Moneleg, S.L. is a Spanish company specialised in electrical engineering, energy efficiency, and renewable energy. Established in 1984, its origins date back to the late 1970s. Over its more than 40 years of track record, it has consolidated its position in the sector through a progressive evolution from electrical network maintenance to the integration of advanced energy efficiency solutions.

The company is headquartered in the province of Cádiz and carries out projects across the entire national territory. Its activities include the execution of medium- and low-voltage electrical infrastructure, industrial maintenance, photovoltaic installations (self-consumption and solar plants), energy communities, efficient lighting, energy service contracts (ESCO), and energy audits for SMEs, large facilities, and public administrations.

In recent years, Moneleg has expanded its business lines towards the technical management of energy efficiency measures aimed at obtaining Energy Savings Certificates (CAE), operating as an accredited Delegated Party before the Ministry for Ecological Transition. In this capacity, it manages the acquisition, verification, registration, and sale of CAEs generated both from its own interventions and through agreements with companies in the energy sector and other non-accredited entities.

Since 2016, Moneleg has been part of a corporate group that also includes Elega Energía, S.L., an independent electricity retailer focused on indexed tariffs and self-consumption solutions with nationwide coverage. The relationship between the two entities is not only shareholding-based: Elega Energía acts as an Obligated Party and purchaser of part of the CAEs handled by Moneleg, and has also issued a comfort letter in support of this financing transaction, undertaking to back Moneleg in fulfilling its obligations towards investors.

Both companies, together with a third entity —Lomas del Taraje, S.L.—, form a corporate group whose majority ownership is held by the same individual, ensuring alignment of interests in project execution, the group’s financial stability, and the fulfilment of the commitments undertaken.

Overall, Moneleg combines the technical capabilities of an established engineering company with the specialised expertise required to operate within the new regulatory framework of the CAE system, supported by a vertically integrated business network that strengthens its solvency and execution capacity.

Moneleg operates across three complementary and vertically integrated business lines:

1. Electrical engineering and infrastructure. This is the company’s core historical activity, covering the design, execution, and maintenance of complex electrical installations: distribution networks, substations, urban infrastructure, industrial, naval, and hospitality facilities. This business line generates long-term contracts with both public and private clients and forms the foundation of Moneleg’s technical reputation.

2. Energy efficiency and improvement measures. Building on its expertise in electrical installations, Moneleg delivers energy efficiency projects for companies, communities, and institutions: replacement of lighting with LED technology, improvements to building envelopes and insulation, upgrading of HVAC systems, and optimisation of energy management systems.

3. CAE management as a Delegated Party. This is the most recent and fastest-growing business line. As an authorised and accredited Delegated Party, Moneleg acquires the rights to energy savings generated both by its own activities and by third-party partners (installers, electric vehicle dealerships, homeowners’ associations, hotels, hospitals), manages verification and administrative processing, and transfers the resulting CAEs to Obligated Parties —large energy retailers and operators— with which it maintains assignment agreements. This activity has grown from 0 to 8.5 GWh managed in 2025, with a target of 14 GWh in 2026.

The vertical integration of the corporate group —with Elega Energía, as an electricity retailer, also acting as an Obligated Party and direct purchaser of CAEs— generates operational synergies and ensures a partially guaranteed outlet for the certificates managed by Moneleg.

Why these SDGs?

• SDG
  7
  SDG 7: Ensure access to affordable, reliable, sustainable and modern energy for all. The CAE system is an energy policy instrument directly aligned with target 7.3 of the 2030 Agenda (doubling the global rate of improvement in energy efficiency). Moneleg acts as a catalyst for efficiency within the productive and residential fabric of the province of Cádiz, enabling consumers and companies that have invested in energy-saving measures to recover part of the value generated through certificates.
• SDG
  8
  SDG 8: Promote sustained, inclusive and sustainable economic growth, full and productive employment and decent work for all. With a workforce of approximately 140 employees, Moneleg is a significant employer in Chiclana de la Frontera and the province of Cádiz. The growth of its CAE management activities generates stable, skilled technical employment at the local level. In addition, the CAE system stimulates the activity of installers, technicians and energy service companies across the wider economic ecosystem with which Moneleg collaborates.
• SDG
  9
  SDG 9: Build resilient infrastructure, promote inclusive and sustainable industrialisation and foster innovation. Moneleg’s long-standing activity in electrical infrastructure —distribution lines, substations, transport infrastructure such as the Cádiz Bay Tram— directly contributes to the modernisation and resilience of the region’s energy infrastructure. The integration of CAE management as a new business line reflects the company’s ability to innovate and adapt to new paradigms in the energy sector.
• SDG
  11
  SDG 11: Make cities and human settlements inclusive, safe, resilient and sustainable. Energy efficiency measures certified through the CAEs managed by Moneleg include improvements in residential buildings, homeowners’ associations, municipal facilities and public spaces. These actions reduce energy consumption in the building stock, improve thermal comfort for citizens and contribute to reducing energy poverty in urban and peri-urban areas.
• SDG
  13
  SDG 13: Take urgent action to combat climate change and its impacts. The reduction of CO₂ emissions is the most direct environmental outcome of the CAE system. The 575 tonnes of CO₂ avoided annually through the certificates managed in this transaction contribute, within the framework of national and European climate action plans, to Spain’s decarbonisation pathway under the National Integrated Energy and Climate Plan (PNIEC 2021–2030) and the European Green Deal.
• SDG
  17
  SDG 17: Strengthen the means of implementation and revitalise the global partnership for sustainable development. Crowdfunding through Ener2Crowd is, in itself, a partnership instrument between private investor capital —with participation starting from €300— and companies implementing the energy transition on the ground. This partnership democratises access to investment in the energy sector and mobilises private capital towards sustainability objectives that would otherwise remain limited to institutional investors. The model is replicable and scalable, in line with the spirit of SDG 17.

Beyond the direct impact of this specific package, the CAE mechanism has a multiplier effect on investment in energy efficiency within the Spanish economy that is worth highlighting. Participatory financing channelled through Moneleg, acting as a Delegated Party, functions as a key component within this mechanism: it enables the scaling up of certified activities that would otherwise not be implemented due to a lack of liquidity to pre-finance processing costs.

According to data from the Ministry for the Ecological Transition and the Demographic Challenge (MITECO), since its implementation the CAE system has catalysed more than 1,200 energy efficiency measures, generating cumulative savings of 2 TWh per year and avoiding approximately 500,000 tonnes of CO₂ emissions, equivalent to around 1% of the annual emissions of the national industrial sector. The system’s growth potential is significant: Order TED/133/2026 increases the obligations of Obligated Parties, implying rising demand for certificates in the coming years.

Moneleg’s local commitment to the environment goes beyond its role as a Delegated Party. The company has integrated sustainability into its corporate identity, as illustrated by the planting of more than 100 pine trees in Novo Sancti Petri (Chiclana) as a symbolic initiative marking its 40th anniversary, publicly recognised by the National Association of Energy Services Companies (ANESE). Although modest in absolute environmental impact terms, this initiative reflects the cultural commitment of a company that works daily to make energy efficiency a measurable reality within the productive fabric of southern Spain.

The present transaction will finance the acquisition, verification and transfer of a package of 2.3 GWh (2,300 MWh) of Energy Saving Certificates (CAEs). Each CAE represents one kilowatt-hour of final annual energy savings certified by an accredited entity. This volume of certificates reflects the implementation of energy efficiency measures that generate direct savings equivalent to the annual electricity consumption of approximately 742 average households in Spain.

It is important to note that the environmental benefit is not attributable to the certificate as a document, but to the underlying energy efficiency measures that make it possible: replacement of lighting systems with LED technology, improvements in thermal insulation, upgrading of industrial equipment, installation of high-efficiency HVAC systems, and electrification of transport, among others. The CAE is the financial mechanism that makes these measures economically viable and scalable.

Proportionally, energy savings of 2,300 MWh/year result in the avoidance of approximately 575 tonnes of CO₂ per year, based on the emission factor of the Spanish electricity system of 0.25 tCO₂/MWh (reference value from the Ministry for the Ecological Transition and the Demographic Challenge, MITECO).

Environmental equivalences
To make the impact of the 575 tonnes of CO₂ avoided annually more tangible, the following equivalences help contextualise this figure:

575

tonnes of CO₂/year avoided

Emissions prevented from being released into the atmosphere thanks to the energy efficiency measures underlying the managed CAEs.

47,725

equivalent trees

Equivalent to ~189 football fields covered with forest mass, calculated at 83 trees per tonne of CO₂ absorbed.

~278

cars removed from circulation/year

Equivalent to eliminating the annual emissions of 278 internal combustion vehicles (average emissions: ~130 g CO₂/km, 16,000 km/year).

742

equivalent households

Energy savings of 2,300 MWh/year are equivalent to the annual electricity consumption of approximately 742 average Spanish households (average consumption: ~3,100 kWh/household/year).

Estimates calculated by Ener2Crowd. Emission factor: 0.25 tCO₂/MWh (MITECO). Tree equivalence: 83 trees/tCO₂ (IDAE). Average household consumption: 3,100 kWh/year (INE/IDAE). Vehicle emissions: ~2.08 tCO₂/year.
