1 Smart energy grid using local energy resources

2 Urban transformation Marina del Prat Red is now a part of the city of marked industrial profile, a place with industrial buildings, warehouses, solar uses and a small group of houses. On 1st June 2006, was approved the modification of the PGM of La Marina. Its objective is transforming existing applications into a new neighborhood that combine houses and economic activity, fully integrated in the city next to Zona Franca and with a population size and activity, similar to the rest of the city. 2

3 Model Zero emissions district Mobility Air quality Green areas Compatibility between residential and economical activity Residential : apartments (74% space) Economical activity: sq meters 3

4 Contract Creation of a new company participated by the Municipality to manage the project. (Collaboration Public-Private) 30 years + 10 Risk for demand. At he end of the contract, Municipality will be the owner of all the installations: buildings, machines, pipes m m2 Pabellón m m m2 Hotel Comercio Vivienda protegida Vivienda libre Oficinas m2 Congresos 0 m

5 Available local renewable energy resources In the path to reduce C02 emissions, Barcelona Municipality has done a prospect of potential local energy sources: Solar : in 2000 Barcelona approved a local law that regulates the use of thermal solar energy in new buildings. Biomass: Originated in the city. Cold as waste from an industrial process. 5

6 Thermal solar Present regulation just cover the use for heat water generation. Maximum generation peak (summer) match with minimum demand, that means that the energy produced during this period is lost. 6

7 Biomass Generation of ton of biomass each year. Opportunity to make an energy use for this biomass. 7

8 Residual cold from an industrial process At Barcelona s port a gasification plant provides natural gas for the city. Natural gas arrives as LNG (Liquid Natural Gas) and is storage. The conversion of LNG (-160ºC) to natural gas is done using sea water (15ºC) as a warm fluid. Sea water is cooled in that process, and returned to the sea. 30 MWh are lost. 8

9 Grid operation. Atlantis Power Plant: Heating and cooling production: energy mix (gas, biomass, solar, electricity) Energy conversion: heating installation, combined heat power Biomass Energy Performance operation centre Industrial sites: energy and environmental efficiency (steam, electricity, industrial gas, DHW, Cooling, Heating) Residential buildings: thermal plant management, domestic hot water (DHW) Sports Facilities Office buildings, conference centres: DHW, Cooling, Heating Healthcare: DHW, Cooling, Heating 3 - Substation The substation is the point of entrance of the primary network fluid into the building. Here is situated the energy meter. At the heat exchanger, the hot water provided heats separately the domestic water (that is used at the taps and showers) and the radiators water. The chilled water provided cools the air using air-conditioning units or fan-coils. Schools DHW, Cooling, Heating Delivery Hot water is then distributed to the users at the different floors into a closed pipe circuit (the secondary network). In the same way, chilled water also is distributed to the users. District Heating & Cooling networks: energy and environmental efficiency 1 - Power plant Production of 90ºC hot water, 5ºC chilled water and -10ºC industrial cooling Thermal production installations (biomass, gas boilers ) Chilling water installations Pumping and control equipment 2 - Distribution network Insulated piping system (primary network) of cold and hot water that transmits energy from the power plant to the point of usage (substation)

10 Energy grid as a smart solution Distributed generation: profit of the renewable energy sources as close as possible of it s origin. Generation on demand: On-line connection between clients and DHC with optical fiber allows to use at each moment the best mix of energy sources. Data is collected to make profiles and forecasts. Capacity for storage exceeding energy: Periods with low demand allows to charge cold storages. Demand aggregation: different buildings uses (residential, offices, commercial, industrial) means different profiles that can be overlapped to plain demand curve. Advantages: Better performance that individual solutions. Reduction of CO2 emissions. 10
