Interest Free Yes Yes
Project Compliancy Criteria
Technical payback of less than 5 yearsLifetime cost of CO2 less than £100/tonneProject must be additional
Technical payback of less than 5 yearsLifetime cost of CO2 less than £100/tonneProject must be additional
Funding for Projects 100% Funded Matched Funded 50% PSO / 50% SALIX
Repayment The repayments will commence March 2011 and will be in 8 x 6 monthly equal instalments
No repayment as long as the recycling condition of minimum 60% reinvestment annually into projects is achieved
Salix Recycling Fund
• Provide a long term interest free recycling fund for investment in energy saving projects
• Salix funding is matched by client as a % of their energy bill
• Ring fenced fund is created within the organisation
• Initial funding is spent over two years
• Each individual project repays its cost back to the fund from the savings
Project Example – Car Park Lighting by Borough Council of King’s Lynn & West Norfolk (BCKLWN)
BEFORE:• 274x70W + 10x58W +48 x18W = 20.6kW• Operate for 18 Hours a day = 372kWh/day• 135,500kWh/year• £13,550/yr running costs
AFTER:• Installation of ‘Save it Easy’ e-Ballast conversion units, and replacement of T8 bulbs with T5 bulbs. • Load reduced by 32% down to 14.0kW• £3,112 energy saving / year projected• Technical payback 2.61 years• 22.5 tCO2 saved / year (projected)• 42,000kWh saved annually (projected)
