seems to be needed is a concerted effort to realise the potential. Such efforts could be driven by the Designated National Authority or the National Energy Efficiency Agency. Together with initiatives from the private sector, a dedicated effort might help South Africa find a clear route for ener-gy-efficiency projects under the CDM in South Africa.
