Governance frameworks also play a central role in building regulatory trust and thus influence investments within and into national electricity sectors. Experience shows that electricity systems need to be steered, and that improvements in industry performance and consumption habits (energy efficiency) are incentivized by policy and regulation. While energy-security issues vary widely across national contexts, the primary goal of adequate supply with maximum reliability and quality is universal. The approach to the development of national electricity frameworks appears in some cases to be ad hoc, or in response to donor initiatives, rather than systemic.
