The mini-grid market for private sector is still small in [[Mozambique Off-grid Knowledge Hub|Mozambique]]. [[Policy and Regulatory Framework for Mini/Nano Grids in Mozambique|Regulatory restrictions]] limit the participation of the private sector to develop mini-grid projects. Unlike the market for [[Mozambique Solar Hub|Solar Home Systems (SHS)]]  and [[Mozambique Cooking Energy Hub|Improved Cookstoves (ICS)]], which are targeted at individual users, namely a household or institution, mini-grids provide access to electricity to a larger number of end-users simultaneously.
 There are different solutions for achieving off-grid rural electrification such as stand-alone solutions, nanogrids, mini-grids etc. and are explained in detail below:

 Mini-grids are often cost and technology intensive and there needs to be enough electricity demand from the community to meet the O&M cost of the mini-grid for long-term sustainability. SHS on the other hand, usually meet demands of a single family and the electricity supplied is usually enough for a couple of activities like lighting, phone charging, watching TV, listening to radio etc. Thus, there exists a gap between the demand for electricity, which is not meet by SHS but is too small for a mini-grid to be constructed; this is where nanogrids play a role.

As the energy demand/supply increases, there is also an opportunity for powering productive uses with the swarm grid. The LVDC is usually owned by the community and the electricity generated is traded among the community members.

 ME Solshare is one of the companies which is piloting swarm electrification in rural areas of Bangladesh. The company has built a microgrid with a peer-to-peer trading platform for trading electricity among the users such that SHS users can sell excess electricity to non-SHS users.
