Achieving net zero requires a robust renewable energy procurement strategy potentially spanning both onsite generation and contracting grid-scale projects. Renewable Energy Guarantees of Origin (REGO) are not enough, nor will they help the UK to decarbonise fully by 2050. Energy supply security at competitive, stable prices is fundamental to all organisations, yet achieving this is challenging given the range of technology and regulatory challenges that exist. Optimised has a team of experts to advise on corporate Power and Gas Purchasing Agreements (PPAs and GPAs) as well as onsite generation, spanning wind, solar, biomass and Battery Energy Storage Systems (BESS).

BESS stands for Battery Energy Storage Systems and is often installed alongside renewable energy generation such as wind, solar and biomass. BESS aims to reduce the export whilst increasing the site’s consumption of the energy it has generated. This helps to build resilience and energy self-reliance of the site. 

A corporate Power Purchase Agreement (or CPPA) is an upfront supply contract between a buyer and a seller of renewable energy. The seller is usually a renewable electricity generator, and the buyer would be a licensed supplier. These agreements usually last 5-20 years, and the deals Optimised work with normally last 10-15 years.

A Gas Purchase Agreement (GPA) is a long-term contract between a biogas or biomethane producer and a consumer, for the produced output during an agreed time.  It is the gas equivalent of a PPA, which concerns only electric power. 

These agreements help finance renewable energy projects or re-power existing assets. You thereby reduce energy dependence on non-renewable sources, lower greenhouse gas emissions, and stabilise long-term costs.
