Distributed Energy Resources (DER) Programme

In alignment with the Integrated Resource Plan (IRP) undertaken in 2017, and the National Energy Policy, a new programme for the growth of customer-owned, distributed renewable generation was introduced in January 2018 after review and approval by the Utility Regulation and Competition Office (OfReg). The programme has an initial allocation of 3 MW of capacity for customer participation. In 2019, with OfReg approval for CUC’s 20 MW battery storage project, an additional 12 MW of capacity is expected to be made available for the DER programme upon completion of the battery installation, which will allow for more distributed renewable generation to be interconnected without detrimental effect on grid operations.

The Distributed Energy Resources (DER) Programme allows for customers to self-consume electricity generated by their own renewable energy system, avoiding equivalent consumption-related charges from the grid in doing so via net-metering. Additionally, customers are able to sell to CUC any excess electricity produced and exported to the grid at an avoided cost-of-generation credit rate. Incorporating the lessons learned by other jurisdictions from early net-metering programmes, DER customers are billed with a demand rate structure. The use of demand rates aligns the fixed costs of providing a grid interconnection and standby provision to the customer with demand charges, avoiding any potential cross-subsidization of service assets.

The DER Programme will allow for the continued growth and participation of customers in the renewable energy sector, which will help to reduce greenhouse gas emissions and the country’s carbon footprint.

Interim Renewable Infusion Study

The study was completed and circulated in March 2017:

CORE Programme

The Company remains fully dependent on diesel fuel for generation despite continued efforts to employ renewable sources.

With the introduction of Consumer Owned Renewable Energy ("CORE") tariffs in early 2009, the Company entered a new era of relationship with a component of its customer base. Customers with an interest in environmentally friendly renewable generation may now connect to CUC's distribution grid and receive credits for generated power.

In 2011, the CORE Programme was revised and approved by the Electricity Regulatory Authority ("ERA") culminating in the Feed-In-Tariffs ("FIT") Programme. FIT provides for CUC to purchase energy from CORE generators at a rate approximate to the true cost of the renewable energy and to pass this cost through in the fuel factor.

In August 2012, the ERA approved revisions to the existing FIT Programme, which has been in place since February 2011.

In April 2015, May 2016, May 2017, February 2018 and March 2019, the ERA approved further revisions to the existing FIT Programme.

The FIT Programme reflects current successful practice in Europe and North America for the promotion of consumer generated renewable energy.

Integrated Resource Plan (IRP)

The final report on the Integrated Resource Plan (IRP) is attached:

5MW Solar Farm

 

 

The 5MW Solar Farm is the first commercial solar project in the Cayman Islands. It was completed and commissioned in June 2017 and is located on a 20-acre site in Bodden Town, Grand Cayman. The Farm comprises 21,690 poly-crystalline photovoltaic (solar) modules each with a DC-rated capacity of 305 watts.

The facility is connected to CUC’s Bodden Town Substation and provides energy to power approximately 800 homes with clean renewable solar energy.
