Distributed Generation Information Resources

This Regulatory Guidebook offers practical guidance to adapt regulatory frameworks so that they maximize the benefits to society of growing use of distributed energy (DE), and to allow regulatory reforms to be realistically implemented in Africa.

Explores Embedded Generation (or Distributed Generation) tariffs amongst different municipal electricity distributors and the impact on utility revenue. Principles to ensure cost recovery/revenue neutrality are covered, ephasizing the importance of moving from purely volumetric tariffs for DGfixed charges to recover fixed costs. revenue impact amongst different distributors is illustrated graphically (Sustainable Energy Africa, AMEU Convention)

Electricity Net Metering Rules for Tanzania (Govt of Tanzania)

This report is the first in a series called “From Sun to Roof to Grid” dealing with distributed photovoltaics.  It targets policy makers, regulators and utilities—and provides a menu of ideas, approaches, and examples to resolve challenges to the deployment of DG and realize the benefits it can bring (World Bank Energy Sector Management Assistance Program – ESMAP).

This short report defines compensation mechanisms for grid connected, behind-the-meter distributed generation (DG) systems as instruments that comprise three core elements: (1) metering & billing arrangements, (2) sell rate design, and (3) retail rate design. This report describes metering & billing arrangements, with some limited discussion of sell rate design. We detail the three possible arrangements for metering & billing of DG: net energy metering (NEM); buy all, sell all; and net billing.

This study covers the “net metering” mechanism in which a self-generating customer can inject the surplus into the grid and receive compensation for each kWh injected. From data collection done in a selection of countries and literature review, an inventory of best practices is presented. (International Energy Agency Photovoltaic Power Programme).
