Recent market liberalization and energy sector reform in Mexico is pushing forward a wave of new potential for DG. This report explores how DG can fulfill many of Mexico’s energy goals. It presents specific policy options to better integrate DG as a cost-effective source of energy generation. Although specifically tailored to Mexico, many of the report’s recommendations can be applied in developing contexts.

To enable informed decision-making and planning related to increasing levels of DPV, the Distributed Generation Interconnection Collaborative (DGIC) facilitates knowledge sharing among its members about DPV interconnection practices, research, and replicable innovations. While the Collaborative primarily works with utilities and other stakeholders in the United States, its website hosts a collection of presentations, webinars, and reports that provide more broadly applicable information and case studies on interconnection practices.

The 21st Century Power Partnership supports global power sector transformation. The Partnership has developed a curated, annotated resource library that provides reports, academic literature, case studies, and good practices to support DG regulation in a variety of power system contexts. The library is organized around several topical areas: ratemaking, understanding impacts, interconnection, alternative business and regulatory models, planning, and case studies.

As part of the U.S. SunShot Initiative—aiming to make PV electricity cost-competitive with conventional generation by 2020—this report analyzes the impact of high-penetration variable generation on the distribution grid, it demonstrates that in most cases DG can be safely integrated at much higher levels than interconnection standards allow. By streamlining interconnection processes, deploying advanced inverter functionalities, and coordinating DGPV, upwards of 350 GW can be hosted on the U.S. grid with little additional hardware. The report also outlines challenges to interconnection such as voltage regulation, power flow, and protection issues. It then studies the role of storage and complementary technologies to overcome reliability constraints. This research is applicable outside of the U.S. in demonstrating how to maximize an existing grid for DG.

IEEE 1547 was introduced in 2003 when DER penetration was low in most places. As some regions like Germany, California, and Hawaii reach higher levels of DG penetrations, alterations to IEEE 1547 are required. IEEE has fast-tracked the development of a full-revision of 1547 to maintain cross-system compatibility; drafts of the new version enhance the capabilities of DER to provide grid support, voltage ride-through, and reactive power modes for generators in high-penetration contexts. The updated version is currently an active draft, the full version will be released in 2018. 1547.1 provides engineers with interconnection system testing guidelines and will also be updated. Both 1547 and 1547.1 are recognized by UL 1741 and are to be used in conjunction.

Traditional interconnection processes evaluate the impacts a distributed generator has on system safety, reliability, and power quality. This concept paper introduces “Integrated Distribution Planning,” an emerging alternative methodology designed to enable DPV. In the report, utilities and distribution system operators proactively study the hosting capacity of distribution circuits, the ability of these circuits to accommodate growth in DG, and any necessary infrastructure upgrades; all in advance of receiving interconnection requests from generators.

Traditional interconnection processes evaluate the impacts of a given distributed generator to safety, reliability, and power quality after an interconnection request is received. This concept note introduces “Integrated Distribution Planning,” an alternative, emerging methodology designed to enable distributed PV. In the Integrated Distributed Planning concept, utilities or distribution system operators proactively study the hosting capacity of distribution circuits, the ability of these distribution circuits to accommodate growth in distributed generation, and any necessary infrastructure upgrades, all in advance of receiving interconnection requests from generators.

Because of Jamaica’s high retail electricity prices, significant opportunity exists for DPV as an economic alternative. This paper reviews the effectiveness of Jamaica’s net billing pilot program, and identifies remaining challenges including a complex interconnection process, contractual ambiguity, and stakeholder equity concerns. The report provides several specific recommendations like shortening interconnection timelines, reducing caps on individual systems, and moving beyond a pilot phase. Many of these recommendations are applicable to other countries, particularly those with similarly high electricity rates.
