Efficiency in energy consumption

The Enel Group consumes energy to power its generation plant, through which it produces in its turn new energy which is distributed on the market. In 2016 there was a 15% fall in fuel energy consumption (the consumption of fossil fuels went from around 35.8 m. toe in 2015 to 32.8 m. toe in 2016) owing to the lower thermal production compared to the previous year. Fossil fuel is used almost entirely as a source of energy for thermal production. For Enel using energy efficiently means, on the one hand, maximizing the yield from the mix of sources (thermal, nuclear and renewables) and, on the other, making the distribution grid more efficient to avoid significant quantities of energy being lost along power transmission lines. Enel’s strategy to reduce energy consumption, therefore, envisages investments to increase efficiency in all the Group’s activities, from production to distribution, and also aims at disseminating greater awareness on energy use (see also the chapter “Decarbonization of the energy mix”). In 2016 work continued to increase the efficiency of power generation capacity. The implementation of the operational excellence programs continued thus optimizing the distribution of the production load.

Fuel consumption by primary source

The table below sets out the main initiatives adopted both for power plants and the local area with an indication of the country and the type of intervention.

COUNTRYTYPE OF INTERVENTIONDESCRIPTION OF INTERVENTION
EUROPE
RUSSIAThermal productionReftinskaya: saving of 6,594.2 GJ from unit 1 (3 actions planned for 2016 were rescheduled for 2017, including the retrofitting of unit 1 with heating plates, the reconstruction of the regenerative air heater, the change of the vacuum systems). The retrofitting of unit 8, with the replacement of the heating plates, ended in the final quarter of 2016. The impact on efficiency will be assessed in 2017. Nevinnomysskaya: saving of 13,398.72 GJ from organizational actions to increase energy efficiency and energy saving completed in 2016 which were less effective than the actions taken in 2015, when instruments were replaced. Konakovskaya: saving of 36,624.8 GJ from the retrofitting of units 1 and 2 in 2016.
SPAIN Thermal production3,163 GJ saved thanks to the redefinition of the minimum technical requirements at Alcúdia (the saving was calculated as the difference between the average outputs in 2015 vs. 2016, considering the hours for 2016 and specific consumption) and 0.61 GJ at Teruel thanks to the replacement of 2 mills of the Grupo-III with a more efficient model with the aim of reducing electricity consumption.
Electricity grid distributionLas Salinas: replacement of old light bulbs with a LED system.
ROMANIA Electricity grid distributionEnergy savings recorded at: Muntenia, 3,034.8 GJ; Dobrogea, 2,774.88 GJ; Banat, 3,170.88 GJ. These were due to the optimization of operations and the reconfiguration of the network, the balancing of the phase loading, with the final effect of reducing the network losses. This was possible due to the work done in the previous year.
MarketEnel Romania offered 400 energy-saving light bulbs (7.5 W) and 250 extension cables with switches, as part of a larger initiative which aims to improve access to energy and efficient consumption.
ITALYMarketOffer of energy efficiency products and services as Smart Energy Solution (SES) which enables companies to save up to 30% of energy consumption, reducing the impact of the cost of energy and keeping performance unchanged. Besides lighting, the technologies currently in the SES portfolio are: UPS, sub-metering, automation kits, ISO/DE service, factor correction units, microcogeneration, monitoring platform.
LATIN AMERICA
BRAZILInnovationThe demand management programs and the energy efficiency program offer savings of 46,270 MWh/year, and the reduction of demand at peak hours of 11,167 kW of energy. The initiatives include environmental education and replacing old equipment with more efficient models, and aim at more rational use of energy. In 2016, 59% of low-income participants in residential projects reduced their energy consumption. In addition, 211,917 computers were replaced with more efficient models certified with the seal of the Class A National Program for energy saving (PROCEL).
COLOMBIAInnovationA program was adopted of loans to buy electric bicycles which enabled a saving in emissions of 18.5 tons of CO2.
CHILEElectricity grid distributionTechnological renewal with the installation of 53,906 smart meters and 435 concentrators in 10 Municipalities of the area where the company has a concession.
PERUElectricity grid distributionFirst public lighting system installed with LED lights; with the installation of this technology a new project was also started for the development of the remote management system which enables optimization of energy use through the power and optimal regulation of the flow of light.
