Abstract
Description
This research work is focused on energy efficiency and sustainable development, which took
into consideration one of the essential fields and currently developing energy storage, making
a brief comparison between the different technologies and focusing on to conventional and flow
batteries as a case study. A bibliographic compilation of data on the batteries was carried out to
determine the advantages and disadvantages that they have in the economic, environmental,
maintenance costs, implementation costs and the technical characteristics they have such as
charge/discharge cycles, energy density, performance among other parameters. The researcher
proceeded to use the historical data of the daily demand of an industry, later by analyzing this
parameter, the rules of the tariff schedule of ARCONEL 007/00 were applied to evaluate its
monthly consumption incidence and the benefits that have to correct the pattern of daily demand
in its peaks and valleys to reduce the payment of the electric sheet using programs such as
EXCEL for the simulation of load profiles, NEPLAN for flow diagrams and schemes. The
mathematical financial formulas (NPV, IRR, NPV-INVERSION, and PAYBACK) were
applied for the evaluation of the project, observing the economic viability for the
implementation. The plan shows the economic benefits of leveling the load pattern according
to the different time bands when applying the rate schedule. The application of the batteries in
the Ecuadorian electrical system as an alternative for energy storage and leveling of the curve
due to the low cost of electric power is not viable yet since in a predominance system of a
hydraulic generation that is considered the cheapest compared to the other generation systems.
Despite this observation, it is an excellent alternative for incorporation in non-conventional
generation systems (solar, wind), due to its oscillation and storage difficulty. This research
aimed to solve the necessity to select the appropriate technology when implementing the flow
batteries (REDOX) in an industry, observing its technical and economic benefits, and the
analysis to proceed to determine an implementation project of this technology and the curves
resulting from the daily demand of the industry.
