Overview

GNERA Energía y Tecnología, S.L. is a Spanish energy services company founded in 2005 and headquartered in Madrid, with a second Spanish office in Getxo (Bizkaia) and an office in Rome, Italy. It operates as an independent market representative (agente representante) in the Spanish electricity market, acting on behalf of renewable energy producers. Its core business is the management and optimisation of electricity sales for renewable generators, together with a broader set of energy-market services. The company describes itself as having operated in electricity markets for around two decades and positions itself among the leading market representatives in Spain. Its service portfolio includes market representation, a control centre and telemetry service built on an in-house measurement concentrator that collects production data from every plant in its representation portfolio, adjustment and balancing markets (secondary and tertiary regulation and Replacement Reserve), price hedging and PPAs including swaps and option valuation, management and transfer of Guarantees of Origin (GdOs), and energy advisory and regulatory notifications for producers. GNERA's stated mission is to collect, organise and interpret energy information and make it available to users in order to improve generation and consumption operations. Its vision links the integration of renewable resources into electricity networks with the fusion of energy sources and information sources. The company frames its activity around three pillars: supporting the evolution of the electricity market and grid by operating and monitoring generation plants, implementing and adapting new technologies to the functional requirements of energy companies, and research and innovation. Its client base is renewable energy producers, and its portfolio of installations is described as geographically and technologically diversified, which the company says helps it achieve good levels of hedging against deviation costs. The company markets itself under the slogan "Our future is green" and presents climate change as the central challenge its business addresses. It is a private limited company (S.L.) and, as of the available evidence, is not listed on a stock exchange.

History

GNERA Energía y Tecnología was founded in 2005, according to the company's own account, with the purpose of participating in the transition towards a new energy model. Its stated mission from the outset was to integrate new energy sources and technology using efficient resources to achieve sustainable and lasting development. The company frames this in the context of climate change as the major challenge facing humanity and of clean, emission-free energy as the key response. Over roughly two decades the company built its business around acting as a market representative for renewable energy producers in the Spanish electricity market. Its own website states that after 20 years operating in electricity markets, GNERA Energía positions itself among the principal representative agents in Spain. This period corresponds to the rapid growth of renewable generation in Spain and the increasing complexity of electricity market rules, balancing responsibilities and renewable-specific management requirements. GNERA developed an in-house measurement concentrator that collects production data from every plant in its representation portfolio, forming the basis of its control centre and telemetry service. It expanded its service range beyond pure representation into adjustment and balancing markets, including secondary and tertiary regulation and Replacement Reserve, as well as price hedging, swaps, PPA valuation and the management and transfer of Guarantees of Origin. It also provides energy advisory services and sends clients regulatory notifications about possible updates in regulation or the sector. The company operates from Madrid, where its registered contact address is on Serrano Galvache, and from Getxo in Bizkaia, and it also lists an office in Rome, Italy, with a separate Italian contact address and email. Its portfolio of represented installations is described as strategically distributed in geographic and technological terms, which the company says allows it to reach optimal levels of hedging against deviation costs. The company presents itself under the banner "Our future is green" and continues to describe its mission as collecting, organising and interpreting the world's energy information and making it available to users to improve generation and consumption operations.
