This document legally establishes technical and other requirements for the connection to and use of an electrical utility in a manner that will ensure reliable, efficient, and safe operation.

NRS097-2-3 (2023): This specification clarifies conditions under which small scale embedded generators (<1MW) may connect to distribution feeders without negative network impact, and thus not require impact studies. Application of the specification speeds up connection approvals significantly (NRS Association).

NRS097-2-1 2017 (Ed2.1 revised July 2020): This section of NRS 097 series aims to be technology neutral and focuses on the requirements at the interface between the embedded generator and the utility, although it is expected that the specification will mainly apply to photovoltaic grid connected systems interfaced through static power converter technology. Static power converters are also utilized to convert for example, wind power, micro-hydro power, pico hydro power, battery storage energy and fuel cells to grid compatible electricity.  This specification covers aspects of the Grid Code relevant to small-scale (up to 1MVA) embedded generators, including power quality and safety concerns. (NRS Association)

(SAMPLE) VDE -AR-N 4105 (2011) – Technical minimum requirements for the connection to and parallel operation with low-voltage distribution networks. German standard summarising essential aspects to be taken in to account to ensure safe and reliable network operation.

These are the set of rules which define conditions for accessing the electricity grid.

The guideline is intended to standardise the installation of Rooftop Solar PV in South Africa in the absence on national standards covering such systems.  It explains the basics of electricity generation, Solar PV components, planning and sizing of the Solar PV installation. Other general guidelines are presented on working from heights, recurring duties and appropriate example installations. This therefore presents a detailed overview for everyone who is involved in the planning, installation, operation and maintenance of PV systems. The Solar PV Installation Guidelines are aligned with the National Solar PV Service Technician Qualification and assists the Solar PV installer to use international best practices when installing and maintaining grid-tied Solar PV systems (South African Photovoltaic Industry Association).

Grid codes provide the rules for the power system and energy market operation, ensuring operational stability, security of supply and well-functioning wholesale markets. A set of grid codes can include, for instance, connection codes, operating codes, planning codes, market codes. This report provides guidance to regulators, policy makers, system operators and other stakeholders on how grid connection codes should be developed and implemented. It considers the country context with a view to enabling a higher share of VRE in the power system (IRENA).

The objects and principles of this act are to amend the Electricity Act, Cap. 145. The proposal to amend the Electricity Act, Cap. 145 was intended to remove inconsistencies in the law introduce flexibility in its implementation and to streamline operations of the electricity sector.

(Powerpoint) Provides an overview of the IEEE 1547-2018 Standard.

This standard:

Specifies functional requirements for all Distributed Energy Resources (DERs) connected to typical primary or secondary distribution voltage levels.  It applies regardless of type and size—synchronous, induction, and inverter-based resources of any size.

Gives precedence to synchronous generator design standards for DERs with synchronous generator units rated 10 MVA and greater.

Does not apply to resources directly connected to the bulk power system.

(Note: Superseded by 2018 version) This standard focuses on the technical specifications for, and testing of, the interconnection itself.  It provides requirements relevant to the performance, operation, testing, safety considerations, and maintenance of the interconnection. It includes general requirements, response to abnormal conditions, power quality, islanding, and test specifications and requirements for design, production, installation evaluation, commissioning, and periodic tests. The stated requirements are universally needed for interconnection of distributed resources (DR), including synchronous machines, induction machines, or power inverters/converters and will be sufficient for most installations. The criteria and requirements are applicable to all DR technologies, with aggregate capacity of 10 MVA or less at the point of common coupling, interconnected to electric power systems at typical primary and/or secondary distribution voltages (Institute of Electrical and Electronics Engineers).

Recommendations for the Connection of Type Tested Small-scale Embedded Generators (Up to 16A per Phase) in Parallel with Low-Voltage Distribution Systems.

The purpose of this Engineering Recommendation is to simplify and standardise the technical requirements for connection of Small Scale Embedded Generators (SSEGs) for operation in parallel with a public low-voltage Distribution System, by addressing all technical aspects of the connection process from standards of functionality to site commissioning (Energy Networks Association).

This Regulation (EU 2016/631) establishes a network code which lays down the requirements for grid connection of power-generating facilities of any size, namely synchronous power-generating modules, power park modules and offshore power park modules, to the interconnected system. It, therefore, helps to ensure fair conditions of competition in the internal electricity market, to ensure system security and the integration of renewable electricity sources, and to facilitate Union-wide trade in electricity. (European Commission)

(SAMPLE) This European Standard specifies technical requirements for the protection functions and the operational capabilities of micro-generating plants, designed for operation in parallel with public low voltage distribution networks.

It applies irrespectively of the micro-generating plants’ primary source of energy, where micro-generation refers to equipment with nominal currents up to and including 16 A per phase, single or multi phase 230/400 V or multi phase 230 V (phase-to-phase nominal voltage).

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.

The report is a summarised version of a study which provides an overview of the characteristics of the Indian power system and its problems with regard to a large-scale rooftop PV rollout, as well as a template for distribution companies on how to deal with rising PV shares, which studies to conduct and which technology options to select.

This paper addresses the need to define all important aspects of self-consumption with the focus on commercial issues and avoidance of cross-subsidization among consumer’s groups.  A primary goal of this paper is to recognize all important aspects that need to be regulated to make prosumers concept fully effective in practice. Where possible it provides recommendations that can be used as a good practice for policy makers in the European Union Energy Community countries (ECDSO-E Working Group, EU).

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).

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)

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.

Covering final recommendations for developing the new Model Regulation for Grid-Connected Rooftop Photovoltaic (GRPV) in India after analysing inputs gathered from stakeholder consultation, international review and As-Is assessment of the current regulatory framework in India (World Bank-State Bank of India Grid-Connected Rooftop Photovoltaic Technical Assistance program).

How Energy Ministers can support cheaper, faster decarbonisation via distributed energy resources. Based on the Australian experience, recommendations are provided for unlocking distributed energy resources, including describing the necessary technical and regulatory frameworks (Institute for Energy Economics and Financial Analysis).

The significant decrease of costs of small-scale renewable energy technologies creates new opportunities for electricity consumers to get involved in driving the energy transition. ‘Prosumer’’ refers to an electricity consumer that produces part of his/her electricity needs from his/her own power plant and uses the distribution network to inject excess production and to withdraw electricity when self-production is not sufficient to meet his/her own needs.

The Policy Guidelines summarize the findings and recommendations of the study: “Distributed Generation for Self-Consumption, Key Aspects and Recommendations of Good Practice” prepared under the cooperation platform of Energy Community Distribution System Operators (ECDSO-E), with a focus on recommended practice for small installation of “prosumers” connected to distribution network.
