Demand Side Management
| DSM encompasses “systematic utility and government activities designed to change the amount and/or timing of the customer’s use of electricity” for the collective benefit of the society, the utility and its customers. As such, it is an umbrella term that includes several different load shape objectives, including load management (LM), energy efficiency (EE) and electrification. |
| DSM Objectives |
| DSM objectives are normally categorised into Corporate, Load Shape and Non-Load Shape objectives and are described below. |
| Corporate Objectives |
| In order for the CEB to achieve its Mission it has set operational and management objectives. This would include improving power quality and reliability, minimizing pilferage, reducing system losses, improving the distribution network, upgrading sub-stations, high collection efficiency, improving customer service etc. |
| Load Shape Objectives |
| Inevitably, as DSM is being considered primarily as a cost-effective alternative to supply-side options, the extent to which a given DSM program meets the CEB’s load shape objectives is of paramount consideration. Like supply-side options, DSM options generally primarily address one of the following specific load shape objectives |
| peak clipping | the reduction of utility load primarily during periods of peak demand |
| valley-filling | the improvement of system load factor by building load in off-peak periods |
| load shifting | the reduction of utility loads during periods of peak demand, while at the same time building load in |
| off-peak periods. Load shifting typically does not substantially alter total electricity sales. | |
| conservation | the reduction of utility loads, more or less equally, during all or most hours of the day |
| load building | the increase of utility loads, more or less equally, during all or most hours of the day |
| provision of a more | |
| flexible utility load shape | refers to programs that set up utility options to alter customer energy consumption on an as-needed basis,as in interruptible / curtailable agreements |
