- Power Electronics consolidates its leadership in Spain joining in 82 pv projects.
- The Power Electronics Freesun HEMK solar inverter is the most requested equipment.
- The Power Electronics' products meet all network quality requirements, pending the publication of product certification entities by ENAC.
Power Electronics exceeds 2.5 GW of installed power in utility scale photovoltaic plants in Spain in 2019. In total, the company has participated in 82 PV projects in Spain. Just in the last year, Power Electronics has participated in 36 projects, which makes the company a leader in sales in this market.
Among the major projects of which the company has been part of in the last year is the first photovoltaic macro project of the Iberdrola group in Spain, the Núñez de Balboa solar plant, which, with 500 MWp capacity installed, it will provide clean energy to 250,000 people.
In addition, the company maintains its leadership in North America and Latin America according to the latest report published by Wood Mackenzie Power & Renewables that shows the market share of each of the manufacturing companies.
Among the most demanded equipment in the national scope is the HEMK, a modular solar inverter that offers the advantages of both central and string inverters, with an output power of up to 3.8MW and available in six AC voltages. It is precisely its structure composed of FRUs (field replaceable unit) that makes it the best solution for those customers looking for availability and production optimization.
Power Electronics inverters comply with the technical requirements included in the proposal of Operating Procedure 12.2 – October 2018 version, pending approval by the Ministry.
In July 2019, the first version of the Technical Supervision Standard (NTS) was published, which establishes the procedure for evaluating the requirements for connecting generators to the grid. The NTS v1.0 has been developed to be consistent with the current national regulation proposal.
ENAC and the certification entities
The accreditation of ENAC (National Accreditation Entity) is one of the requirements contemplated by the Technical Supervisory Standard published by Red Eléctrica de España (REE) and the distribution network managers.
This standard allows the conformity of the electricity generation modules to be evaluated in accordance with regulation (EU) 2016/631, which establishes the minimum technical requirements regarding the quality of energy that the new facilities must meet in order to guarantee the European electricity system’s safety, the integration of renewables and facilitate the trade of electricity in the EU.
With this standard, the evaluation of grid connection requirements for generators is harmonized in Spain and the agents that must intervene in the evaluation of these requirements are clearly established, including conformity assessors for that accreditation that mus be required by ENAC or equivalent.
ENAC has developed the accreditation scheme and is able to accredit both laboratories that develop tests and simulations on components, as well as product certification entities that certify components and plants.
In this regard, Red Eléctrica de España, has published a document to correct errors and clarifications to the Technical Supervision Standard, which states that, in the case of entities established in the EU, the only acceptable accreditation will be issued by the National Accreditation Body of the country in which the entity is established.
About the third-party certification announcement
Power Electronics recalls that, according to the information transferred by ENAC, there are currently no certifiers or accredited laboratories.
In that sense, both certifiers and laboratories can begin to be accredited for the NTS, although the certificates issued at this time, not being approved the regulation regarding the grid code, are not valid.
In conclusion, at this time no manufacturer can guarantee the certification or the passing of the normative tests contained in the Technical Supervision Standard.
